가물치의 위장관 내분비세포의 부위별 분포 및 출현빈도를 면역조직화학적으로 관찰하였던 바, secretin 면역반응세포들은 위의 분문부와 위저부의 상피 또는 장선부에서 소수로 출현하였다. Motilin과 GRP 면역반응세포는 장의 원위부와 위저부의 상피에서 극소수로, PYY 면역반응세포들은 유문맹낭부위와 장의 근위부에서 소수 또는 극소수로 각각 관찰되었다. Substance P 면역반응세포들은 위저부에서 장의 원위부에 걸쳐 소수 내지는 비교적 다수의 출현빈도를 보였으며 또한 장의 원위부 고유층에서는 신경세포가 양성반응을 보였다. 그러나 neurotensin, met-Enk, GIP 면역반응세포들은 전장관에서 관찰할 수 없었다.

Okso, Keun Seob($1671\sim1759$) was descended from a noble family of Noreun(노론) and learned from his uncle, Keun Sang-ha who is a disciple of Song Si-Yeol, Kim Chang-hyeub and Kim Chang-heub. His $\lceil$Oksoko$\rfloor$ remains in the form of a transcription or a lithographic printing, and documents on 'Hakchangeui' are recorded in jabeui(잡의), Euijedogi(의제도기), which is a part of it. He left Seoul in 1714, settled in Chungpung, journeyed to many places, including the Hwang river area and Jecheon and led a literary and artistic life as Sadaebu(사대부), which was written in a collection of his works where the record about 'Hakchangeui', the most suitable clothes for the life of a retired scholar remains today to express one part of his life. This study introduces data about Hakchangeui written in $\lceil$Oksoko$\rfloor$, pursues the reason why Okso, Keun Seob told about it and intends to embody the figure of Hakchangeui based on the system, measure, material, and sewing method according to the records in a collection. Hakchaneui described in $\lceil$Oksoko$\rfloor$ reveals a structure that is different from old Hakchaneui, showing characteristics like the following. It is a Sadaebu's costume for field amusement in which the length of a former part is longer than that of a later part and the side seam of a garment rips. Black Yeon is attached to the white texture. Yeon widths of Git(collar), Sugu and Gil are varied, respectively. Yeon's figure attached to Gil and Somaejindong is a mountain. Git is Bangryeong and link parts between Git and Gil is connected with Sangchim. This Hakchangeui is considered to playas a gown because it has no string or support to adjust his dress. Especially we can identify that Hwayanggun(화양건) was used in this Hakchangeui.

The regional distributions and relative frequencies of the gastrointestinal endocrine cells in the bean goose (Anser fabalis Latham) were investigated by immunohistochemical methods using bovine Sp-1/chromogranin (CG), serotonin, gastrin, cholecystokinin (CCK)-8, somatostatin and glucagon antisera. BCG-immunoreactive cells were widespread throughout the gastrointestinal tract (GIT) with moderated frequencies except for the gizzard and proventriculus which were a few frequencies. Serotonin-immunoreactive cells were detected throughout the GIT except for the proventriculus and gizzard. These cells were observed in the pylorus with rare frequencies but numerous cells were detected in the intestinal tract. Gastrin-immunoreactive cells were restricted to the gizzard, pylorus and duodenum. These cells were most predominant in the pylorus and a few or rare in the gizzard and duodenum, respectively. CCK-8-immunoreactive cells were observed from the gizzard to ileum. The highest frequencies of endocrine cells were observed in the duodenum. These cells were increased from the gizzard to duodenum but thereafter decreased. Somatostatin-immunoreactive cells were detected in the GIT except for the large intestine. In the proventriculus and pylorus, numerous immunoreactive cells were demonstrated but a few cells were present in the other regions. Glucagon cells were observed in the gizzard, pylorus, ileum, colon and rectum with a few or moderated numbers.

