오익수,우경근 한국상담학회 2005 상담학연구 Vol.6 No.2

This study is to identify the psycho-social factors related elementary children's computer game addiction. It was assumed that self-efficacy, impulsiveness, stress, parents-children relations and peer-relations were factors which were related to computer game addiction. This assumption was established by Oh (2003)'s previous study and this study was to confirm the assumption statistically. Data were collected from 500 elementary children in 5th and 6th grades. The results of the study have showed followings; 1) Subjects were classified into three sub-groups:addicted group (7.1%), boundary group (16.2%) and normal group (77.0%). 2) ANOVA have showed that there were significant differences among the groups in self-efficacy, impulsiveness, stress, parents-children relations and peer-relations. 3) Multiple-regression have showed that self-efficacy, impulsiveness and stress were statistically significantly included in regression equation on computer game addiction. 본 연구는 초등학생의 컴퓨터 게임중독과 관련한 심리․사회적 요인을 탐색하는 것이다. 이는 오익수(2003)가 가설적으로 제안한 초등학생 인터넷 중독의 심리적 요인들을 경험적으로 확인하는 절차를 통하여 이루어졌다. 오익수(2003)은 초등학생의 인터넷 중독의 심리적 요인으로서 친구관계, 가족관계, 충동성, 자아개념, 스트레스를 제안하였는데, 이들 요인 중 자아개념을 자아효능감으로, 가족관계를 부모자녀관계로 대체하여 컴퓨터 게임 중독과의 관련성을 경험적으로 확인하였다. 이는 비교적 적은 문항으로 구성된 척도를 사용하여 가설적으로 초등학생의 인터넷 중독을 설명했던 오익수(2003)의 연구 결과를 보다 정련된 척도를 사용하여 통계적으로 확인하려는데 의의가 있다. 자료는 광주광역시 소재 초등학교 5,6학년 500 명을 대상으로 수집되었고, 변량분석과 중다회귀분석을 통하여 컴퓨터 게임 중독과 관련있는 요인을 탐색하였다. 연구결과, 컴퓨터 게임중독수준에 따라 자아효능감, 충동성, 스트레스, 부모자녀관계, 친구관계에서 통계적으로 유의한 차이가 있었고, 컴퓨터 중독 정도에 영향을 주는 요인은 자아효능감, 충동성, 스트레스와 같은 개인적 특성에 관한 요인이 유의한 변인으로 확인되었다.

Traditionally the powder polymer has been used in the sewage sludge treatment and water purifying plants. The powder polymer, however, has several problems such as bad working condition by dispersed powder and unstable operation of dehydrator by a lump of undissolved polymer. In this study, high accuracy automatic dissolving system for emulsion polymer is developed to reduce the cost of facility and is suitable for unit-process automation. This system is consist of the emulsion polymer storage tank, polymer dissolving solution supply tank, mixing chamber, micom and mobile system, etc. Performance tests for the system such as the rated flow of flowmeter, quantity of the tube pump, solubility of the mixing chamber, accuracy of micom and mobile system have been performed. The performance of the prototype system satisfies all the objects of this study.

Eliminating the moldings bad problem such as weld line, burn, shot short, burr, flow mark, jetting, silver streak, black streak and bubble, and so on caused by interference a mold and a product in designing a mold for in injection molding processes is a very important problem. In general, the moldings bad problem can be avoided by side cores which are the principal members of a mold assembly. The objective of this study is to develop a mold structure with a harmonica core and vacuum system. This mold can decrease the effects of the various deficiencies such as weld line, burn, shot short, burr, flow mark, jetting, silver streak, black streak and bubble, and so on in injection molding. To derive the optimal position and dimensional constraints of the harmonica core and vacuum system, experiment or numerical analysis was performed under normal process conditions.

