Sj□gren's syndrome is a chronic inflammatory disease that predominantly affects salivary, lacrimal and other exocrine glands. We report a case of Sj□gren's syndrome combined with MALT (mucose associated lymphoid tissue) Iymphoma which occured in the parotid gland. A 57-year-old female with the complaint of painful swelling and iymph node enlargement was referred to our department. Sialograms of both parotid glands showed globular collections of contrast material uniformly distributed throughout the parotid gland. Salivary scintigraphy showed decreased uptake of the parotid gland. CT scan showed larger, slightly more dense parotid gland than normal and honeycomb glandular appearance. Also, It showed discrete, slightly more enhanced round mass in the left parotid gland. Histopathological finding showed replacement of salivary gland parenchyma with dense small lymphocytic infiltration having the feature of epimyoepithelial islands. Kappa light chain restriction of interglandular plasma cell could be seen. (Korean J Oral maxillofac Radiol 2000; 30: 144-148)

Internal derangement of the temporomandibular joint can be defined as an abnormal relationships of the meniscus relative to the mandibular condyle, articular fossa and eminence. This may cause variable mandibular dysfunctions and pain. For diagnosis, arthrography, computed tomography and magnetic resonance imaging are used. In this study, the authors reviewed 98 TMJs of 88 patients who were diagnosed as internal derangement through inferior joint space arthrography at the department of Oral & Maxillofacial Radiology, Dental Hospital, Dankook University through 1986 to 1992. 98 TMJs consisting of 30 disc displacement with reduction, 48 disc displacement without reduction and 20 perforation were studied about clinical and radiological findings. The results were as follows : 1. Internal derangement was found most frequently in the 2nd and 3rd decades and the average age of perforation was higher than that of disc displacement with reduction. The sexual predilection was 2 times higher in females. 2. The most frequent chief complaints were TMJ sound in displacement with reduction, pain and limitation of mouth opening in disc displacement without reduction and pain in perforation. The duration of the chief complaints was longer in disc displacement with reduction than in preforation and disc displcement without reduction. 3. Reciprocal click was the most frequently TMJ sound in disc displacement with reduction. History of joint sound in disc displacement without reduction and crepitus in perforation was the most frequent one. 4. The average maximum opening was 45.4mm in disc displacement with reduction, 31.4㎜ in disc displacement without reduction and 33.8mm in perforation. 5. In the centric occlusion, posterior condylar position was the most frequent in disc displacement with reduction, posterior and concentric condylar position was frequent in disc displcement without reduction, concentric and anterior condylar position in perforation. At 1 inch opening, the same position to articular eminence was most frequently found in disc displacement with reduction, posterior position in disc displacement without reduction, posterior and anterior position in perforation was frequently found. 6. Bony changes, especially sclerosis and flattening, was most frequently found in perforation.

한현정,전은경 울산대학교 2005 생활과학논문집 Vol.7 No.1

본 연구의 목적은 현대여성의 구두 착용에 따른 발 및 주변 부위의 문제점을 밝히는데 있다. 본 연구에서는 주된 구두 소비자 계층인 20대 여성들을 대상으로 소비자 설문조사를 통하여 구두 착용현황 및 그에 따른 발 장애를 살펴보고 구두 제작시 필요한 기초자료를 제공하고자 하였다. 본 연구의 결과를 살펴보면, 구두 착용여성의 대부분이 연령과 착용시간에 관계없이 많은 장애를 경험하였다. 그러므로 구두장애 요인 중 가장 많이 지적된 ‘구두골 치수’와 소재의 개선이 요구된다. 특히, 발둘레 치수에 대해서는 소비자와 판매자의 인지도가 약해 적절히 사용되지 못하고 있으므로 KS 규격에 대한 홍보가 필요하다. The purpose of this study was to identify the problems of women’s feet and it’s relative area caused by wearing shoes. This study was conducted through a survey with 384 young women consumers of 20s. Most respondents indicated that problems while wearing shoes. The reasons of the discomfort were ‘unfit of the size’ and ‘inappropriate materials.’ Most respondents were found to have the knowledge of their sizes but not of the letter sizes for the foot girth. Seventy six percent indicated that they of the respondents rarely know about the letter size. Most of the respondents (92.5%) indicated that they never checked the letter size when purchased shoes. This implicates that consumer education concerning the ‘KS G 3405 Lasts for shoes’ size system is necessary.