Background: Latent tuberculosis (TB) infection among TB contacts is diagnosed using plain chest radiography and interferon-gamma release assays (IGRAs). However, plain chest radiographs often miss active TB, and the results of IGRA could fluctuate over time. The purpose of this study was to elucidate changes in the results of the serial IGRAs and in the findings of the serial submillisievert chest computed tomography (CT) scans among the close contacts of active pulmonary TB patients. Methods: Patients age 20 or older with active pulmonary TB and their close contacts were invited to participate in this study. Two types of IGRA (QuantiFERON-TB Gold In-Tube assay [QFT-GIT] and the T-SPOT.TB test [T-SPOT]) and submillisievert chest CT scanning were performed at baseline and at 3 and 12 months after enrollment. Results: In total, 19 close contacts participated in this study. One was diagnosed with active pulmonary TB and was excluded from further analysis. At baseline, four of 18 contacts (22.2%) showed positive results for QFT-GIT and T-SPOT; there were no discordant results. During the follow-up, transient and permanent positive or negative conversions and discordant results between the two types of IGRAs were observed in some patients. Among the 17 contacts who underwent submillisievert chest CT scanning, calcified nodules were identified in seven (41.2%), noncalcified nodules in 14 (82.4%), and bronchiectasis in four (23.5%). Some nodules disappeared over time. Conclusion: The results of the QFT-GIT and T-SPOT assays and the CT images may change during 1 year of observation of close contacts of the active TB patients.

한국산 두더지의 위장관 점막과 췌장에 분포하는 내분비세포들의 분포와 출현빈도 및 종류를 알아보기 위하여 면역조직화학적으로 관찰하였던 바, 5-HT 면역반응세포는 극소수내지 중등도의 빈도로 전 장관에 고루 분포하였다. Glucagon 면역반응세포는 대장에 국한하여 출현하였다. 또 bovine CG, BPP 및 somatostatin 면역반응세포들은 각각 십이지장, 공장 그리고 위저부를 제외한 전 장관에 다양한 빈도로 고루 분포하였다. Gas/CCK 면역반응세포는 유문부와 소장에서만 다수 그리고 극소수로 관찰되었으나, insulin 면역반응세포는 전 장관에서 관찰할 수 없었다. 한편 췌도의 주변부에서는 glucagon, somatostatin과 BPP 면역반응세포들이, 중심부에서는 insulin 면역반응세포가 높은 빈도로 동정되었으며 또한 외분비에서는 이들 면역반응세포들이 단독 또는 소수의 집단으로 출현하였다. 이상의 결과로써 두더지의 소화관내분비세포의 분포패턴는 고슴도치의 그것과 유사하였으나 십이지장에서 세포의 종류와 출현빈도가 낮은 것을 알 수 있었다.

Korean Chinese, immigrants to China, have developed their own traditional costume culture. This paper aims to analyze the traditional costume culture of the Korean Chinese and to provide data for posterity. The research methods are literature research, survey research, and analysis research. The results are as follows: According to the changes over generations, the top of women's Hanbok has changed in length as has the jeogori (jacket), the git (collar), and the gooreum (breast-tie). The width of the git, dong-jeong (thin white cloth-covered paper collar of Hanbok), the sleeve, and gooreum have also changed. The git and the barae (the curve part of the sleeve) have changed from straight patterns to curves. The skirt had changed in wrinkles arrangement, length, and silhouette. The men's Hanbok jeogori and sleeves were lengthened; the pants became wider and were lengthened, and the collar also became curved. The vest has not changed and the du-ru-ma-gi (coat) that once disappeared is being worn again; the bae-ja (vest) and magoja (over-jacket) are worn frequently in modern times. The garments mainly used natural fiber until the development of synthetic fibers, but the treand has been the use of luxurious natural fibers in modern times. The initial color pattern was achromatic, but that changed with the appearance of synthetic fibers, and nowadays it is mainly the garmetnt can display a variety of colors. In addition, hairstyles and shoes have been eveolved from traditional to modern styles.

This study aims to identify the perception of New-Hanbok one-piece dresses that female consumers have purchased and to analyze the design preference based on design types and brands. Analysis was conducted on New-Hanbok brand websites, and additional research was carried out through a survey of 402 women in their 20s and older. The survey consisted of 36 questions, which were divided into categories including pattern, color, material, and recognition of the one-piece dress. The research results are as follows. First, the preferred design form of the New-Hanbok one-piece dress was long length, medium fit, princess line, round git, rectangular git, regular width git, V neckline, regular width dongjeong, front closing with a wide overlap of the chest are a, narrow goreum, a skirt part with moderate crease spacing and number of pleats, A-line skirt silhouette, long and narrow sleeves, diagonal shoulder line, and a cuff at the end of each sleeve. Second, the preferred colors of the New-Hanbok one-piece dress were bright, neutral, or light and were predominately monochromatic Third, the preferred fabric conveyed a contemporary atmosphere through its print pattern. The most favored fabric material was cotton. Through this study, more systematic design development research should be carried out focusing on the current situation and identifying problems, thereby improving traditional culture.
