Korean commercial-organized girl groups were remarkable in the late 1990's. However, by the late 2000's, girl groups had an even more profound effect on Korean popular music compare to past influences. This study aimed to analyze the social-cultural meaning of the changing appearance of girl group between the first and second-generations. For this purpose, this study analyzed media image and text, based on a social-cultural context, about 13 girl groups. The results are as follows. First, while the first -generation girl group tended to maintain girlish/sexy images trying to the male desire, the second -generation girl group strategically showed various sexual identities such as femininity, masculinity, masculinity and androgyny along with contextual sexual images. The reason why girl groups increased the number of strategic images featuring various sexual identities was in order to appeal to a wide, diverse audience. Second, the second generation girl groups had - slim bodies with great athleticism, basically due to trainee system. Because of this, their semiotic body images have been commercially used to promote the consumption. Third, the second generation girl groups - were the bigger stars than first generation girl groups - because the members worked in many different fields. Therefore, the group members' images were successful consumed directly and then reproduced symbolically. Fourth, each member of the second -generation girl groups characterized by appearing in diverse, yet familiar images, through various media sources. Although the intention of this was to have recognition and popularity, it became difficult for them to change their image once one particular image was deemed popular.

Four truncation selection schemes (SSs) were framed to predict and compare the age structures and genetic responses under the influence of various factor employing the scheme-specific algorithms. Two paths of selection, sires (bulls' sires) and dams (bulls' dams) to breed young bulls were considered. Among variable factors, four levels (0.3, 0.5, 0.7, 0.9) of precision of evaluation, five levels (0.0, 0.05, 0.10, 0.15, 0.20 genetic standard deviation) of genetic differences among age classes and 4 levels of proportions selected (for bulls' sire, 0.05, 0.10, 0.125, 0.25, and for bulls' dams 0.02, 0.04, 0.05, and 0.10) contemplated on both paths of selection. The number of age classes for bulls' dams and bulls' sires were 4 or 8 and 2 or 4, respectively. The stayability across age classes for bulls' dams was assumed to be 0.80 or 0.60. The candidates for selection for bulls' sires were equally distributed (0.5 or 0.25) across the age classes. The SS1 (selection on same proportions as candidates' distribution) revealed longest generation lengths and lowest yearly genetic responses. The average ages were youngest and yearly genetic responses were highest in SS4 (selection at each age-specific truncation point with the same average genetic superiority of selected parents across the ages) and followed by SS3 (selection at each agespecific truncation point with same predicted genetic values) and SS2 (selection at common truncation point on phenotypic values) in a population with overlapping generations. The results revealed the importance of choosing suitable selection scheme to acquire maximum yearly genetic responses especially when the genetic differences among age classes are large and the precision of evaluation is relatively low.

Objectives : This paper aims to lay out the meaning of Gongjindan, its indications and mechanisms based on relevant contents in the 『Donguibogam』, for better clinical application. Methods : First, Gongjindan related contents were searched in the medical classics database. Next, contents from the 『Shizhaibaiyixuanfang』 and the 『Donguibogam』 were analyzed. Finally, the properties of the Gongjindan ingredients were examined based on the 『Donguibogam』 and the 『Zhongyaodacidian』. Results & Conclusions : Examination of its indications according to the 『Donguibogam』 in terms of applicable age and viscera/bowels, Gongjindan could be applied to children with constitutional insufficiency and elder generations, but it could not be said to be most appropriate for older generations. In regards to viscera/bowels, Gongjindan sends water upwards into fire in the water-rising-fire-descending mechanism, which makes it applicable to symptoms of anxiety and fear by tonifying the consumed Jing and Blood caused by Liver deficiency. To summarize, those who would most benefit from Gongjindan are young adults in weak, fearful and lethargic conditions.

논 생태계 서식 생물을 장기적으로 모니터링하여 기후변화의 영향을 평가하기 위한 기초 연구로 잔물땡땡이의 발육단계별 온도발육모형을 선정하고 생태적 매개변수(유효적산온도, 발육한계온도, 발육최적온도, 발육최고온도)를 추정하였다. 선정된 온도발육모형을 이용하여 위도별 4 지역(철원, 당진, 부안, 해남)에서 발생하는 잔물땡땡이의 세대 수를 각 지역의 일 평균기온을 사용하여 예측하였다. 실험온도 구간(18~30℃)에서는 모든 성장단계에서, 발육속도가 온도에 따라 선형적으로 증가하였고 모형 사이의 적합성은 유의한 차이가 없었다. 하지만 발육최적온도와 달리 발육한계온도는 모형별로 상당한 차이를 보였다. 잔물땡땡이는 고위도인 철원에서 3.6 세대가 발생하지만 다른 지역에서는 4.3 세대가 발생하는 것으로 예측되었다. 본 연구의 결과는 기후변화에 따른 생물계절 변동 및 논 생태계 생물다양성 보전 연구의 기초자료로 활용될 것으로 보인다.

