We developed the three channel lidar system to measure stratospheric aerosols at the Gwangju Institute for Science and Technology (GIST), a suburban site in Republic of Korea. The system provides backscatter coefficient (${\beta}$) at 532 and 1064 nm as well as depolarization ratios (${\delta}$) at 532 nm ($2{\beta}+1{\delta}$) using the doubled Nd:YAG laser wavelength at 532 and 1064 nm. The lidar system is optimized to measure stratospheric aerosols such as volcanic ashes. This paper describes the details of the optical setup, data acquisition system, and analysis method. This study shows an example of measuring stratospheric aerosols emitted by the volcanic eruption which occurred in Mt. Nabro ($13.37^{\circ}$ N, $41.70^{\circ}$ E).

It has been said that Gwangjudream, nevertheless a free press, plays a role as a local press that it should be, in a situation that other local papers do not. This study aims to reveal the forces that influence the article production of Gwangjudream, and to examine the interrelations between them, through using the methods of participant observations and depth interviews. In this course, it is eventually purpose of providing more deep understandings on the present circumstances and problems of the local papers and having a chance to concern the concrete ways to enhance them. This study results in revealing the five forces that primarily influence the article production of Gwangjudream: 1) as a historical force, keeping the spirit of the first publication that look forward to playing a role as a local press that it sound be, 2) as an individual force, the habitus of its members that is critical of mainstream society and culture, 3) as an organizational force, non-hierarchical culture and the independence of the editorial rights, 4) as a habitual force, the deny of beat system, 5) as an economical force, the power of sponsors, financial poorness, and the competition for attracting subscribers. While the historical force and the individual force play a role as fundamental circumstances and the organizational force and the habitual force as practical circumstances for producing articles, they encourage to emerge the characteristics of the articles that are related to citizens' everyday life and reflect locality, and criticize and keep an eye on government and other public offices. However, the economical force provides the circumstances that weaken the characteristics of Gwangjudream. The results of this study question the perspective to overly regard it as coming from their economical weakness that the local newspaper do not play a role as a local press that it should be.

To this day, a number of quantitative analytical methods have been employed in clarifying regional characteristics in the discipline of geography. This paper attempted, as a part of application of those quantitative analyses, to make clear the urban functions and consequently the urban characteristics statistically by adopting newly-introduced CHAID, a sort of discriminant analyis technique. The processing of data was sonducted in two phases. To begin with, the urban functions were classified after designating twenty cities - the population of each city counting 250, 000 or more - as predictor variable, and at the same time four major urban functions like administration, marketing, finance and production as response variable. And then, preeminent functions of individual region were discriminated and concurrently classified by treating the remaining traffic, education, medicare, culture and transportation functions as predictor variable, and the following five regions as response variable: Metropolitan Seoul Area. Pusan region, Taegu region, Kwangju region and Chungcheong region. According to the result of this analysis, marketing and administration are emereed as meaningful functions in Seoul and Taegu respectively. As for the finance function only Pusan and Pucheon can be discriminated. Seoul, Pusan and Seongnam reveal their dominancy in production function. To take a look at the result of the latter analysis, the Metropolitan Seoul area shows, among other functions, strong traffic and finance functions. When it comes fo Pusan region, adminstration, education and finance functions are recorded as a leading ones, and Taegu region is preferable in education, medicare and transportation functions. In case of Kwangju region adminstration, production and education functions are discriminated from any other functions. Chungcheong region shows similar aspect with only traffic function replacing the production function of Kwangju region. Based on aforementioned anlysis, it can be said that the CHAID technique, which is capable of processing large amount of categorical data and, by presenting its outcome in the form of dendrogram, facilitates the interpretation work, is an effective, meaningful means to classify and discriminate certain geographical regions and their characteristics.

Objectives This study is designed to evaluate the safety of palmul-tang soft extract in healthy male volunteers. Methods Twelve healthy male volunteers were recruited. And this study was conducted in a single center. As a result of the laboratory test, the safety was evaluated by collecting vital signs of volunteers. Twelve subjects were assigned by serial number according to the registration order. For safety evaluation, blood samples were collected and vital signs were checked four times throughout the test period, including screening, pre-administration, post-administration (after 48 hours) and post-administration (after 7 days). The difference in variables was summarized as the mean±standard deviation. The normality was performed using Kolmogorov-Smirnov and Shapiro-Wilk test. If normality is satisfied, a paired t-test is applied. Otherwise, the Wilcoxon sign rank test, which is a nonparametric method, is applied. The significance was p<0.05. The incidence of all side effects is expressed as a percentage. Results In the case of red blood cell, hemoglobin, and hematocrit values, the result of normality test of variables for the difference value before and after administration is significant level p<0.05. However, all laboratory test values before and after administration did not deviate from the normal range. Also the deviations in the normal range could not be seen as significance related to this clinical trial. And no side effects related to clinical trial drugs were observed. Conclusions The soft extract of palmul-tang was considered safe for healthy male volunteers.

This study predicts the means sharing ratio of the urban air transportation (UAM) when the VertiHub of the UAM in the southern western part is built at Songjeong Station in Gwanju. Based on Monte Carlo simulation of the utility function and means selection logit model for each means of transportation, our findings indicate an average mode share of 0.95%, with a variability range from 0.07% to 4.7%. Moreover, 95% of the simulation outcomes fall below a 2.02% mode share. Sensitivity analysis, conducted via Tornado Plot, highlights that the mode share is principally influenced by factors such as the unit fare, cost parameter, basic fare, and the time required for takeoff and landing. Notably, a negative correlation exists for unit fare, basic fare, and takeoff and landing time, suggesting the necessity of setting an appropriate level of fair to enhance UAM utilization.

