윤은숙,나영아,송태희 서울保健大學 1998 論文集 Vol.18 No.1
This study was investigated to the Korean restaurant menus from eight of the first class and five of the second class hotels in Seoul, and attempted to evaluate the restaurant evaluation and cooks job satisfaction with questionnaire surveys. The results were as follows : Korean restaurants of the first class hotel was on sale classified with a large table of food (so called kjo-ja-sang), Korean tabled hotel dinner(chong-sik), a Ia carte (il-pum yori), dessert, and wine with various prices and dishes. The first class hotel sold a lot of a large tables, second class hotel merchandised many Korean tabled hate dinner, both of them served from soup and stew of low price to high class dishes, served rice drink(sik-hei) and ginger tea with dried persimmons (su choung-kwa) with dessert, and served so-ju and bop-ju with Wine. Cooks whose sex were composed of 20% of female and 80% of male, ages were 52% of 20th, most of them graduated from high school or more. They had Korean, Western. Japanese or two or more of cooking license, had engaged in cooking for 5-10 years, worked 8 hours a day, made 1,000,000-1,500,000 won in a month. Most of them were satisfied with their job, possibilities, education training, and salary, whereas they dissatisfied with a cuisine environment such as room temperature, noise, illuminations. Therefore Korean restaurants need improve their working environment. Korean restaurants of the first class hotel had job description. standard cooking recipe, and job planing, hence we know that they were managed with scientific systems. We must attempt to survey menu design of food service system, western and Chinese restaurant as well.

It is known that the periodontal disease is caused by infection of inner oral bacteria as a suffering disease to human mankind for a long time. It can make the various clinical symptoms such as gingiva, bleeding, formation of periodontal pocket, loss of attached gingiva, collapse of alveolar bone and halitosis, and is known to the major contributor of loss of teeth. This study investigated the growth restraint effect of Camellia sinensis and Casia tora. As a result of study, the minimum restraint concentration of standard microbe on F. nucleatum for extracts from C. sinensis showed 2.5, 0.63 and 1.25 mg/ml, respectively and minimum restraint concentration of clinical separation microbe on F. nucleatum for extracts from C. sinensis showed 2.5 and 5.0 mg/ml. The minimum restraint concentration of standard microbe and clinical separation microbe, respectively. Meanwhile, the minimum restraint concentration of standard microbe and clinical separation microbe on F. nucleatum for extracts from C. tora showed 2.5 and 2.5-5.0 mg/ml, respectively. The minimum restraint concentration of standard microbe and clinical separation microbe for P. intermedia, P. nigrescens, P. gingivalis, and P. endodontalis showed above 5.0 mg/ml for standard microbe and above 5.0 mg/ml for clinical separation microbe, respectively. As a result of investigating the cell toxicity for each extracts, extracts from C. sinensis does not showed the toxicity for the cell below the concentration of 2.5 mg/ml, but it showed toxicity for the cell above concentration of 2.5 mg/ml and it decreased the existence ratio for the cell. Meanwhile, in the case of C. tora, it increased the multiplication ratio below the concentration of 1.25 mg/ml compared to the subject group and it decreased gradually the multiplication ratio that the growth ratio for the cell is increased better than subject group. As a result of this study, extracts from C. sinensis was more effect on the growth restraint effect against periodontopathogens than extracts from C. tora and is proven that it is possible for use as a oral mouthrinsing liquids in the near future. On the basis of results of this study, it is judged that the study for reaction mechanism and discrete clinical test for implementation should be needed.

金泰浩,尹志淑 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.2
The swelling properties of P(VA-co-MMA) membrane and the permeability of theophylline through that membrane were studied. P(VA-co-MMA) polymers were prepared by copolymerization of vinyl acetate and methyl methacrylate at mole fraction of NM, f_1 = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 1.0 by γ- irradiation, followed by methanolysis of the produced copolymer. The number average molecular weight M￣_n and the weight average molecular weight M￣_w were calculated as 17,800 - 19,000 and 47,700 - 57,400, respectively. The membranes were casted as the crasslinking ratio of X = 0.01 and 0.005, with glutaraldehyde in 50 vol% ethanol-water. The equlibrium water content and the tensile strength of the membranes were determined. The microstructures of the membranes were studied by SEM and DSC. The theophylline partition coefficients and diffusion coefficients were in the range of 0.994∼1.342, 3.53×10 exp(-6)∼5.46 x 10 exp(-6)㎠/sec, respectively.