2001년 이후 2005년까지 북측의 씨감자 생산은 남북 협력으로 순조롭게 진행되어 일부는 이미 3급종자(G3)까지 공급되어 증식되고 있는 실정이다. 특히 씨감자 생산 체계의 상위단계인 조직 배양과 양액씨감자(G0) 생산에서는 성공적이었으며, 다음 단계인 1급(G1)$\sim$4급종자(G4)를 어떻게 무병, 격리 조건에서 감염율을 적게 유지, 증식, 관리하느냐에 달려 있다고 해도 과언이 아닐 것이다. 벌써 상위단게 씨감자 생산의 효과가 나타나기 시작하고 있어, 특히 남북한의 지속적인 협력이 절실하다고 할 수 있다.

Historically, white clothes have been passed down through the generations as the symbol of the Korean people. This study was motivated after coming across a text written by Lee Ok(李鈺, 1760~1815), a writer during the Joseon dynasty. Lee wrote that "Koreans mostly wear blue clothes." This raised questions regarding the wearing practice of the white clothes at the time of King Jeongjo's reign(1776~1800), and led to further studies on the matter. The results show that discussions were held about changing the color of the government official's changui(氅衣) from white to blue. An order was also given replacing white boots with black boots. Therefore, it is supposed that blue clothes phenomenon was influenced from the blue changui policy. However, this change was temporary as later generations wore preferred white with the exception being women's skirts. Women preferred blue skirts to white skirts for a long period. Detailed analysis of the white changui showed that people were burdened by high dyeing costs, and this was a big factor as studies indicated a large gap in wealth disparity. In a society that put funeral and ancestral rites as one of its priorities, the white clothes could have been favored due to its multi-functional use. Also, the noblemen who set importance on Gija(箕子) Joseon connected white clothes custom to Gija. This connotes that the reason for wearing white clothes differed depending on the class. And as white clothes were widely worn, people developed different ways of wearing the clothes for aesthetic purposes.

본 연구는 간편 결제 서비스의 세대 간의 사용자 경험 평가를 위한 연구이다. 현 사회의 핀테크 시장은 빠른 성장세로 다양한 간편 결제서비스가 출시가 되고 있다. 이에 따라 간편 결제서비스를 사용하는 과정에서 연령대별로 사용성과 접근성에 차이가 있으므로 세대 간의 견해 차이에 따른 사용자 경험 평가 연구 필요하다. 다양한 연령대 대상으로 피터 모빌(Peter Morville)의 허니콤 모델(Honeycomb Model)를 기반으로 설문조사와 심층 인터뷰를 진행하고 통계적으로 분석한 후 4가지의 간편 결제서비스의 발전 방안을 제시하였다. 연구 결과 간편 결제 서비스는 연령대가 높을수록 다양한 간편 결제 서비스를 사용하는 것보다 주로 사용하는 주거래 카드사의 간편 결제 서비스 혹은 자주 사용하여 학습된 간편 결제 서비스를 일부 한정하여 사용한다는 것을 알 수 있었다. 이 연구는 연령대에 따른 결제 애플리케이션 기초 연구에 도움이 될 것으로 기대한다.

The porcine MHC (Major Histocompatibility Complex), encoding the SLA (Swine Leukocyte Antigen) genes, is one of the most significant regions associated with immune rejection in relation to transplantation. In this study, three SLA class I (SLA-1, SLA-3, SLA-2) loci and three SLA class II (DRB1, DQB1, DQA) loci were investigated in the previously unidentified Korean native pig (KNP) population that was closely inbred in the Livestock Technology Research Station in Cheongyang, Korea. Total thirteen KNPs from four generations were genotyped for the SLA alleles and haplotypes were investigated using PCR-SSP (Sequence-Specific Primer) method. The results showed that all of these KNPs had Lr-56.30/56.30 homozygous haplotype, indicating high level of inbreeding in the SLA genes. The inbreeding status of these animals was also investigated using microsatellite (MS) markers. From the 50 MS markers investigated, 17 MS markers were fixed in all generations and the fixed alleles are increased as 26 loci for the fourth generation. Two MS markers, S0069 and SW173, were heterozygous for all the animals tested. Observed and expected heterozygosities were calculated and the average inbreeding coefficients for each generation were also calculated. In the fourth generation, the average inbreeding coefficients was 0.732 and this may increase with further inbreeding process. Analysis of the SLA haplotypes and MS alleles can give important information for breeding the pigs for xenotransplantation studies.