The purpose of this study is to examine the health status and health behavior of middle-aged Korean men and women. Even though there has been increased concern about extremely high mortality rate of Korean middle-aged men and mental health problems of middle aged women, there is a dearth of empirical studies which examine the health status and health behavior of middle-aged men and women in Korea. This study atternpts to frll these gaps. Data gathered from 1,667 men and women aged between 30-59 are analyzed to examine the level of physical health, mental health, perceived health and health behavior and to explore the gender and age group differences in these aspects. The results show that there exist gender difference and age group difference in health status: Women are less healthy than men and as age increased health status declined. Women at their 50s are least healthy and most unhappy suggesting age and gender interaction in health status. There exist a gender difference in health behavior: Mne have regular check-ups more frequently than women and exercise more. These results are discussed in terms of the gender difference in the experiences, social roles and life styles over the life course.

Fig(Ficus carica L.) which belongs to Moraceae family has been used as digestion promoter, cure for ulcerative inflammation and eruption in Korea. Figs have very short preservation period and can be kept only 1 week even in the refrigeration system. The possibility of wine-making from Korean figs was tested by analyzing the fermentation characteristics, proximate analysis and free sugar contents of wine made of slices with 20% sugar addition. Ethanol fermentation of the figs by Saccharomyces cerevisiae was done rapidly. The ethanol contents, pH, total acidity and sugar content were 12.1%, 3.91, 0.42% and 9.9 °Brix, respectively. The results from the sensory evaluation were as follows. The wine made from the sliced figs were better than that from fig juices in their sensory scores. The wine made with frozen figs was not different from that made with fresh ones. To improve the quality of wine, the addition of dried leaf powder in the concentration of 100 ppm were tried and found it was superior to the one made without leaf.

The colorectal corcinoma is one of the most common malignant tumor in Korea and its carcinogenic mechanism has not been elucidated exactly yet. So far, the most common carcinogenic mechanism has been known to be multiple genetic changes. But, the CpG island hypermethylation has been revealed to be one of the most important carcinogenic mechanism second to the genetic changes. The epigenetic changes characteristically imprint and transfer to the next generation without changes of nucleotide sequences. When the CpG island of promoter or 5'- exon 1 of a specific gene is methylated by DNA methyltrasferases (DNMTs), the gene expression is inhibited. Carcinogenic mechansisms by promoter methylation has been well known, but the progression of the cancer has not been elucidated yet. The molecular researches on the carcinogenic mechanisms largely depended on the tumor tissue containing various components of cell, due to difficulties in harvesting pure homogeneous tumor cells. Promoter methylatonof the cancer related genes as APc, hMLH2, p16, DAP-K and MGMT in 50 cases of sporadic colorectal carcinoma was studied. The pure normal colorectal epithelial cells, and cancer cells from superficial and deep invasive portion were harvested respectively by laser captured microdissection(LCM), and DNA was extracted from them. The promoter methylation was studied by methylation specific poymerase reaction (MSP) after bisulfite modification of the DNA and the expression of the genes by immunohistochemistry. The results suggests that promoter methylation of the cancer related genes are closely related with the colorectal carcinogenesis and it occurrs from early phase of carcinogenesis, progressing constantly to the late stage. And the promoter methylation of normal epithelial cells increased by age. The p15, known to be the genes related to hematologic malignancy, was closely related to the colorectal carcinoma as well.