도서관을 찾는 사람은 늘고 있으나, 읽는 책은 베스트셀러에 한정됐다. <출판저널>이 '독서의 달'을 맞아 전국 도서관 사서들을 대상으로 도서관 이용자의 독서경향에 대해 설문조사한 결과, 교육환경의 개선과 IMF여파로 이용자 수는 증가했으나, 도서구입예산과 독서 프로그램 부족으로 도서관에서 이뤄지는 독서는 문학 등 특정 분야에 편중되고 있다는 사실이 밝혀졌다. 학생들의 대출 건수는 꾸준히 늘어 강화군립도서관만 하더라도 전체 대출의 55%가 학생이다. 다른 도서관도 사정은 같아 학생들이 하교하는 오후 시간대에 가장 이용률이 높다. 최근에는 실직인구가 늘면서 성인 남자의 이용률도 높아졌다. 오미순 사서(해운대도서관)는 "IMF 여파로 취업.창업 관련서의 이용률이 늘고 있으며 그 이용자 대부분은 성인"이라고 밝혔고 성은정 사서(부여도서관) 역시 "IMF사태 이후, 성인 남자들의 이용률이 높다"고 응답했다. 하지만 문제는 도서관이 보유한 책이 베스트셀러에 국한돼 다양한 독서가 이뤄지지 않는다는 점. 조사결과, 이용자들은 <아리랑>, <하늘이여 땅이여>, <남자의 향기>, <토지> 등을 많이 찾는 것으로 집계됐다. 심지어는 로맨스소설이나 무협소설이 청소년들의 읽을거리로 제공되는 실정. 사정은 특수도서관도 마찬가지다. 어린이도서관의 경우, 어린이.성인 모두 문학류를 많이 찾고 점자도서관의 경우, 전체대출 중 80%가 소설류다. 구본일 사서(강화도서관)는 "예산이 부족해 이용자들이 많이 찾는 베스트셀러를 중심으로 구입할 수밖에 없다"고 밝히고 "다양한 책을 갖출 수 있도록 도서구입비 확충이 시급하다"고 주장했다. 또 알맞은 독서 프로그램이 없는 점도 이용자들의 베스트셀러 편중현상에 한몫을 담당했다. 진재호 사서(광주도서관)는 "과거보다 독서생활화가 고조됐지만, 양서를 읽는 독서문화의 부족"을, 김선연 사서(어린이도서관)는 "유아시절부터 성인까지 자연스레 고전을 읽게 하는 제도적 장치의 확충"을 지적했다. 한편 월평균 대출권수는 대도시 지역의 경우 11,000-45,000권, 그 외 지역은 1,600-6,000권, 특수도서관은 어린이도서관이 55,000권, 전화나 우편으로 대출하는 점자도서관이 650권이다. 관내열람만 허용되는 사회과학도서관은 월평균 이용자가 7,676명으로 대학생.대학원생.교수 등이 전체의 68%를 차지한다.

The present article focuses on the cultural arts, the role and functions of people as intermediate to carry out the revitalization of memory. Most of the basic cultural activities and events sparked from the cardinal point of the democratization of Gwangju and the interwoven relationships this created. In other words, the events leading to Gwangju democratization movement have derived from democratic culture and art and they contributed to change and influence South Korea's revolutionary movements. As far as clarifying the concept of culture is concerned, the idea of culture is too wide to encompass it so we aim to narrow it down to the special events of 5.18 democratization movements which launched the national transformation of the cultural stage and the development of democracy in South Korea. Through this, the movement of popular culture and popular arts fostered the revolution of society. Moreover, the value of the 5.18 movement for democratization stems from democracy, human rights, the universal value of peace and so many efforts were made by popular artists until it became upgraded as a national commemoration day. Raising the people's awareness that culture could change the course of history is still necessary so that popular art and culture play a central role in people's lives. In order to fulfill the people's inherent hope it is necessary to promote aesthetic values and a continuous revolution in societal practices.

Objectives This study is designed to evaluate the safety of Bojungikgi-tang soft extract in healthy male volunteers. Methods 12 healthy male volunteers were recruited and this study was carried out by a single center. Laboratory test results, vital signs of the volunteers were collected to evaluate safety. According to registration order, the 12 subjects were allocated by serial number. To evaluate safety, blood samples were taken and vital signs were checked 4 times - screening, pre administration, post administration and follow up-during the whole trial. The difference between pre (before medication [0 hr]) and post-administration (after medication [48 hr]) variables was summarized as mean±standard deviation. The normality test was performed using the Kolmogorov-Smirnov test and Shapiro-Wilk test. When the normality is satisfied, the paired t-test is applied. Otherwise, the non-parametric method, Wilcoxon signed rank test is applied. The significance level was p<0.05. The incidence of all adverse effects are shown in percentage. Results In the case of red blood cell, hemoglobin, hematocrit, lymphocytes, neutrophils, protein, γ-glutamyl transpeptidase values, the normality test result of the variable for the difference value before and after the dosing has a significance level <0.05. But most of values did not deviate from the normal range, and the deviation from the normal range could not be regarded as the significance associated with this clinical trial. And adverse event wasn't observed associated with the clinical trial drug. Conclusions Bojungikgi-tang soft extract were considered to be safe for healthy male volunteers.
