본 연구에서는 청소년을 대상으로 우울, 대인불안, 학교적응이 휴대전화 중독에 미치는 영향을 검증하였다. 연구대상은 대전지역 소재의 중 고등학교 각 2개 학교의 중학생 249명, 고등학생 337명으로 총 613명이었다. 응답결과는 상관계수분석과 중다회귀분석을 실시하여 분석하였다. 그 결과는 다음과 같다. 첫째, 청소년의 우울, 대인불안, 학교적응, 휴대전화 중독간의 관계를 살펴보면, 강박과 학교친구적응을 제외하고는 모든 하위변인들 간에 유의미한 상관이 나타났다. 둘째, 중다회귀분석 결과, 휴대전화 중독을 가장 잘 설명해 주는 변인으로 우울, 학교친구적응, 대인불안이 나타났다. 본 연구결과는 우울, 학교적응의 하위 변인인 학교친구적응, 대인불안에 어려움을 보이는 청소년들의 휴대전화 중독 경향이 높은 것을 시사한다.

Objectives: This study was to identify the effect of physical therapy and related factors on depression in stroke patients. Methods: Questionnaires were completed by 46 stroke patients at physical therapy room in Busan Dongeui Medical Center from September 1999 to April 2001. The self·rating depression scale(SDS)was used to assess the differences for depression score in patients who had suffered a stroke. The design of this study was follow-up study between initial physical therapy and one month after initial. Results: A little decreased score(-0.17) was seen in patients treated with physical therapy in difference of depress between initial physical therapy and one month after initial, but there was no significant difference. In gender, male had -0.42 decreased score, female. on the contrary, had +0.09 increased score. Depress score for 50 years group was decreased(-2.08), but below 50 years and above 60 were increased in age (+1.25 and +0.27, respectively). There were no significant difference in weight, educational level, religion, side of paresis, and diabetes. Significant variables related to difference of depress in multiple regression analysis were weight(p=0.0082)and diagnosis(cerebral infarction, hemorrhage)(p=0.0473, R2=0.4241). Conclusions: This study was indicated that the more weight was a higher, the higher difference of depress score was. Difference of hemorrhage patients was smaller than that of infarction patients.

The perpose of this study is to report the effect of oriental demonstration treatment for Acne. Acne is an facial skin problems with depress, white head on the facial skin and bad smell. Objectives We experienced one case of Acne through acupuncture, cupping, herbal medication and herbal patch. 24 years old female patient suffered from acne with bad smell and depress. Method She was taken 23 times of acupuncture and cupping treatment, 30days of taking herb medicine and 7days for herbal patch(brand named Lee Myung Lae patch). Results After 23 times treatment her acne symtoms was improved. Conculusion Asian medical treatment could be safe and effective to American patient.

The effects of Sanjoinine-A, an alkaloid isolated from Zizyphus spinosus semens, on central nervous system and general pharmacology were studied. In summary, Sanjoinine-A depress the spontaneous locomotor activity without motor incoordination and it has slight analgesic effect. Those effects are qualitatively similar to that of diazepam but its potency is much lower than diazepam(20 times). Sanjoinine-A does not depress the electric or pentylenetetrazole induced convulsion. Those effects are dissimilar with that of diazepam. Sanjoinine-A slightly depress the spontaneous or acethylchollne induced motility of smooth muscles but degree of depressant effect was variable to tissues. Sanjoinine-A does not show any effects on digestive system, blood, kidney fuction and neural ganglion.

This paper describes the analysis of the operation of the switched snubber in order to depress the surge voltage in the MOS-FET inverter. In this paper, the N-channel MOS-FET which operates faster than the P-channel MOS-FET was used for the inverter circuit. So, the inverter and switched snubber can operate at high-frequency in the order of MHz. The cause of generating the surge voltage in the high frequency inverter has been cleared, and then how to depress the surge voltage using the switched snubber consisting of an N-channel MOS-FET has been given. Furthermore, described is the power loss within the switched snubber which is made of an N-channel MOS-FET. The inverter having the N-channel MOS-FET used as a switched snubber can drive such a low impedance load such as mega-sonic transducer for a mega-sonic studied cleaner sufficiently.

The purposes of the paper are to apply the axiomatic design methodology to the design of PBGA package with polyimide coating under hygrothermal loading in the IR soldering process and to suggest more reliable design conditions by stress analysis. The analysis model is a 256-pin perimeter Plastic Ball Grid Array (PBGA) package with the polyimide coating surrounding chip and above surface of BT-substrate. The polyimide coating is suggested to depress the maximum stresses occurred on the stress concentration positions. The axiomatic design methodology is proved to be useful to find the more reliable design conditions for PBGA package. Finally, the optimal values of design variables to depress the stress in the PBGA package are obtained.
