This study was conducted to suggest appropriate methods for management of urban forest after investigating the present condition and problems of urban forests by analyzing vegetation and soil properties in urban forests in the Daejeon. On the basis of our research, Pinus rigida dominate Gyejoksan and Bomunsan. Pinus densiflora dominate Wolpyeong park and Quercus acutissima dominate Namsun park. On the basis of our result of analysis of soil chemical properties, all investigated areas have low pHs, available phosphates and exchangeable cations. They indicate that the soil of those areas have been acidifying progressively. Soil hardness measurements were conducted to know the conditions of trampled soils and the results of them show that soil hardness in Namsun park was higher than the others. This indicates that human interference affect the health of the urban forest.

To examine the impact of amenorrhea on bone mineral density in women of reproductive age, 22 amenorrheic women aged 16-40 were studied Bone mineral density in the lumbar spine(L1-L4) as measured by dual energy X ray absorptiometry. The amenorrheic group showed a mean reduction in bone mineral density of 155 as compared with controls. Bone loss was related to the duration of amenorrhea and the severity of estrogen deficiency rather than to the underlying diagnosis. Patients with a history of fracture had significantly lower bone density than those without a history of fracture. In conclusion, amenorrhea in young women should be investigated and treated to prevent bone mineral loss. Menopausal women with a past history of amenorrhea should be considered to be at high risk of osteoporois.

Thirty-eight healthy, perimenopausal women (aged 42-54 years) were allocated to 6 months of over of treatment with a cyclic combination of 2 mg estradiol valerate and 1 mg cyproterone acetate. 1. Satisfactory response to hormonal treatment was noticed in 32 patients (84.2%), but unsatisfactory response was noticed in 6 patients (15.8%). 2. Unsatisfactory response was especially noticed in group of patients who were in regular menstruation but complaines of menoparsal wymtoms. Accordingly, if unsatisfactory response was noticed, other couses of menopausal symptoms were evaluated, especailly ofr psychologic factor or stress factor. 3. After hormonal treatment body weight and blood pressure were not singificantly chanded. 4. After hormonal treatment GOT, GPT, alkaline phospatase, BUN, FBS, creatinine, triglycerid, HDL-cholesterol and total cholesterol were not significantly changed. 5. Side effects of durg were negligible and patiens were well tolerated the drug and compliance were good. On conclusion, it has suggested that a combination of estradiol valerate and cyproterone acetate was safe and effective for the treatment of menopausal symptoms without side-effects. However effects on bone density with this durg should be evaluated.

119 amenorrheic patients were diagnosed in the department of Obstetrics and Gynecology of Chungnam National University Hospital and Hanyang University Hospital during the period of 57 months from November, 1979 to July, 1984. The retrospective study was undertaken to determine whether or not the division of patients with amenorrhea into specific categories based on physical findings and specific laboratory tests would be valid and useful for the differential diagnosis of amenorrhea. The results obtained were as follows : 1. Of 119 amenorrheic patients 38 patients (31.9%) were primary type and 81 patients (68.1%) were secondary type. 2. Of 38 primary amenorrheic patients the most common cause of the amenorrhea was hypogonadotrophic hypogonadism (9 cases). The cause of the remainder was Turner syndrome (5 cases), testicular feminization (5 cases), gonadal dysgenesis (3 cases), hypothalamic dysfunction (3 cases), hypothalamo-pituitary failure (3 cases), Rokitansky syndrome (2 cases), pituitary adenoma (2 cases;, Stein-Leventhal syndrome (2 cases), ovarian failure (2 cases), CO poisoning (1 case) and anorexia nervosa (1 case). 3. Of 81 secondary amenorrheic patients the most common cause of amenorrhea was hypothalamic dysfunction (42 cases). The cause of the remainder was functional hyperprolactinemia (11 cases), premature menopause (9 cases), Stein-Leventhal syndrome (6 cases), hypothalamopituitary failure (5 cases), pituitary adenoma (4 cases), hypothyroidism (1 case), empty sella syndrome (1 case), Sheehan's syndrome (1 case) and adrenal masculinizing tumor (1 case). 4. 119 amenorrheic patients were classified into 3 group : 1) breast development absent and uterus present (17 cases), 2) breast development present and uterus absent (7 cases), and 3) both breast development and uterus present (95 cases). 5. Patients in category 1 were diagnosed as having hypogonadotrophic hypogonadism or gonadal dysgenesis. Patients in category 2 were diagncsed as having Rokitansky syndrome or testicular feminization. Patients in category 3 were diagnosed as having ovarian failure, Stein-Leventhal syndrome, hyperprolactinemia, hypothalamc dysfunction, or hypothalamo-pituitary failure. 6. Patients in category 1 could be differentiated by measurement of serum FSH level. Patients in category 2 could be differentiated by chromosome study. Patients in category 3 could be differentiated by following method. By measurement of serum FSH levl ovarian failure was differentiated. Of the remaining patients, patients with Stein-Leventhal syndrome were identified by measurement of serum LH. The next step of measurement of serum prolactin could identify hyperprolactinemia. The remaining patients were divided into hypothalamic dysfunction or hypothalamo-pituitary failure by progesterone withdrawal test. This study demonstrated that it is possible to classify patients with primary or secondary amenorrhea into 3 useful diagnostic categories based on physical examination and minimal laboratory test.

