WEBVTT 1 00:00:13.560 --> 00:00:14.300 Learning meeting 2 00:00:14.300 --> 00:00:16.860 If you care about the home page of the library 3 00:00:17.080 --> 00:00:17.980 Database words 4 00:00:17.980 --> 00:00:20.160 These are all by press. 5 00:00:20.160 --> 00:00:23.410 Let's say sci has a platform 6 00:00:23.410 --> 00:00:26.890 Some of our important academic resources 7 00:00:26.890 --> 00:00:33.620 Especially some databases like 3cx 8 00:00:34.640 --> 00:00:35.960 The academic level is very high. 9 00:00:35.960 --> 00:00:37.550 Of course, the price is also very expensive. 10 00:00:37.700 --> 00:00:39.880 So this is according to the press. 11 00:00:40.010 --> 00:00:42.170 There is also in accordance with the resource integrator to come. 12 00:00:42.170 --> 00:00:46.830 For example, some database learning like stops will. 13 00:00:46.830 --> 00:00:49.040 Like HV, right? 14 00:00:49.040 --> 00:00:53.450 And then the sa1 car 15 00:00:53.450 --> 00:00:56.090 Or the society of civil engineers 16 00:00:56.090 --> 00:01:04.930 ASCE of the American society of civil engineers seems to be and so on. 17 00:01:04.930 --> 00:01:07.550 They also have their own platform. 18 00:01:08.800 --> 00:01:14.510 Well, first of all, we may be more useful is the discovery of resources of such two systems. 19 00:01:15.370 --> 00:01:17.680 We have three doors to worry about. 20 00:01:18.050 --> 00:01:21.100 We found that both systems can be tried. 21 00:01:21.320 --> 00:01:24.500 I can't tell you much about time. 22 00:01:25.120 --> 00:01:29.370 And then we look at it and say, for academic research 23 00:01:29.370 --> 00:01:33.330 We think that the most important thing is foreign language periodicals. 24 00:01:34.750 --> 00:01:36.500 Undergraduates may not be able to use it. 25 00:01:36.500 --> 00:01:39.400 Or not all undergraduates will use it. 26 00:01:39.660 --> 00:01:41.690 But in the future, if you want to do research. 27 00:01:41.690 --> 00:01:44.560 If you want to further study. 28 00:01:45.530 --> 00:01:46.820 Master's degree 29 00:01:46.820 --> 00:01:48.260 Even a doctor's degree 30 00:01:48.450 --> 00:01:51.060 We say read a doctor, read a doctor. 31 00:01:51.060 --> 00:01:53.170 If you don't look at the foreign literature 32 00:01:53.170 --> 00:01:54.740 Don't take this degree. 33 00:01:54.740 --> 00:01:56.020 There's no way to get it 34 00:01:56.020 --> 00:02:00.730 Then the most important foreign language literature is foreign language periodicals. 35 00:02:01.630 --> 00:02:05.190 We have a lot of this kind of some databases. 36 00:02:05.310 --> 00:02:05.790 Here 37 00:02:07.290 --> 00:02:08.090 Listed 38 00:02:08.330 --> 00:02:11.590 C giant rk and a little tired sb 39 00:02:11.650 --> 00:02:20.010 Sb is all the academic teachers and students I just mentioned. 40 00:02:20.010 --> 00:02:22.990 I don't think I can get around some of these databases. 41 00:02:23.620 --> 00:02:27.420 Then, of course, there are some e-books. 42 00:02:28.060 --> 00:02:29.600 If there are more undergraduates 43 00:02:29.600 --> 00:02:34.740 In particular, I would recommend you to use the worry and the student's e-book. 44 00:02:35.520 --> 00:02:44.110 I used to buy books on my own. 45 00:02:44.900 --> 00:02:45.950 Homework to buy books 46 00:02:45.950 --> 00:02:48.490 But later it was discovered that buying a book was still quite expensive. 47 00:02:48.490 --> 00:02:49.160 I won't buy it. 48 00:02:49.160 --> 00:02:50.730 Start with 49 00:02:51.150 --> 00:02:54.000 Because we have these two databases 50 00:02:54.100 --> 00:02:57.060 Start reading electronic books with some library resources 51 00:02:57.920 --> 00:03:02.730 If an undergraduate needs a book 52 00:03:02.730 --> 00:03:03.830 The words of Chinese books 53 00:03:03.830 --> 00:03:05.990 These two databases are still very useful. 54 00:03:06.380 --> 00:03:08.310 Of course, they still have shortcomings. 