  • Focusing on the recently announced "KOSPI 200 ESG Index," this study intends to examine whether the "KOSPI 200 ESG Index" has any relevance to stock prices. Specifically, it was empirically analyzed whether companies included in the KOSPI 200 ESG index showed average abnormal return and cumulative average abnormal return of stock prices due to incorporation into the index. As for the research method, the case study was conducted using the return by the market model using the coefficient estimated by the OLS for the normal expected return. The study results are summarized as follows. First, the initial incorporation of a company into the KOSPI 200 ESG index showed significant positive(+) average abnormal return and cumulative average abnormal return. Second, the incorporation of a company into the KOSPI 200 ESG index showed significant positive(+) average abnormal return and cumulative average abnormal return. Through this study, it was confirmed that investors in the market are aware of ESG indicators as non-financial information, not just financial information. In addition, it can be said that the contribution of this study to the fact that investors perceive ESG index as information for investment. This study differs in that it uses the latest ESG index, but at the same time, it has limitations in that the study period is short and the study sample is limited.

  • While reserve forces play a critical role in modern warfare, the primary focus on reserve forces has been on men. Women's reserve forces have received little attention. The purpose of this study is to examine the need to increase the number of women in the reserve and the impact of increasing the number of women on active duty. The reasons for the need for women in the military are the decrease in the resources of the reserve force as well as the regular force due to the decrease in population, the development of fields where women can perform missions with advantages due to the changing patterns of warfare, and the changing situation of gender equality and the increasing role of women in society. However, it is currently optional, not mandatory, for female veterans to join the Reserve. The number of cadres entering the reserve may decrease as the number of active-duty women increases. Using a 2018 estimate of 13.9 percent of women transitioning to the Reserve, 194 of the 1,402 projected transitioning women in '27 will transition to the Reserve. This leaves an estimated shortfall of 1,208 reserve officers and NCO. This suggests that the policy of increasing the number of women on active duty could have a significant impact on the reserve force in the future, and further policy research is needed.

  • 본 연구에서는 한국주식시장의 대표적 주가지수인 KOSPI 200 진입기업과 제외기업의 주가 행태에 어떤 변화가 있는지를 분석하였다. 1994년 6월 이후부터 1999년 정기변경때까지의 기간에 KOSPI 200에 새로 진입한 종목과 제외된 종목을 검증표본으로 하고 이와 유사한 특성을 가지는 기업들을 대응표본으로 삼아 두 집단간에 나타나는 비정상수익률 및 누적비정상수익률의 특성과 비정상수익률과 비정상거래량간의 관계를 비교 분석하였다. 사건일의 비정상수익률과 사건기간동안의 누적비정상수익룰에 대한 분석결과는 KOSPI 200에 새로 포함되거나 제외되는 종목의 주가행태에 뚜렷한 변화가 있다는 결과를 보여주지는 못하고 있다. 그러나 일부 표본의 분석결과는 KOSPI 200에 새로 진입하거나 제외되는 정보가 공시일 이전에 시장에 반영되는 모습을 보여주며, 외환위기 이후기간에 발생한 정기변경진입종목에 나타난 주가행태 변화와 주가변동과 거래량 변동간의 관계는 일부 가격압박가설로 설명될 수 있음을 보여준다. 그러나 본 연구의 분석결과는 지수 신규편입 종목들이 펀드에 신규로 편입되는 과정에서 거래량이 증가해 초과수익이 발생한다는 기존의 가격압박가설의 내용을 충분히 지지하지는 못하고 있다.