김형철,강길호,채만규,김성용,백무준,이문수,박상흠,이문호,김창호,송옥평,조무식,박희주 순천향의학연구소;Soonchunhyang Medical Research Institute 2000 Journal of Soonchunhyang Medical Science Vol.6 No.1

Purpose : The Mirizzi syndrome is relatively rare and preoperative diagnosis of this disease is difficult. In 1978, Morelli suggested the subclassification of the Mirizzi syndrome into acute or chronic form. We experienced 5 cases of acute form. We analysed clinical features, preoperative radiologic findings and operative findings of 18 cases including acute forms which were diagnosed as Mirizzi syndrome and should suggest the modified classification of Mirizzi syndrome for choice of appropriate treatment. Method : From January 1995 to December 1998, 18 cases, of which 8 cases were diagnosed at Soonchunhyang University Chunan Hospital, and 10 cases were reported in the Korean Journal were retrospectively analysed with regard to clinical features, preoperative radiologic findings and operative findings. According to the clinical features, whole cases were divided into type Ⅰ(acute form) and type Ⅱ(chronic form) and then each type of cases were subclassified according to preoperative radiologic findings and operative findings. Results : Of 18 cases there were 5 cases in type Ⅰ(27.8%), 13 cases in type Ⅱ(72.2%). Type Ⅱb was most common. Type Ⅰa cases were treated only with cholecystectomy. We applied cholecystectomy, T-tube choledochostomy and patch technique in type Ⅰb and thpe Ⅰc cases. Cholectystectomies including removal of gallstones and internal drainage procedures were done in type Ⅱ chronic forms. Conclusion : The acute form(Type Ⅰ) of Mirizzi syndrome was suggested by Morelli might be subclassified into typeⅠa,Ⅰb and Ⅰc following the presence of the necrotic defect in common hepatic duct. Through the modified classification of Mirizzi syndrome based on clinical feature, preoperative radiologic findings and operative findings, we can choice appropriate treatment.

A survey of seawater pollution was carried out monthly during October 1979 through May 1980 for three major harbors in Jeju island ; Jeju, Seogwipo and Seogsanpo. Eight different sites were selected for each harbor to determine a chemical and microbiological pollution level together with a pigment content. Among three harbors, Jeju was most polluted chemically and microbiologically with significantly high level of pollution at the inner harbor which were well above the maximum permitted level. The inner harbor of Seogwipo also was in excess of permitted level under the influence of Cheonjicheon, but the other sites were rather clean. Seongsanpo is not polluted at the present time. It was shown that the pigment contents in seawater were higly variable from month to month. The highest pigment content in Jeju with the similar low values in Seogwipo and Seongsanpo were obtained oqter port. This indicates that the sites with inflowing fresh water or sewage were and carotenoid. throughout the investigating period. The differences in the pigment contents among the sampling sites showed that the inner harbor was much higher than outer prot. This indicates that the sites with inflowing fresh water or sewage were generally high in pigment content. In pigment sorts, there always appeared higher amount of chlorophyll c than chlorophyll a,b and carotenoid.