55 00:03:08.910 --> 00:03:10.980 I don't talk much about time. 56 00:03:10.980 --> 00:03:17.010 So these are electronic books 57 00:03:17.190 --> 00:03:19.090 You can go and see 58 00:03:20.080 --> 00:03:22.230 So besides books and magazines 59 00:03:22.230 --> 00:03:23.920 In fact, it is better to do research. 60 00:03:23.920 --> 00:03:25.840 Or check the data 61 00:03:25.840 --> 00:03:28.890 Some of the resources that we tend to overlook 62 00:03:29.140 --> 00:03:32.110 There is a research report at the beginning. 63 00:03:32.260 --> 00:03:34.410 Survey reports and yearbooks 64 00:03:34.410 --> 00:03:36.680 In fact, the yearbook is very useful. 65 00:03:36.680 --> 00:03:41.700 For example, our research in the field of urbanization. 66 00:03:41.940 --> 00:03:44.550 We're going to need some data 67 00:03:45.100 --> 00:03:48.100 For example, what data for the past ten years? 68 00:03:48.100 --> 00:03:50.140 What are the data of Shanghai in the past ten years? 69 00:03:50.140 --> 00:03:51.870 What data are there in Beijing? 70 00:03:52.430 --> 00:03:55.890 These can often be found in the yearbook. 71 00:03:56.250 --> 00:04:03.020 So if we say to do research or even understand 72 00:04:03.330 --> 00:04:04.170 Write a small paper 73 00:04:04.370 --> 00:04:09.650 You may be, I don't know if the undergraduate course is going to write a small paper. 74 00:04:09.740 --> 00:04:11.690 Because graduate students are writing 75 00:04:11.950 --> 00:04:13.330 So when you write a little paper 76 00:04:13.330 --> 00:04:15.350 You need to do some research. 77 00:04:15.350 --> 00:04:20.610 Because of the cost, you can't do your own research. 78 00:04:20.780 --> 00:04:23.930 So these yearbook statistical reports 79 00:04:24.620 --> 00:04:27.550 This is a very important resource. 80 00:04:35.150 --> 00:04:41.210 All these should be said to be libraries. 81 00:04:41.690 --> 00:04:47.610 What you have can go deep into the excavation of some of these academic resources. 82 00:04:47.860 --> 00:04:52.420 Then take a break 83 00:04:52.680 --> 00:04:54.110 After the break 84 00:04:54.300 --> 00:04:57.770 I'm going to talk to you about abstract databases 85 00:04:57.920 --> 00:04:59.640 If you haven't heard of it before 86 00:04:59.820 --> 00:05:02.070 I'm sure there's nothing to say about this. 87 00:05:02.560 --> 00:05:04.640 I think we'll have a rest. 88 00:05:04.870 --> 00:05:05.900 Go on 89 00:05:09.410 --> 00:05:11.180 Start the next lesson 90 00:05:12.050 --> 00:05:16.410 I just said why the abstract database is so important. 91 00:05:16.790 --> 00:05:18.290 You just saw 92 00:05:18.820 --> 00:05:22.810 If I say doing research in foreign language journals is particularly important. 93 00:05:23.030 --> 00:05:28.080 But there are a lot of these databases, if you want to look up. 94 00:05:28.080 --> 00:05:32.770 That is, every database, you have to enter a database interface. 95 00:05:33.120 --> 00:05:35.650 Into a database platform 96 00:05:36.520 --> 00:05:38.220 Check the C system 97 00:05:38.220 --> 00:05:40.360 You might just show off the taste buds 98 00:05:40.780 --> 00:05:43.450 Unless you go all over again 99 00:05:43.780 --> 00:05:44.680 Still leak 100 00:05:44.740 --> 00:05:48.000 We will also miss some of the databases we did not buy. 101 00:05:48.000 --> 00:05:51.420 So we do research in general 102 00:05:51.420 --> 00:05:53.960 We all start with abstract databases 103 00:05:55.050 --> 00:05:57.340 This is a very good one 104 00:05:57.340 --> 00:06:02.300 Or rather, it is a habit that should be promoted. 105 00:06:02.300 --> 00:06:04.560 Is that everyone from the database. 106 00:06:04.560 --> 00:06:06.660 Because he earns too much 107 00:06:07.570 --> 00:06:09.970 Articles in the journal 108 00:06:10.210 --> 00:06:13.370 So let's say the piece of webofnote 109 00:06:14.480 --> 00:06:19.380 It receives more than 5000 kinds of periodicals. 