南命錫,李奎恒,金顯東 大韓神經精神醫學會 1966 신경정신의학 Vol.5 No.1

The anticonvulsive effect of Diamox was observed on 35 epileptic patients consisted of 18 old ones and 17 fresh ones, from May, 1965 to Sep, 1965, at the Neuropsychiatric Department of Seoul National University Hospital and The 3rd Army Hospital. Among 35 epileptics 9 cases were symptomatic, others idiopathic and in the age of the initial onset 20 cases were from 10 to 19 years old of patient's age 9 cases from 20 to 29, 3 cases from 30 to 39, 3 case over 40. 29 cases of them were grandmal and other mixed in clinical type. The doses of medication was 1-2gm/day without any other anticonvulsants, during two months over. We devided the effectiveness into four groups, Good (80-100% improvement), Fair (50-80% improvement), Poor (0-50% improvement), Wore (increased in frequency). RESULTS: 1) We could observe the good response in 57.1% of patients. The more fresh revealed the better result. (TableⅠ) 2) No distinction between the idiopathic and the symptomatic could be found in response. (TableⅢ) 3) The case of the more frequent attack revealed the better response. (TableⅣ) 4) The side effects could be found in 88.3% of patients. Among them, paresthesia was most predominant symptom. (Table Ⅴ) No severe side effect was observed in all cases. We could control them with decrease of dosage or without any mangement, 5) Some problems remain: a) The clinical type and the degree of response. b) The evaluation of the child epilepsy. c) EEG pattern and degree of response. d) The biochemical study on the mechanism of action. We should like to perform above problems at another chance.

투명 경영제도와 재무적 성과

남명수,신현관 한국기업윤리학회 2003 企業倫理硏究 Vol.6 No.-

The corporate governance of our firms has the agency problem between major stockholders/management and majority stockholders. In order to solve this conflict, the government should take such special measures as the composition of out-sider-dominated boards or the adoption of cumulative voting and class-action suit provisions as the minimum devices to maintain the transparent and accountable management. But, before amendment or adoption of such provisions, the market information collected through the evidences of the previous studies should be fully considered. Outsider-dominated boards are likely to appoint outside CEO candidates when the firm faces a dramatic change in the business policies. The evidence from previous studies of stock price reactions to board decisions indicates that the market tends to view decisions by outsider-dominated boards more favorably than similar decisions by insider-dominated boards. The results of previous studies support that cumulative voting rights can increase firm value. In a derivative suit, possible manager-shareholder conflicts have increased the debate over the role of indemnification and directors' and officers' (D&O) liability insurance. The effect of D&O insurance on stock price is positive, but the broadening of indemnification has no significant effect on stock price. In a class action suit, if the rumor that shareholder will raise a lawsuit against a corporation is spread out in the market, the stock price will be dropped by about 30%. Because a class action suit adversely affects stock price, it should t allowed to shareholders in the direction to minimize its negative effects.

The purpose of this research is to verify the relationship between the changes of the operating cycle and the changes of the stock price in the firm. If the reduction of the operating cycle means a positive result of successful business reengineering of an enterprise whereas the increase in the operating cycle has an immense impact on stagnant sales and inefficient inventory management, a negative correlation is expected to exist between the operating cycle and the stock price. Following is a summary of this research ; First, the changes in operating cycle or the ratio of cash cycle and the stock price has a negative correlation. This finding is evident within industries of electronics, transportation equipment and machineries, but not so obvious in other industries. Secondly, the following findings are established for the operating cycle, cash generation capability, and the stock price ; ·As the capability of cash generation increases, the stock price increases. ·As the operation cycle extends, the stock price and the capability of cash generation decreases. Third, a negative correlation is found in the relationship among the raw material, work-in-progress, finished goods and account receivable collection and is maintained between the stock price and each respective factor. And finally, when the operating cycle is extended a negative correlation is found between the stock price and the operating cycle whereas when it is shortened such negative correlation is not found. This indicates only a negative impact on the operating cycle is relevant to the stock price.

Numerical study was investigated to the transient natural convection in a square cavity. The cavity is filled with the pure substance of a low Prandtl number and the vertical walls are constantly maintained different temperature, while the horizontal boundaries are adiabatic. A control volume approach with a central difference scheme is used to formulate the finite difference equations. The results were presented transient Nusselt number, stream function and temperature distribution. It was found that the flow pattern and heat transfer exhibit time-periodic oscillation at various conditions. The average Nusselt number, the amplitude and the frequency of oscillation increases as the Rayleigh number is increased. The increment of Prandtl number makes that the amplitude and the frequency of oscillation reduced, and average Nusselt number increased.

