섬진강 유역(경남 하동군)산 황어(Tribelodon taczanowskii)로부터 Metagonimus속 피낭유충을 다수 검출하고 실험적으로 흰쥐와 햄스터에 감염시킨 후 소장으로부터 성충을 얻어 관찰한 바 Saito(1984)의 분류에 따라 Metagonimus Yokogawa형 (M. yokogawai), Miyata형 및 Koga형 등 3가지로 나눌 수 있었다. 실험감염 결과, 흰쥐 4마리 및 햄스터 4마리로부터 Metagonimus 충체 총 1,624마리를 회수하였고 그 중 Yokogawa형은 820마리, Miynta형은 688마리, Koga형은 46마리이었다. 나머지 충체 70마리는 유형을 결정하기 어려웠다. Yokgawa형과 Miyata형의 주요 감별정은 두 고환의 위치, 자궁관의 분포 및 충란의 크기 등이었고, Miyata형과 Koga형의 감별점은 두 고환의 위치, 난환선의 분포, 충란의 크기 등이었다. 이들 유형 특히 Miyata 형의 별종 가능성에 대해서는 많은 증거가 얻어질 때까지 이를 유보해야 할 것으로 생각되고, Koga형은 중간숙주의 차이 이외에는 형태학적으로 Takahashi형 (M. takahashii)과 전혀 차이가 인정되지 않으므로 이와 동일한 것으로 취급하는 것이 옳을 것으로 판단되었다. 이상의 결과로 섬진강산 황어에는 3가지 유형의 Metagonimus가 피낭하고 있음을 확인하였다.

A brassier supports and protects breasts and makes a better shape of the upper half of the body through shaping breasts. A brassier, therefore, is recognized as the key underwear for female. Recently, the distribution structure and channels of the brassiere industry is diversified from conventional type of markets to department stores, convenience stores, and internet shopping mall. Studies on the sales of brassieres via internet, however, is not sufficient even though the market size has been dramatically increased thursdays. The study on the size structure (including the size and the materials fabric of brassieres circulating via internet) is especially rare. Therefore, this study tries to comply with increasing requests of consumers through comparing brassier brands on internet. In depth, this study compares cases of Korea and Japan in terms of availability of website on sales, quality indication like materials and functions, and size. The results indicated that there were three companies in Korea which run a website and make a sale through a website. All three Japanese companies operate a website and make sales on a website as well. In terms of size, Korean companies diversify their size of products in two ways. It varies from A cup to D cup based on cup size, and 65 to 100 according to its entire size. On the other hand, Japanese companies use AA, A to I to measure cup size, and 65 to 100 for entire size.

The purpose of this study was to provide with the useful fundamental data by developing the appearl sizing system according to body types for the Women's Wear Specifications(GB/T 1335.2-1997), National Standards of People's Republic of China. Thus, it was to improve of the garment fit and coverage rate for the apparel production assortment and stock of exporting domestic clothing to China. For this study, 581 female women aged in their twenties who lived in Beijing and Shanghai were selected for the development of the apparel sizing system who resident in Beijing and Shanghai in China. As for the method of this study was made three primary items(length, bust girth, waist girth) and seven secondary items. Data analysis were processed by SPSS WIN 10.0 Program was used. The research selected 3 major body measurements, such as stature, bust girth, waist girth and 7 secondary measurements to investigate the body features of the Chinese adult women. The data throughout the study were analyzed by using SPSS WIN version 10.0 S/W. The result were as follows: The clothes dimensions for upper and lower body and the coverage rate of body size that had the highest appearance ratio from the selected age group in 20's were: Y-type 160-84 155-64(5.9%) and the section 160cm 22.6%, A-type 160-80 160-62(39%) and the section 160cm 27.9%, B-type 155-80 155-66(6.2%) and the section 160cm 24.7%. The representative size codes of the Chinese adult women aged in their 20's were set for representing certain body dimensions such as 150-76A 150-60A(0.0%), 155-80A 155-64A(2.4%), 160-84A 160-68A(3.9%), 165-88A 165-72A(0.3%), 170-92A 170-76A(0.0%). The production coverage rates for the each representative size codes were S size the section 150cm 1.5%, M size the section 155cm 15.3%, L size the section 160cm 36.0%, XL size the section 165cm 29.7%, XXL size the section 170cm 11.4% that covered 93.9%.