110 00:06:20.020 --> 00:06:25.780 But this is very, very different areas, very core of these journals. 111 00:06:27.560 --> 00:06:33.020 And then there is the bosstop home, which for me is more extensive. 112 00:06:33.640 --> 00:06:37.280 The core of the journal he searched was not 113 00:06:37.480 --> 00:06:41.870 No core from the webofknowledge database 114 00:06:42.390 --> 00:06:47.730 But the results are interesting. 115 00:06:48.810 --> 00:06:51.670 I'd like to say a few extra words. 116 00:06:51.670 --> 00:06:54.290 We have made a comparison between the two databases. 117 00:06:56.700 --> 00:07:04.090 Microblog attached to the social media by the Chinese government and 118 00:07:04.090 --> 00:07:07.650 The university is used for academic evaluation. 119 00:07:07.650 --> 00:07:12.590 The evaluation of scientific research performance 120 00:07:12.750 --> 00:07:16.520 Many of our schools have not been very ideal. 121 00:07:17.080 --> 00:07:17.600 What to do 122 00:07:17.740 --> 00:07:20.040 Let's do scope analysis 123 00:07:20.420 --> 00:07:21.420 Found boss 124 00:07:21.420 --> 00:07:22.270 Sit down 125 00:07:22.560 --> 00:07:27.370 For example, we Tongji through the micro-blog classification of production words. 126 00:07:28.320 --> 00:07:32.500 Our ranking is like this. 127 00:07:32.590 --> 00:07:34.510 How many places, for example 128 00:07:34.510 --> 00:07:36.140 Then do it with step 1 129 00:07:36.320 --> 00:07:37.680 Our ranking is very good. 130 00:07:38.710 --> 00:07:40.580 Let's analyze what's going on. 131 00:07:40.680 --> 00:07:45.120 Later, it was found that the two databases earned different journals. 132 00:07:45.250 --> 00:07:49.200 And supers it has a lot of noncore journals 133 00:07:50.190 --> 00:07:54.000 In other words, in the core journal of the publication of papers on the order above. 134 00:07:54.260 --> 00:07:56.890 Probably not very ideal 135 00:07:56.890 --> 00:08:02.190 This has a direct impact on the ranking is the university's ranking. 136 00:08:02.420 --> 00:08:04.920 So in the supers database 137 00:08:04.920 --> 00:08:09.550 We can also show that our number of published papers is good. 138 00:08:09.550 --> 00:08:14.930 But our core level is not very high. 139 00:08:14.930 --> 00:08:16.890 So the two databases are such a relationship. 140 00:08:16.890 --> 00:08:19.680 As soon as I say, we may say so. 141 00:08:19.680 --> 00:08:24.120 Perhaps we will be able to compare the image to understand their differences. 142 00:08:24.450 --> 00:08:31.850 Of course, if one of your topics is looking for revenge, the journal is not very ideal. 143 00:08:31.850 --> 00:08:35.420 I suggest you check it in sicos 144 00:08:35.620 --> 00:08:39.120 Although it has some non-core journals. 145 00:08:39.120 --> 00:08:43.020 But maybe it can be your reference. 146 00:08:46.880 --> 00:08:50.020 Our library bought thirty square thirty 147 00:08:50.020 --> 00:08:56.340 Fang Ding loves to buy databases. 148 00:08:56.750 --> 00:08:58.540 That's what I just said. 149 00:08:58.540 --> 00:09:04.060 As point data publishers are very cattle of a publisher. 150 00:09:04.060 --> 00:09:08.210 All the academic information he gave was very good. 151 00:09:08.440 --> 00:09:10.780 So as long as it is not all good data. 152 00:09:10.780 --> 00:09:12.600 But we especially hate him. 153 00:09:12.600 --> 00:09:14.510 Because his things are very expensive. 154 00:09:20.360 --> 00:09:25.530 I just said that there are 29 funds in the field of urbanization, which are open applications. 155 00:09:25.700 --> 00:09:28.900 It is through the three corners that we check. 156 00:09:28.900 --> 00:09:34.540 This is a database of fund projects in the field of science. 157 00:09:34.720 --> 00:09:38.720 Is also sb's data publishing company. 158 00:09:39.020 --> 00:09:41.970 Then all of his databases were very expensive. 