본 연구에 사용한 가압기포유동층장치는 가압기체공급부분, 가압유동층, 미분체포집부분등으로 이루어져 있다. 가압기체공급은 30HP compressor를 이용하였고, 가압기포유동층은 스텐레스 철로 만들었는데 직경은 0.1m 높이는 3.5m로 하였다. 가압유동층에 사용한 유동입자는 188∼875㎛의 4종류로 국내산 무연탄을 사용하였고, 적용한 실험 변수는 유동입자, 층내부의 압력(100∼500kPa), 과잉기체유속(U-Umf; 0.05∼0.25m/s) 등으로 결정하였다. 상온 상태에서 가압유동층에서 국부적인 압력 변동에 관한 통계적 해석으로 strange attractor 표준편차 및 Fractal 해석을 적용하였다. 가압유동촌에서 strange attractor는 기체유속이 증가하면 커지고 압력이 증가하면 감소하였다. 또한, strange attractor의 궤적 및 Pox diagram의 경향성으로부터 기체 유속보다는 압력의 영향력이 더 크게 작용함을 알 수 있었다. 표준편차 및 Fractal 차원은 과잉기체유속이 증가하면 증가하고, 압력이 증가하면 감소하였다. Strange attractor와 표준편차는 상관성이 좋고, 표준편차와 Fractal 차원과는 상관성이 잘 나타내고 있음을 확인할 수 있었다. Equipment used in this study were composed of pressurized air generating part, fluidization column. and fine particle collecting part. The compressed air used was sullied by 30 HP compressor into the fluidization column which was an 10cm diameter and 3.5m height. The pressure (100-500 kPa) was measured with sensor and regulated by means of globe valves. The gas phase, pressurized air, was fed to the column(excess gas velocity, U-Umf=0.05-0.25m/s) through distributor. The solid phase Particle used was coal particles(188-875 ㎛). The obtained data can be analyzed by strange attractor, standard deviation, and Fractal dimension obtained from the stochastic analysis of local pressure fluctuations at room temperature in the pressurized bubbling fluidized bed. The strange attractor increases with increasing gas velocity and decreases with increasing pressure. A tendency defined from the trace of strange attractor and the Pox diagram represented that pressure was more important than gas velocity in these experimental conditions. Both standard deviation and Fractal dimension increase with increasing gas velocity but decrease with increasing pressure. Results obtained from stochastic analysis of pressure fluctuation source show good correlation between strange attractor and standard deviation, and also between standard deviation and Fractal dimension.

李允中,曺正吉,朴元敎,李康春 成均館大學校 科學技術硏究所 1988 論文集 Vol.39 No.1

A simple and highly sensitive method for the determination of unsaturated fatty acids (C_16:1, C_20:4, C_20:5) is described. I-Bromoacetylpyrene was used as the pre-column fluorescent labelling reagent for HPLC. Fatty acids were derivatized quantitatively into fluorescent compounds by treating with 1-bromoacetylpyrene in the presence of 18-crown- 6 in acetonitrile. The optimum conditions for the derivatization such as, concentrations of KOH, 18-crown-6, and 1-bromoacetylpyrene, reaction temperature and reaction time, were investigated. The derivatives were separated on a reversed phase column (LiChrosorb RP-8, 5 ㎛) using the tertiary mixture of acetonitrile, methanol, and water as the mobile phase. The effluent was monitored by fluorometer (excitation wavelength; 366 nm, emission wavelength; 454 nm). Linearities of calibration curve were obtained between 5.0 p mol and 40.0 p mol. The detection limit of fatty acids was 1 p mol in a 20μl of injection volume.