Aerosol size distribution was determined using Anderson sampler for the anions( sulfate nitrate and chloride ) and TSP. Ionic species concentration and size distribution have been investigated in the daytime and nightime individually. Size classified samples were extracted with distilled water and analyzed for C $l^{[-10]}$ , N $O_3$$^{[-10]}$ and S $O_4$$^{2-}$, by ion chromatography. The size distribution of these ions and TSP was analyzed to investigate the seasonal and diurnal variation of concentrations as follows: (1)Size distribution of TSP showed bi- modal type in the daytime, but indicated tri-mode distribution in the nightime without any seasonal variation. (2)Sulfate concentrations were higher in fine- mode both in the daytime and nightime but fraction of sulfate was higher in coarse-mode during the Yellow Sand Period. (3)Nitrate and Chloride ions are dominant in fine-mode in winter while dominant in coarse-mode in the summer.

In this study, we consider the sample size determination problem for clustered count data with many zeros. In general, zero-inflated Poisson and binomial models are commonly used for zero-inflated data; however, in real data the assumptions that should be satisfied when using each model might be violated. We calculate the required sample size based on a discrete Weibull regression model that can handle both underdispersed and overdispersed data types. We use the Monte Carlo simulation to compute the required sample size. With our proposed method, a unified model with a low failure risk can be used to cope with the dispersed data type and handle data with many zeros, which appear in groups or clusters sharing a common variation source. A simulation study shows that our proposed method provides accurate results, revealing that the sample size is affected by the distribution skewness, covariance structure of covariates, and amount of zeros. We apply our method to the pancreas disorder length of the stay data collected from Western Australia.

The Purpose of this study is to classify the life styles of urban residents in apartments and to find out possible correlation with their preferences on interior ambience.The selected samples were 3,000 residents from Seoul, Pusan, Kwaungju and Cheonan, and 2,750 of them were analyzed.'The results can be summarized as follows.1.The life style patterns were classified into S types, namely organized type, decoration-oriented type, self expression type, practicality-oriented type and fashion-oriented type. 2. Interior image were classified into 4 types, namely characteristic image, contemporary image, classic image and rich image.3. The interior preference was correlated with the life style patterns, such as organizd type preferred to contemporary image, decoration-oriented type preferred to rich image, self expression type preferred to classic image and practicality-oriented type preferred to characteristic type.4. The patterns of life style and the interior preference differed significantly according to the size of apartment and the age of owner.

Purpose: Although serosal invasion is a critical predisposing factor for peritoneal dissemination in advanced gastric cancer, the accuracy of preoperative assessment using routine imaging studies is unsatisfactory. This study was conducted to identify high-risk group for serosal invasion using preoperative factors in patients with advanced gastric cancer. Materials and Methods: We retrospectively analyzed clinicopathological features of 3,529 advanced gastric cancer patients with Borrmann type I/II/III who underwent gastrectomy at Korea Cancer Center Hospital between 1991 and 2005. We stratified patients into low-(${\leq}40%$), intermediate-(40~70%), and high-risk (>70%) groups, according to the probability of serosal invasion. Results: Borrmann type, size, longitudinal and circumferential location, and histology of tumors were independent risk factors for serosal invasion. Most tumors of whole stomach location or encircling type had serosal invasion, so they belonged to high-risk group. Patients were subdivided into 12 subgroups in combination of Borrmann type, size, and histology. A subgroup with Borrmann type II, large size (${\geq}7$ cm), and undifferentiated histology and 2 subgroups with Borrmann type III, large size, and regardless of histology belonged to high-risk group and corresponded to 25% of eligible patients. Conclusions: This study have documented high-risk group for serosal invasion using preoperative predictors. And risk stratification for serosal invasion through the combination with imaging studies may collaboratively improve the accuracy of preoperative assessment, reduce the number of eligible patients for further staging laparoscopy, and optimize therapeutic strategy for each individual patient prior to surgery.