159 00:09:41.970 --> 00:09:46.260 So we've been doing publicity on every occasion. 160 00:09:46.260 --> 00:09:48.840 Said you were going to use the sci database 161 00:09:48.840 --> 00:09:50.440 You're going to use 3 svector 162 00:09:50.440 --> 00:09:52.960 Because we wanted us to pay so much 163 00:09:52.960 --> 00:09:56.700 We want all our teachers and students to use the database. 164 00:09:56.700 --> 00:09:58.510 Otherwise, it would be too bad. 165 00:10:01.320 --> 00:10:05.870 This is about some of our resources ahead. 166 00:10:05.870 --> 00:10:07.310 If you want to do academic research 167 00:10:07.450 --> 00:10:10.310 Basically, these resources may need to be used in the front. 168 00:10:10.750 --> 00:10:13.130 And then we're going to talk about analytical tools 169 00:10:13.230 --> 00:10:14.470 Analyzers have two kinds 170 00:10:14.470 --> 00:10:20.040 One is that some database platform with analytical tools. 171 00:10:20.360 --> 00:10:27.180 I'm just talking about the web of knowledge platform. 172 00:10:28.080 --> 00:10:29.500 In fact, if an undergraduate 173 00:10:29.500 --> 00:10:38.770 I suggest that you use the CNKI first to see a lot of similar functions I will talk about sort. 174 00:10:38.770 --> 00:10:40.080 Distribution of this field 175 00:10:41.100 --> 00:10:43.300 Refining, deworming, etc. 176 00:10:43.420 --> 00:10:44.840 There can be many such tools. 177 00:10:44.840 --> 00:10:47.490 You will know it by touching it a little. 178 00:10:47.650 --> 00:10:50.170 So what I'm talking about here is micro-blog 179 00:10:50.440 --> 00:10:54.810 Well, worth is such a abbreviation that is quite used to it. 180 00:10:54.810 --> 00:10:56.150 Is webofscience 181 00:10:56.150 --> 00:11:00.520 But it's actually a webofnot 182 00:11:00.520 --> 00:11:03.290 Because it includes three 183 00:11:03.480 --> 00:11:07.890 These three retrieval epitome outside. 184 00:11:07.890 --> 00:11:10.590 There are other databases. 185 00:11:10.950 --> 00:11:15.920 So let's do a process like this 186 00:11:15.920 --> 00:11:17.070 A case process 187 00:11:17.070 --> 00:11:23.600 How architecture does scientific research with the help of the web science series 188 00:11:24.400 --> 00:11:30.480 I will try this theme of urbanization. 189 00:11:31.020 --> 00:11:37.660 Let's see how to use the three databases of the web science series 190 00:11:37.660 --> 00:11:41.620 To find highly influential papers in the field 191 00:11:41.620 --> 00:11:45.430 How to find the literature of this subject in this field? 192 00:11:45.430 --> 00:11:48.690 How to understand the general development trend of this subject? 193 00:11:48.690 --> 00:11:53.460 How to find relevant papers quickly in retrieval 194 00:12:00.730 --> 00:12:02.800 What is the microblog Sanda? 195 00:12:02.910 --> 00:12:12.300 In fact, it is an American one, in fact, a method invented by librarians. 196 00:12:12.300 --> 00:12:20.390 Well, it's actually a point to take a document as a point. 197 00:12:20.740 --> 00:12:25.920 Such a way to track the development of an idea 198 00:12:26.070 --> 00:12:27.730 This is one of his research results. 199 00:12:27.730 --> 00:12:31.960 But then it became three things 200 00:12:32.040 --> 00:12:33.190 Three products 201 00:12:33.780 --> 00:12:35.180 We can have a look. 202 00:12:35.520 --> 00:12:37.220 That's the picture 203 00:12:39.640 --> 00:12:43.200 For example, this document was published in 2001. 204 00:12:43.200 --> 00:12:49.200 Then, in 2003 and 2004, two papers cited it. 205 00:12:49.410 --> 00:12:54.650 Then he referred to the three documents himself. 206 00:12:55.060 --> 00:12:57.130 It cites three documents 207 00:12:57.310 --> 00:13:01.040 And then the three documents related to the peripheral. 208 00:13:01.320 --> 00:13:03.180 For example, related to the literature. 209 00:13:03.180 --> 00:13:06.860 There is a literature related to this document. 