Wire rods having various sectional shape are generally used directly in various applications. In the shape rolling, a couple of grooved rollers are used and the groove match the sectional shape of the wire rod. In this 2 roll system, a couple of rollers must be changed whenever the sectional shape of the wire rod is changed, and the frequent changes of roller cause rise of manufacturing cost. We developed a 4 roll wire rolling mill that reduce the disadvantage of 2 roll rolling, at the same time improving quality of the wire rods and reducing production costs. The present work is focused on the development of a high precision 4 roll wire rolling mill for the wire rods that have various rectangle sectional shape.

초등학생 인터넷 중독 상담 모형 개발

오익수,김현희 한국상담학회 2004 상담학연구 Vol.5 No.1

This study was to develope the counseling model for elementary children’s imternet addiction. The literature related to prevention and modification of internet addiction was reviewed. The guidelines and the implications for counseling internet addiction were induced, and were applied to preventive counseling on 15 elementary children. Effective counseling strategies were induced through this counseling process, and Counseling program for inrenet-addictive elementary children was developed. Then this counseling program was applied to 5 elementary children and the effectiveness of the program was tested. This study suggested that the factors as follows were effective for counseling on internet-addictive elementary children:1)the awareness of the level of internet addiction, 2)the rapport with the teacher(counselor), 3)supportive network with peers, and 4)development of the behavioral checklist with parent and application of self-management techniques. 본 연구는 초등학생 인터넷 중독의 상담 모형을 개발하기 위한 것이다. 이를 위해 인터넷 중독의 예방과 교정 전략에 대한 기존 문헌을 검토하여, 인터넷중독 상담을 위한 지침과 시사점을 정리하였다. 이러한 지침과 시사점을 15명의 초등학생을 대상으로 한 인터넷 중독 예방 상담에 적용하여, 효과적인 상담전략을 추출하고, 이를 기초로 초등학생 인터넷 상담 프로그램을 구안하였다. 상담프로그램은 5명의 초등학생들에게 적용하여 그 효과를 검증하였다. 본 연구를 통하여 초등학생 인터넷 중독 상담을 위하여 1)인터넷 사용 수준의 인식, 2)교사(상담자)와의 친밀감 형성, 3)또래와의 지지체제, 4)부모와 함께한 자기행동목록의 작성과 자기관리기법의 적용 등이 효과적이었음을 논의하였다.

In this paper, a new technique to reduce the phase noise in microwave oscillators is proposed using the resonant characteristics of the Photonic Bandgap(PBG). We applied PBG structure to ground of the microstrip line resonator with the low Q(Quality factor). Therefore, we improved about 10 dBc in contrast to phase noise characteristic of the conventional microstrip line oscillator at 2.4 GHz @100 MHz offset. Output power is 7.09 dBm. 본 논문에서는 T-Junction 스위치 구조를 이용하여 이중 대역 전압제어 발진기를 설계, 제작하였다. T-Junction 스위치는 이중 대역 공진을 얻기 위한 스위치로서 공진부에 적용된다. 설계한 공진기를 발진기의 능동부와 결합하여 이중 대역 전압제어 발진기를 만들었다. 상위 주파수 대역 5.715 GHz 에서 전압제어 발진기의 출력 전력은 -1.42 dBm, 위상잡음은 1 MHz offset에서 -94.37 dBc/Hz이고 하위 주파수 대역 2.236 GHz에서 출력 전력은 -2.09 dBm, 위상잡음은 1 MHz offset -104.78 dBc/Hz 이다.

The EMI shield material with narrow width has some deficiencies in shielding capability and this deficiencies are caused by the inconsistent relationship between the inductance and temperature after heat treatment. This study is performed to develop a nano crystal magnetization heat treatment process technology and design a EMI shielding material with wide width up to 350mm. As a result, the performance of the developed wide EMI shield material satisfies all the objects of this study such as the inductance, thickness, permeability, ribbon productivity, lamination productivity. Also, we find that this wide EMI shield material can be used effectively for the EMI shield room, large medical equipment and so on.
