This study was following one of 'A study on the consciousness of fashion industries internship'. The purposes of this study were to develop the internship program which focused on practical use to introduce and carry out for fashion industries, and secondly to propose some regime for government to activate fashion internship. Reference searching method and depth interviewing method were used for this study. The results were as follows : Fashion industry internship was grouped into two classes, 'on-the-job training'; educating students fields and 'talent hunting'; selecting good persons. Internship of industry-academic world was classified into two types; the one is 'credit type' which has curriculums between universities and industries and the other is 'non-credit type' which has not any credit and is operated by industry own system. This study provided the development courses of pragmatic program to perform internship systematically and it also provided the program models for guide line in fashion industries. Six grades such as ready step, introduction step, selection step, management step, evaluation step and feed-back step were proposed for the internship program development steps of fashion industries. A virtual organization, 'The Fashion Industry and Academy Association' was proposed as a policy for activating internship between universities, industries and government.

Restructuring of electricity industry is going on for the purpose of introducing competition and after separation of generation and retail business and introduction of competition, substantial change is expected in overall electric power system. In other words, DSM projects are divided with public projects and private projects. Particularly for public project, it is essential to evaluate the DSM volumes by program. This paper tries to derive the ways for achieving the necessary DSM goal in the electricity industry in Korea. First of all, by analyzing the load in Korea, we forecast the standard demand and estimate the technological potentials of each program in considering DSM technological indicators. Moreover, by using economic analysis by program, we estimate economic potentials and finally, we estimate the potentials by program in considering the DSM policy. We estimate the potentials by using random method because application methodology and procedures by program are not established until now, which leads to not obtaining transparency for implementation effect by program. Therefore, this paper estimates the future potentials of DSM projects by using the logical and systematic analytic method and establishing database for DSM basic indicator. The DSM goals estimated by this method will be reflected to mid/long term nation-wide resource planning, which will mitigate anticipated power supply shortage and be applied to derive desirable energy demand/supply structure.

In current NAND flash design, one of the most challenging issues is reducing peak current consumption (peak ICC), as it leads to peak power drop, which can cause malfunctions in NAND flash memory. This paper presents an efficient approach for reducing the peak ICC of the cache program in NAND flash memory - namely, a program Cache Busy Time (tPCBSY) control method. The proposed tPCBSY control method is based on the interesting observation that the array program current (ICC2) is mainly decided by the bit-line bias condition. In the proposed approach, when peak ICC2 becomes larger than a threshold value, which is determined by a cache loop number, cache data cannot be loaded to the cache buffer (CB). On the other hand, when peak ICC2 is smaller than the threshold level, cache data can be loaded to the CB. As a result, the peak ICC of the cache program is reduced by 32% at the least significant bit page and by 15% at the most significant bit page. In addition, the program throughput reaches 20 MB/s in multiplane cache program operation, without restrictions caused by a drop in peak power due to cache program operations in a solid-state drive.

Purpose: This study was conducted to provide the fadamental information to prepare better Occupational Health Program for SSI based on the evaluation of the experience of nurse who were working in the Government-funded subsidized occupational health program for SSI. Method: The focus group method was used. Data was collected using focus group interviews and analyzed in the framework of the Grounded theory method as mapped by Strauss and Corbin(1990). The subjects were 14 nurses. Result: We identified 60 concepts, 30sub-categories and 6 categories(Table 1). Categories were Various services, Difficulties in implement Services, Successful strategies, Program Evaluation, Alternative Plans and Adaptation to new field. Conclusion: Nurses evaluated the effect of this program that autonomous health management ability has not changed although the possibility for the small scale industries to start the health management arose by acknowledging the importance of the health management of the workplace. In spite of many difficulties in implement services, nurses provided various health services using successful strategies. They suggest that various programs such as a model set-up suitable for the quality of workplaces and a role model set-up of the occupational health nurse for SSI as well as various efforts for the activated this program were needed. Nurses had a hard time in unfamiliar field when they began this program and overcame this difficulties with various strategies.

According to a survey by the Korea Tourism Organization in 2018 and 2019, traveling to places recorded in TV programs or influential videos has become an important travel trend and several studies show that watching a travel program improves the intention to visit the places featured on the program. This study designed a travel program-linked data service that provides additional information on the places and events to the viewers of the travel program. Specifically, the additional information of the travel program was defined in a formal manner by dividing it into places and events, and a method of exposure of the additional information conformed to the contents of the program was designed. We also devised an international standard DVB-based data transmission method that provides the additional information to data services appropriately in time for program broadcasting. This study is significant in that it tested new applications of data services for travel programs.

In a program that runs an engineering education certification, program outcomes refer to the knowledge, skills, and attitudes a student must have until graduation. In general, capstone design is used as a tool for evaluating program outcomes. This paper applies the intraclass correlation coefficient (ICC) to measure the raters' reliability in assessing program outcomes. Several raters evaluate program outcomes, and the result is used to obtain the raters' ICC. ICC measures the reliability of ratings or measurements for clusters - data that has been collected as groups or sorted into groups. If the ICC is close to 1, it means that the reliability among the raters is high. We evaluated the proposed method's usefulness through case analysis. As a method for assessing an evaluation tool's objectivity, multiple raters measure the same evaluation tool. As a result, we measured the ICC values for all POs, and analyzed the cause for the low measured POs. We applied this method to evaluate program outcomes of the Department of Computer Engineering in the past two years. As a result, we derived guidelines for improvement and program outcomes.

This paper presents a new method for the optimization of feed rate in sculptured surface machining. A NC verification model based on Z-map was utilized to obtain chip load according to feed per tooth. This optimization method can regenerate a new NC program with respect to the commanded cutting conditions and the NC program that was generated from CAM system. The regenerated NC program has not only the same data of the ex-NC program but also the updated feed rate in every block. The new NC data can reduce the cutting time and produce precision products with almost even chip load to the feed per tooth. This method can also reduce tool chipping and make constant tool wear.