210 00:13:06.860 --> 00:13:10.790 This diagram is a more vivid description. 211 00:13:10.960 --> 00:13:15.630 Scassca and ahci are webofscience 212 00:13:15.740 --> 00:13:19.870 In their inner being 213 00:13:20.230 --> 00:13:27.110 Why can we do some data like the urbanization I just showed you? 214 00:13:27.110 --> 00:13:28.070 Chart 215 00:13:28.300 --> 00:13:30.920 All the principles come from this 216 00:13:31.210 --> 00:13:36.350 So if we look through the references 217 00:13:36.350 --> 00:13:40.770 That is, you can look into a topic more and more. 218 00:13:41.030 --> 00:13:46.030 As you may know, I have a document published in a journal. 219 00:13:46.030 --> 00:13:48.930 I refer to this document. 220 00:13:50.140 --> 00:13:53.140 ... the literature of such authors as zhangsanlisi. 221 00:13:53.140 --> 00:13:56.340 You can go to the literature of Zhang san Li Si through you. 222 00:13:56.340 --> 00:13:57.840 Then the more you look, the deeper it gets. 223 00:13:58.200 --> 00:13:59.000 It's a lead 224 00:13:59.000 --> 00:14:07.890 That is to say, my literature, others, you can look up from my literature to the author who introduced me. 225 00:14:07.890 --> 00:14:13.030 So that means you'll look up new tea more and more to the latest literature. 226 00:14:13.030 --> 00:14:14.800 The literature is more and more extensive. 227 00:14:22.030 --> 00:14:25.460 Sci is actually a scientific citation index 228 00:14:25.660 --> 00:14:30.220 I just may be him because there is one that is the extended version. 229 00:14:30.220 --> 00:14:31.380 So much more 230 00:14:31.580 --> 00:14:34.140 The original core version should be more than 5000 kinds. 231 00:14:34.140 --> 00:14:35.650 There are now more than 8000 kinds. 232 00:14:35.850 --> 00:14:39.360 So the social sciences can also be reduced to more than 2, 800 kinds. 233 00:14:39.360 --> 00:14:41.830 There are a number of subjects involved. 234 00:14:41.990 --> 00:14:49.780 Then the ahca of arts and humanities, which is the core of 1500, and so on. 235 00:14:51.410 --> 00:14:51.760 Well 236 00:14:51.760 --> 00:14:53.730 So how to find him 237 00:14:54.690 --> 00:14:56.390 We might go to the home page 238 00:14:56.390 --> 00:14:59.770 And then there's a hot one 239 00:15:02.350 --> 00:15:04.950 Is it called a major database or a hot database? 240 00:15:04.950 --> 00:15:06.350 There's a webof in this 241 00:15:06.350 --> 00:15:08.670 Science you might see 242 00:15:08.870 --> 00:15:10.580 And then click in 243 00:15:10.860 --> 00:15:12.300 That's a page 244 00:15:12.370 --> 00:15:14.040 To the link address 245 00:15:15.430 --> 00:15:17.060 After entering the link address 246 00:15:17.060 --> 00:15:18.400 We're going to do a search 247 00:15:18.400 --> 00:15:21.020 How to search accurately? 248 00:15:21.560 --> 00:15:25.960 We can use keywords to retrieve fields and search rules. 249 00:15:27.300 --> 00:15:30.000 We should probably have passed primary school. 250 00:15:30.120 --> 00:15:31.530 Just one is the Boolean operator 251 00:15:31.530 --> 00:15:32.800 One is the position operator. 252 00:15:32.800 --> 00:15:34.130 And there's a wildcard 253 00:15:35.090 --> 00:15:40.320 Some symbols like the signal question mark are used to construct the search words. 254 00:15:40.670 --> 00:15:42.490 Let's take a look at urbanization 255 00:15:42.960 --> 00:15:44.220 I used the theme 256 00:15:44.650 --> 00:15:45.730 This field 257 00:15:46.130 --> 00:15:47.640 You can also say the nomination. 258 00:15:47.890 --> 00:15:52.470 Because all I have to do is, for example, I just have to go back to my life. 259 00:15:52.840 --> 00:15:56.130 Mich, I'm gonna have to if the nomination doesn't show up. 260 00:15:56.130 --> 00:16:02.100 I don't want that it's like we're supposed to be type Z if it's a nomination 261 00:16:02.510 --> 00:16:04.760 I've done more than 9, 000 pieces. 