  • Reference electrodes are generally implemented for the purpose of monitoring the cathodic protection potentials of buried or immersed metallic structures. In the market, many types of reference electrodes are available for this purpose, such as saturated calomel, silver/silver chloride and copper/copper sulfate. These electrodes contain a porous ceramic junction plate situated in the cylindrical body bottom to permit ionic flux between the internal electrolyte (of the reference electrode) and the external electrolyte. In this work, the copper/copper sulfate reference electrode was modified by replacing the porous ceramic junction plate for a metallic platinum wire. The main purpose of this modification was to avoid the ion copper transport from coming from the inner reference electrode solution into the surrounding electrolyte, and to mitigate the copper plating on the coupon surfaces. Lab tests were performed in order to compare the performance of the two mentioned reference electrodes. We verified that the experimental errors associated with the measurements conducted with developed reference electrode would be negligible, as the platinum surface area exposed to the surrounding electrolyte and/or to the reference electrolyte are maintained as small as possible.

  • In multi-purpose lathe, the design of tilting turret slide system has on important and critical role enhance accuracy of the machining process. Tilting turret unit is traveled by 3-axis slide systems. There is a need to design this part very carefully. In this research, 3-axis sliding system with tilting turret is modeled by considering the element dividing, material proprties, and boundary conditions using MSC/PATRAN. Mode and frequency analysis of each structures such as saddle, careg, and turret are simulated by MSC/MASTRAN, for the purpose of developing the effective design.

  • The purpose of this study is to review histoiral development of Gye from the home welfare point of view. The origin of gye can be found ancient primative society but it was widely organized middle of{{{{ {Y }_{1 } }} }} D ynasty of Gye was originally wellfare o r ganization but changed to financial organization later. Gye can be classified as an organization 1) to realize common purpose as a whole community & 2) to realize common purpose as a household or individual Home wellfare function of Gye are studied on 8 areas,. In order to revitalize original Gye spirit in he modern society following was suggested: 1) For the rural village to be unified under Durae's spirit and organize Farming Company; 2) For the urban community to link needy people's Gye and above middle class people's Gye and utilize as civil wellfare organization ; 3) For financial organizaton to develop a pool financial product.

  • Purpose: The purpose of this study was to develop an integrated suicide violence prevention program for adolescents. Another purpose was to evaluate the effects of the integrated suicide violence prevention program on self-esteem, parent-child communication, aggression, and suicidal ideation in adolescents. Methods: The study employed a quasi -experimental design. Participants for the study were high school students, 24 in the experimental group and 25 in the control group. Data was analyzed by using the SPSS/WIN. 11.5 program with $X^2$ test, t-test, and 2-way ANOVA. Results: Participants in the integrated suicide violence prevention program reported increased self-esteem scores, which was significantly different from those in the control group. Participants in the integrated suicide violence prevention program reported decreased aggression and suicidal ideation scores, which was significantly different from those in the control group. Conclusion: The integrated suicide violence prevention program was effective in improving self-esteem and decreasing aggression and suicidal ideation for adolescents. Therefore, this approach is recommended as the integrated suicide violence prevention strategy for adolescents.

  • Java 프로그램밍 언어는 general-purpose concurrent object-oriented 언어로 알려져 있다. Java 언어는 개념과 구문 모두가 매우 간결하고 통일되어 있으며 인터넷 환경에서 최대한 활용되도록 하기 위하여 가상기계 개념을 도입하여 목적코드를 생성한다. 프로그래밍 언어에서 가장 중요한 부분이 data type 부분이다. Java 언어는 primitive type과 reference type을 지원한다. Primitive type과 reference type을 지원한다. Primitive type에는 boolean type integral type이 있다. Integral type에는 character, byte, short integer, integer, long integer, single-precision 과 double-precision floating point number가 있다. Reference type에는 class type, interface type, array type이 있다. 그러나 Java 언어는 general-purpose 프로그래밍 언어가 일반적으로 지원하는 structure type을 지원하지 않는다. 대신에 class type이 structure type을 포함하여 지원하는 구조로 되어 있다. 그러나 class type과 structure type은 서로 상이한 data type으로 판단된다. 따라서 Java 언어가 general-purpose의 성격을 가지기 위해서는 structure type을 명시적으로 지원하는 것이 바람직하다고 생각된다. 이 논문은 structure type을 Java 언어에 포함시킬 것을 제안한다.

  • The KOMPSAT-1(Korea Multi-Purpose Satellite-1) is the first multi-purpose satellite funded by Korean government for the purpose of remote sensing and scientific data gathering in KOREA. It has successfully achieved its own mission since Dec. 21, 1999. This paper provides an overview of the KOMPSAT-1 missions and addresses the nominal mission planning and operation flow. This paper also describes the routine operational orbit determination and orbit prediction process using GPS navigation solution data. Meanwhile, some problems due to inexperience of the multiple mission operations during LEOP(Launch & Early Orbit Phase) and early normal mission were investigated. Then, resolutions that include the development of new mission planning tool are addressed. The KOMPSAT-1´s missions become more complicated rather than its Initially designed ones.

  • The internet is one of the modern facilities that has been diffused very rapidly in recent years and tremendously influenced on our life. Although the adolescents are major users of internet, the literature in clothing and textile area has not addressed the relationships between adolescents' internet use and clothing behavior, The purpose of this study was to examine the differences of adolescents clothing behavior. purchase evaluative criteria, and information source according to the use of internet. Descriptive statistics, t test, Analysis of Variance (ANOVA), and Duncan test were employed to analyze the data collected from the convenience sample of 572 middle and high school students in Gyeongnam, Korea. The use of internet was partially related to the adolescents' clothing behaviors. purchase evaluative criteria. and information source. Also, it was observed that the frequency and purpose of fashion website tended to be related more than the amount and purpose of internet did. Marketing implications from the results were suggested.