  • LiDAR 자료를 이용한 지형 및 공간 정보 자료를 구축하기 위해서는 LiDAR 자료의 오차 보정, 건물영역 및 지면 분리, 건물 및 지형의 재구성 등의 과정이 필요하다. 그 중에서 건물영역 분리 과정은 막대한 양의 LiDAR 자료에 대한 직, 간접적인 처리를 필요로 하며 결과물의 품질에도 큰 영향을 미친다. 본 연구에서는 LiDAR 자료로부터 건물 영역을 분리해 내기 위하여 LiDAR 원 자료를 그대로 활용하는 방식을 제안하였다. 항공레이저측량은 스캔라인을 따라 취득되는 포인트정보를 순서대로 저장하여 제공하므로 LiDAR 자료로부터 연속적으로 입력되는 포인트들은 서로 인접할 가능성이 높다. 이와 같은 특성을 이용하여 유사한 고도 값을 갖는 인접 포인트들로 클래스를 형성하고 새로운 포인트가 속할 클래스를 검색하여 편입시킴으로써 건물영역을 분리해 낸다. 아울러 각 건물 클래스에 대한 레이블링도 자동적으로 수행하며 새로운 포인트가 편입될 클래스를 검색하는 방법에 있어서도, 클래스의 검색 순서와 클래스의 자료 구조를 효율적으로 운용함으로써 성능 향상을 도모하였다.

  • 성계편입전의 체중측정은 어떤 사료를 얼마나 급여할 것인가를 결정하여 줄 수 있으므로 정확한 기록은 올바른 산란계관리의 지침과 예고서가 될 수 있다. 또한 체중에 따라서 사료의 제한급이 여부나 제한량을 결정하는 것이 제일 확실한 방법이다.

  • Recently, many civil appeals have been occurred in land management work because of discord between cadastral records and actual land use pattern. it is important to select parcels for land alternation exactly using land information and to evaluate compensation cost according to scenarios for advancing this problem. This study operated GIS spatial overlay based on serial cadastral maps and actual-width of the road and analyzed the number and area of the parcels for land alternation by the land classification and ownership applying fuzzy membership function according to occupation ratio to road. Also compensation cost was calculated according to scenarios using individual public land price information of the parcels for land alternation and was arranged by district as Eup and Myeon according to land classification and ownership. This study can efficiently support the work of the parcels for land alternation complying with the financial condition of local government, by supplying compensation cost according to scenarios to the parcels of land alternation by district as Eup and Myeon.

  • The long-term effects of vegetable and animal high fat diet on the lipid metabolism were investigated in male weaning rats. The rats were fed one of four semipurified diet ad libitum : control diet supplied 12% of calories as fat(control group), low fat diet supplied 3% of calories as fat (3% F group), 45% corn oil diet supplied 45% calories from corn oil (45% C group) and 45% butte. fat diet supplied 45% calories from butter fat (45 % B group). Incorporation of $acetate-1-^{14}C$ into lipid of liver, serum and adipose tissue as well as exhalation of $^{14}CO_{2}$ from $acetate-1-^{14}C$ were observed in rats fed for 4,8 and 12 weeks. The weigh of epididymal adipose tissue of rats, fed 45% corn oil and 45% butter fat . from 4 weeks to 8 weeks were higher, but not different at 12 weeks, compared with those of control group. The weight of abdominal adipose tissue appeared to be similar to those of epididymal adipose tissue. Incorporations of $acetate-1-^{14}C$ into lipid of liver were remarkably decreased in high fat diet groups, especially in 45% C group, but in 3% F group were increased more than those of control group. Incorporations of $acetate-1-^{14}C$ into epididymal adipose tissue in 3% F, 45% C and 45% B group at 8 weeks were remarkably increased but not different at 12 weeks, compared with those of control group. The incorporation of {acetate-1-}^{14}C into abdominal adipose tissue appeared to be similar to those of epididymal adipose tissue. Incorporations of $acetate-1-^{14}C$ into lipid of serum in 45% C and 45% B group were reduced reasonably at 4 and 8 weeks of diet as compared with those of control group. Exhalation of $^{14}CO_{2}$ was increased to maximum level at 10 minutes after injection of $acetate-1-^{14}C$. Expiration of $^{14}CO_{2}$ in 45% C and 45% B group were higher than those in 3% F and control group for initial 5 minutes after injection, but expirations of $^{14}CO_{2}$ did not have significant difference among groups of diet since 10 minutes.