262 00:16:04.960 --> 00:16:09.020 But now I use the theme, he can be more than 20, 000. 263 00:16:09.020 --> 00:16:11.250 So what is the principle of the subject? 264 00:16:11.320 --> 00:16:15.110 I was talking to the teacher here just after class. 265 00:16:16.270 --> 00:16:19.580 In some documents, it may not mention urbanization in the title. 266 00:16:19.710 --> 00:16:22.260 But it says in the abstract 267 00:16:23.370 --> 00:16:30.270 A certain method is in the field of urbanization, or a certain problem is the process of urbanization. 268 00:16:30.270 --> 00:16:33.820 An inevitable problem 269 00:16:35.140 --> 00:16:36.540 There is no word for urbanization at all. 270 00:16:36.540 --> 00:16:40.110 But it has the word urbanization in the abstract. 271 00:16:40.960 --> 00:16:43.560 Topic field 272 00:16:43.560 --> 00:16:45.740 Then this document will be cut out for you. 273 00:16:45.930 --> 00:16:47.280 So it will be more 274 00:16:47.280 --> 00:16:52.410 So if we're going to do something like what I just showed in the first class 275 00:16:52.410 --> 00:16:58.320 Is to scan the survey of research in this field. 276 00:16:58.880 --> 00:17:01.930 Well, you'd better have more literature. 277 00:17:02.110 --> 00:17:04.670 I hope we can check the comparison. 278 00:17:04.670 --> 00:17:08.020 In this case, the topic is usually used to search. 279 00:17:08.100 --> 00:17:10.870 Of course, if I don't want Zha Quan. 280 00:17:10.870 --> 00:17:13.270 I just need to find out exactly 281 00:17:13.270 --> 00:17:15.450 I'll try to find out. 282 00:17:15.450 --> 00:17:18.670 Things are relatively accurate. 283 00:17:20.120 --> 00:17:21.070 I'll just use the title 284 00:17:22.010 --> 00:17:24.780 In this case, it may be said that the topic did not mention. 285 00:17:24.800 --> 00:17:28.680 Perhaps he said that urbanization is not very long than not very much. 286 00:17:28.680 --> 00:17:32.200 Or urbanization is not its main content. 287 00:17:32.400 --> 00:17:37.410 I will put this topic, not in this field. 288 00:17:37.570 --> 00:17:39.060 I'll change it to this topic. 289 00:17:39.060 --> 00:17:40.160 That's all 290 00:17:43.720 --> 00:17:50.030 Then I said, this is more than 26, 000 articles I did this afternoon. 291 00:17:50.240 --> 00:17:56.690 So how to find the highly influential papers in this field? 292 00:17:56.940 --> 00:17:59.270 We were just talking about retrieval 293 00:17:59.270 --> 00:17:59.930 Accuracy 294 00:17:59.930 --> 00:18:02.870 One is a subject or title. 295 00:18:03.070 --> 00:18:05.630 There's another one we're going to do some hijacking 296 00:18:05.630 --> 00:18:08.140 Why am I here is a signal 297 00:18:09.550 --> 00:18:10.770 As I said earlier 298 00:18:10.770 --> 00:18:13.210 When we started the subject of urbanization 299 00:18:13.210 --> 00:18:17.340 Let's read everything first, what is urbanization? 300 00:18:17.340 --> 00:18:21.540 Then all the words related to urbanization are listed and put into the examination. 301 00:18:21.540 --> 00:18:24.390 But at last it was found that it could not be exhausted. 302 00:18:25.410 --> 00:18:32.820 And then we find out what's going on and what's going on is actually overlapping 303 00:18:33.110 --> 00:18:36.490 So in the end, after a lot of detours. 304 00:18:36.490 --> 00:18:39.990 Finally, it is certain that maybe it is the best. 305 00:18:39.990 --> 00:18:43.110 But there may be some changes. 306 00:18:43.110 --> 00:18:51.120 So it was after na did a hijack on the urbaa 307 00:18:51.120 --> 00:18:57.320 Because there is a minority of s or uc, this kind of different way of writing. 308 00:18:57.580 --> 00:19:02.590 So do such a hijack suit 309 00:19:03.020 --> 00:19:05.430 Can let us check more fully. 310 00:19:05.430 --> 00:19:08.000 Of course if I don't want this hijack 311 00:19:08.000 --> 00:19:10.670 I just want the word 312 00:19:10.710 --> 00:19:12.190 Then don't worry.
