This study purposed for analysis of the factors affecting Korean Medical License Examination(KMLE) grades in Kwandong University Medical College students. Twenty-seven graduate students were evaluated with stress perception scales and socio-economic state evaluation scales. The results were as follows: 1.The students feel high stress in 'Recent pressure in past one week', 'pressure in interpersonal relationships' and 'economic pressure'. 2.The scores in 'Recent pressure in past one week', 'pressure in interpersonal relationships' and 'occupational pressure' were in significant correlations with the KMLE scores. These results suggest that the Kwandong Medical students feel stress in chiefly in the interpersonal relationships and these factors affecting KMLE scores.

Objectives : Regarding the relationship between the laterality of seizure focus and depression in temporal lobe epilepsy (TLE), previous studies reported inconsistent results. The role of frontal function as moderating variable between laterality and depres-sion had been proposed. We attempted to replicate functional involvement of frontal lobe (FIFL) and, as an effort to extend previous findings, to test the functional involvement of parietal lobe (FIPL) to prove the hypothesis derived from Heller's Valen-cearousal theory of emotion. Methods : In study 1, Patients with TLE (right 19, left 17) performed MMPI-D as a depression measure, Wisconsin Card Sorting Test (WCST) as a frontal function measure, and block design (BD) as a parietal function measure in the course of pre-operation assessment. Multiple regression model of depression which includes the interaction terms both between laterality and WCST and between laterality and BD were tested, In study 2, Patients underwent anterior temporal lobectomy (ATL ; right 20, left 25) were assessed and analyzed in the same way as study 1. Results : In study 1, contrary to the FIFL and FIPL prediction, interaction of laterality with WCST or BD were not significant. In study 2, the interaction with frontal function was significant, Consistent with FLFL prediction, depression came to be evident when seizure focus was lateralized to the left side and simultaneously frontal function declined. But the interaction with BD remained insignificant, which suggests the invalidity of FIPL hypothesis. Conclusion : We replicated the FIFL hypothesis in the depression of ATL patients. The relation of depression with frontal function was more evident in post rather than pre operation sample. This pattern may be due to the inter-hemispheric interference of frontal functions in pre-operation sample and to the release-of-function phenomenon in post-operation sample. On the other hand, we did not succeed in confirming the role of pahetal function in depression. Intactness of the parietal function in TLE was considered as the main cause of the negative finding.

제창웅,진승준,정동석,임성택,이용연,박노진 대한금속재료학회 2004 대한금속·재료학회지 Vol.42 No.10

The texture and mechanical properties during fabrication processes - extrusion, cold rolling and aging treatment - of plate in the 7050 Al alloys without/with 0.1%Sc were investigated. In both the cross section(CS) and longitudinal section(LS) of the specimen without Sc, after cold rolling, texture of R-fiber was predominant. In the Sc added alloy after cold rolling, {112}<111>(Cu)+weak (123)<634>(S) texture components developed in the CS of the specimen while strong (3-fiber+(110)<001>(Goss) components developed in the LS of the specimen. After solution treatment and aging treatment, the alloy (CS and LS) without Sc had random texture, but by the alloys with the 0.1%Sc, the components of the rolling texture are not changed. After the aging treatment, hardness and tensile strength of the alloy with 0.1%Sc increased about 15% and 17%, respectively, than those without Sc. Tensile strength of the Sc added specimen was the highest along the rolling direction where the <111> texture was strongly developed. On the other hand, in the specimen without Sc, the mechanical properties were not dependent on the direction of the sample. (Received May 3, 2004)

金雄成,田載植 충남대학교 1985 忠南科學硏究誌 Vol.12 No.1

Mean energy required to produce an ion pair, W-value, is one of the fundermental quantities in radiation physics and dosimetry. As a preliminary stage of W-value study a series of experimental measurement of Alpha particle ranges in several different gases was carried out. The gases used are air, N_2, CO_2 and CH_4 that are known as tisse equivalent, and the sources of alpha-particle used are ^241Am(E_α:5.48 MeV) and ^230Th(E_α:4.68 MeV), respectively. For the measurement of the range of alpha-particle in the gases, a chamber was specially designed and constructed in order to control the pressure of the gases from 200torr to 1500torr as well as the source-to-detector distance from 2 to 40 ㎝. The detector embedded in the chamber was a Si surface barrier detector, and the output signals were fed into a multichannel pulse height analyzer. The results obtained were assessed in comparison with theoretical calculation of the ranges in various condition and, very good agreements were drawn, except for the case of CH_4 gas which showed a slight descrepancy between experimental and theoretical values of the ranges. Throughout whole part of the study, a possibility of experimental measurement of dissipation energy of a charged particle in a gas at given pressure is shown on practical basis.