Purpose : This preliminary study was done to identify sex related characteristics and sex knowledge of high school students. Methods : 622 high school students participated in the survey living in Gangreung city area. The data collection was done from May 1st to October 31st, 2000 using the self administered questionnaires. Results : The teachers and the peer students had a critical position in high school sex education. Reproductive physiology such as relations with the opposite sex, AIDS, STI, and contraceptions should be intensified in further sex education for high school students. There were sex differences in contraception and permission with sex relationship. And the false belief regarding sex assaults and knowledge deficit in AIDS were discovered. Conclusion : Sex education program development and application are necessary based on the educational needs and attitude evaluation for the sexual health improvement of high school students. In further study, developing the reliable measurement tool and various educational methodologies will be studied which are enough for the include the sex education concepts.

서울시 대기오염과 일별 사망의 상관성에 관한 시계열적 연구 (1998~2001년)
조용성,이종태,김윤신,홍승철,김호,하은희,박혜숙,이보은 한국대기환경학회 2003 한국대기환경학회지 Vol.19 No.6
This study was performed to examine the relationship between air pollution exposure and mortality in Seoul for the years of 1998~2001I. Daily counts of death were analyzed by general additive Poisson model, with adjustment for effects of seasonal trend, air temperature, humidity, and day of the week as confounders in a nonparametric approach. Daily death counts were associated with CO (current day), 0₃(current day), PM_(10) (current day), NO₂, (1 day before), SO₂, (1 day before). Increase of 41.711㎍/㎥ (interquartile range) in PM_(10) was associated with 1.3% (95% CI = 0.7~1.9%) increase in the daily number of death. 0₃concentrations resulted in an increased risk of 1.3% for 23.86 ppb in all-aged mortality [RR = 1.013 (1.004-1.023)]. This effect was greater in children (less than 15 aged) and elderly (more than 65 aged). After ozone level exceeds 25 ppb, the dose-response relationship between mortality and ozone was almost linear. We concluded that Seoul had 1~5% increase in mortality in association with IQR (interquartile range) in air pollutants. Daily variations in air pollution within the range currently occurring in Seoul might have an adverse effect on daily mortality. These findings also support the hypothesis that air pollution, at levels below the current ambient air quality standards of Korea, is harmful to sensitive subjects, such as children or elderly.

세포질내 정자주입법(ICSI)에 있어서 정자흡입 및 난자내 주입방법에 관한 연구
이택후,김항진,송건호,김대근,전상식,박윤규,서태광,전병균,류은경,이은숙,문진수,김광철 경북대학교 의학연구소 2000 경북대학교병원의학연구소논문집 Vol.4 No.1
Study on Method of Sperm Aspiration and Injection into an Oocyte in Intracytoplasmic Sperm Injection(ICSI) Immobilization of spermatozoa prior to intracytoplasmic sperm iniection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first. Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization cleavage, percentage of grade I embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes ware inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30μl drop of mHTF supplemented with 10% heat-inactivated follicular fluid(FF) at 37℃. On day 2. embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF + 10% FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to earth treatment and ICSI was performed(88 head-first, tail-first). The rates of normal fertilization were 81.8% and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9% and 68.8%, 93.1% and 74.1% for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4%(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.

Yoon, Tae-Sook,Cheon, Myeoung-Sook,Lee, Do-Yeon,Moon, Byeong-Cheol,Lee, Hye-Won,Choo, Byung-Kil,Kim, Ho-Kyoung The Korean Society for Applied Biological Chemistr 2007 Journal of Applied Biological Chemistry (J. Appl. Vol.50 No.4
Root extracts of Angelica gigas and A. acutiloba have been used traditionally for the treatment of gynecological diseases, as well as anemia, blood stasis, and inflammatory pain, as blood tonics in Oriental medicine. In the present study, we investigated the effects of A. gigas and A. acutiloba on inflammatory mediators in mouse macrophages and compared their activities. Many studies suggest that prostaglandin $E_2$ ($PGE_2$) biosynthesis and nitric oxide (NO) production play important roles in the processes of both inflammation and carcinogenesis. Ethanolic extracts from the roots of both species exhibited significant inhibitory effects on $PGE_2$ generation in lipopolysaccharide-stimulated RAW 264.7 cells. In particular, the extract from A. gigas was more effective than that from A. acutiloba. Although neither inhibited NO generation, the extract from A. acutiloba stimulated NO generation. Our results suggest that the roots of A. gigas might possess more anti-inflammatory and/or cancer chemopreventative activity than that of A. acutiloba due to the suppression of cyclooxygenase-2 (COX2)-mediated $PGE_2$ production. In addition, A. acutiloba might exert anti-tumor activity through an increase in macrophage-produced NO.