Background: Most cases of Graves' disease have been treated by antithyroid drugs in Korea. The major drawbacks of antithyroid drugs are the relative high rate of relapse and the inconvinience of long term therapy. Measurement of TBII and TRH stimulation test have been considered as the most reliable tests predicting relapse, but the predictive power is not high enough to use in clinical situation. This study was performed to find good prognostic indicators in Graves' disease patients after the discontinuation of antithyroid drug therapy. Subjects and methods : We restrospectively evaluated 96 patients with Graves' disease who showed normal TRH test at the end of antithyroid drug therapy and were followed for more than one year. Serum T3, T4, T3/T4 ratio, TBII, Anti-TPO Ab and TGAb levels were measured at the time of diagnosis and at the end of therapy. Two to three months after withdrawal of antithyroid medication, serum TSH and free T3 responses to TRH were examined. These parameters were compared between the relapse group and the remission group. Results : Among the 96 patients, 22 patients(22.9%) relapsed(Group Ⅱ) and 74 patients(77.1%) remained in remmision(Group Ⅰ). No significant difference was observed between the relapse and the remission group in clinical parameters, serum T3, T4, TSH, T3/T4 ratio, TBⅡ and Anti-TPO Ab determined before and after treatment. Serum TSH and free T3 levels measured after TRH stimulation were also similar in both groups. Serum TGAb levels determined at the end of treatment were significantly higher in the remission group(p<0.05). Relapse following the discontinuation of therapy occured within 24 months in 72.7% of the relapsed cases. After 24 months, relapse rate was reduced significantly. Conclusion : These results suggest that high serum TGAb levels could be a favorable prognostic indicator for the long term remission of Graves' disease treated with antithyroid drugs, and may suggest that Hashimoto's thyroiditis is combined with Graves' disease in those patients.

盧明來,南光鉉 순천향대학교 1981 논문집 Vol.4 No.1

Study on the Korean Standard MMPI was performed on both the 1374 stealing boys who were institutionalized to the Seoul Juvenile Detention and Classification Center and the 317 normal high school boys sellected as control groups. These 1374 stealing delinquent boys were classified into 4 groups according to their nature of criminal acts, namely, 1) one delinquent boy's simple stealing group (600 subjects). 2) unlawful night entry stealing boy group (128 subjects). 3) more than two delinquent boy's specific stealing group (545 subjects) 4) habitual stealing group, more than 4 times stealing episode (101 subjects) . Emphasis was based on between the characteristics and differences of these 4 stealing del-inquent boy groups and the normal control groups. Especially the delinquent scale of simple stealing group and more than two boy's specific stealing group were extracted by the method of item analysis. The results were as follows: 1) Statistically significant higher score was obtained in nearly all clinical and validity scales except the Mf scale in the stealing groups compared with the normal control group 2) 19.56% of the normal control group. 36.83% of the simple stealing group, 27.34% of the unlawful night entry stealing group, 35.60% of the specific steeling group, 36.65% of the habitual stealing group revealed neurotic or psychotic traits. 3) The level of anxious state was higher in the stealing groups compared with normal group and, the highest anxious state was the unlawful night entry stealing group. ' 4) The internalization ratio was also higher in the stealing groups compared with the normal control group. This trait reveled that both group act out their anxiety and tension state to the outside, but the degree of acting out was lower in simple stealing group . 5) On item analysis, 74 delinqent scales in simple stealing group and 63 delinquent scales in specific stealing group were obtained.

This research is results of experimental and numerical works on characteristic of strength increase and bearing capacity in dredged and reclaimed soil due to desiccation shrinkage. For a soil sampled from southern coastal area in Korea, basic soil property tests and standard consolidation test with falling head permeability tests were carried out to obtain consolidational characteristics of soil. Double cone penetration test. laboratory vane test and unconfined compression test were also performed to investigate the change of shear strength with degree of desiccation. Model tests were performed in 1G environment and 30G level artificially accelerated condition by using the centrifuge model test facilities to investigate the bearing capacity of desiccated ground. Test results were analyzed by using the bearing capacity of desiccated ground. Test results were analyzed by using the theoretical and load-settlement characteristics method proposed by Meyehof & Hanna(1978). On the other hands, the numerical technique, using the finite strain consolidation theory considering the effect of desiccation was used to estimate the appropriate time of using heavy construction equipments in field with respect to strength increase due to desiccation.

권대현,김신유,남정순,구명숙,이봉서,권대근,김종배 大韓顎顔面成形再建外科學會 2001 Maxillofacial Plastic Reconstructive Surgery Vol.23 No.6

The cemento-ossifying fibroma is a benign fibro-osseous tumor that may behave in an aggressive pattern. Although found predominantly in the mandible, most of these unusual tumors may arise in the maxilla and paranasal sinuses. Especially these lesion in the maxilla and sinuses behave more aggressively and are more prone to recur compared to mandibular counterparts. Therefore, more radical approach may be recommended than expectant observation or curettage in the initial management of this neoplasm. This is a case report of cemento-ossifying fibroma extended to maxillary sinus and naso-ethmoidal area treated by wide surgical excision after repeated conservative treatments.