Studies on physiological cause of obesity, and research on literature about nutrition and excercise prescription programs for the problem solving have led to the following results. 1. The size and number of fat cells increase sharply during childhood, become stable passing the adolescent period and re-increase at the time of adults. In this sense, earlier diagnosis and treatment of overweight children could prevent adult fatness. 2. A conversional mechanism involving glycerol and fat acids, which is catalyzed by increasingly activated fat dissolution generates fatness and relates to the resistance of insulin and development of diabetes. 3. High calory and fat diets and their physical shapes, flavors and tastes could affect the generation of fatness. 4. DIT as lower relative to a given calory and a defective heat generation of BAT could lead to cumulative body fats. 5. Roles of appetite relate to maintaining balance DIT and consumption calory, staying a weight at a certain level. The malfunction of the lower part of thalami, however, results in hyperphagia and ultimately fatness. 6. The biological adjustment of energy consumption for weight maintenance in spite of energy intake is referred to as set-point. This is possible through diet and exercise. VLCD suppresses appetite too forcefully, and it is common to fail to decrease weight and return to initial levels. Instead, WC is applied which repeats weight decrease, restoration, weight decrease and restoration in order. The more the approach repeats, the more difficult reduction in weight is. 7. Therapies for fatness include those of diet, exercise, behavior and drugs. It is more effective to use diet and exercise therapies together. In this regard, solving the fatness problem depends on nutrition and exercise programs as very suitable for the overweighted people. 8. For a diet therapy, calory to be taken is limited 15 to 20 kcal per overweight, and combination percentages of protein, carbohydrate and fat should be respectively 20,45 and 35 percent while for an exercise therapy, aerobic types of exercise such as walking, jogging, cycling and swimming should be used in such way that they are performed 3 to 6 times a week, 15 to 20 minutes or over each time at the intensity of 60 to 80% of the highest heart rate. 9. Since such exercise programs tend not to be practiced continuously, it is required for the programs to be initially prepared with consideration of motivations and interests on the part of the programs' clients.

The microstructure and mechanical properties of directional solidified Ti-47Al-3Nb, Ti-47Al-3Nb-0.2Si- 0.1C, Ti-47Al-3Nb-0.3Si-0.2C alloys were investigated. It was found that the lamellar thickness of Si and C doped alloys was fine and uniform, and little or no precipitates were found. Room temperature yield stress increased rapidly with increasing Si and C contents due to fine lamellar distribution and solid solution hardening. However, fracture toughness of type I specimens of the alloys decreased slightly with increasing Si and C contents. It was considered that α2 volume fraction decreased with increasing Si and C contents so that the delamination-type separation was decreased which contributes the high resistance of crack propagation for type Ⅰ specimens. Furthermore, fracture toughness of Ti-47Al-3Nb-0.2Si-0.1C alloy specimens with type Ⅰ orientation, polycrystalline form, and with type Ⅲ orientation increased in order of type Ⅲ, polycrystal and type Ⅰ. These results are discussed and the ability to obtain a respectable combination of strength and toughness through Si and C addition to a TiAl-Nb alloy produced by directional solidification is demonstrated.

This study was conducted to examine the excretion rate of dimethylformamide(DMF) from the workers exposed to DMF. The study was done at two synthetic leather factories located in Kyeonggi-do from the period of May 2 to 30, 1996. N-methyl-formamide (NMF) concentrations in urine were measured and compared by the three exposure level of DMF in air. The mean concentration of the Low (dry and winder part), Moderate (rinsing part) and High (mixing and coating part) exposure group were 3.99±3.54, 10.19±5.69 and 32.10±7.87㎎/㎥ during workshift of 8 hours, respectively. The mean concentration of urinary N-methylformamide (NMF) were 2.13±2.58, 11.16±4.98 and 26.24±7.35㎎/g creatinine, respectively. The concentration of NMF in urine could reach to maximum in 3 hours and was reduced nearly to zero in about 18 hours after exposure to DMF.

88 workers exposed to cadmium were examined at the 12 factories using or producing cadmium in order to know the present state of cadmium exposure and renal dysfunction in 1992. Cadmium in blood and in urine were measured and compared by the 3 exposure level of cadmium in air. Cadmium in blood of low, moderate and high exposure group were 2.5, 3.8 and 7.6 ㎍/L, respectively. Cadmium in urine were 1.8(1.3), 3.8(2.6) and 7.9 ㎍/L(6.1 ㎍/g creatinine), respectively. However, there was no relationship between urinary cadmium and β₂-microglobulin. Cumulative exposure estimate(CEE) was calculated by multiplying the mean ambient cadmium level of the factory and working duration. CEE has a high correlation with cadmium in blood and urine, but no relation to β₂-microglobulin. Because working durations were relatively shorter than European workers', the highest CEE was just 300 ㎍·year/m³, which was not enough to induce renal tubular dysfunction. This study, however, suggested the possibility that renal tubular dysfunction caused by cadmium could be happened in Korea in the near future.
