This study was conducted to confirm the effectiveness of the simulation-based orientation program for students preparing for clinical practice in child nursing for the first time. A quasi-experimental non-equivalent control group, pre-posttest design was used. The subjects were 70 3rd grade nursing students who started clinical practice. The simulation-based orientation was applied to 35 students in the experimental group, and the existing lecture style orientation was applied to 35 students in the control group. Data collection was conducted on the nursing competence, perceived stress, self-efficacy, and communication skills before and after orientation. The collected data were analyzed using the SPSS WIN 23.0 program. As a result of the study, the simulation-based orientation program before child nursing practice of nursing college students was found to improve nursing competence (t=5.390, p<.001). Perceived stress, self-efficacy, and communication skills all increased after practice, but were not statistically significant. Therefore, it is necessary to fully consider the situation of students when constructing and operating the contents of the simulation-based orientation.

본 논문은 워터마크의 일반 요건 중에서 가장 기술적으로 요구되는 강인성과 비인지성을 함께 발전시키기 위해서 구성되었다. 먼저, 주파수 영역을 이용한 워터마킹 기법 중에서 현재 압축 표준에서 사용되고, 지역적 인간 시각 시스템을 이용할 수 있기 때문에, 널리 사용되는 블록 단위의 DCT를 사용한다. 삽입 위치를 결정하기 위하여, 기존에 발표된 논문들의 강인성을 비교하여, 보다 나은 위치를 선정한다. 그리고, 인간 시각 시스템 중에서, 강한 에지의 인지성을 줄이기 위하여, 에지의 오리엔테이션을 보존하고 수평과 수직 성분보다는 45 도에 가까운 DCT 대각 성분에 워터마크의 강도를 높여준다 이는 워터마크 이후의 강한 에지 성분의 오리엔테이션 오차를 줄여주며, 에지의 비인지성을 향상시키는 결과를 가져온다.

BGA 409 chip currently the most as a visual inspection of the exterior inspection is conducted. Human depending on visual inspection of the exterior inspection of the current state of testers, depending on how the test results because the change is difficult to expect reliable results. Therefore, the challenges of visual inspection of BGA solder balls to improve the visual inspection technique was developed. However, BGA solder ball size of the microstructure and the characteristics of the distinction between hard test the accuracy of the fall orientation error has a problem. In this paper BGA solder balls exterior inspection of the accuracy to improve the edge detection algorithm, the complement of features and only the comparison proposed a pattern-matching techniques, based on the characteristics of spatial configuration of the area by improving the standard error of the orientation proposed improvements.

The biggest challenge of managing mobile interpretative device is that visitors do not have the mobile experience. Thus, in the research of the mobile application of the Leeum (Samsung Museum of Art), a short orientation session as a treatment was provided to survey participants to make them use of a mobile experience. The orientation solved the problem of hesitancy of using smartphone in other researches, it was simultaneously the uniqueness of the methodology. Based on the research data, their satisfaction with visiting experience and with using the application appeared to be relatively high. A half of participants used the application for 10 minutes which is accounted for 20-30% of the total viewing time. Participants (80.3%) engaged in each exhibit with the application in less than 30 sec.-1 minute. Comparing with the average time of engagement (10-30 sec.) for each exhibit without using mobile applications, it is possible to conclude that the mobile application notably contributed to make participants engage with exhibits longer.

The purpose of this study was to propose information services for people with disabilities in the culture and art complex. As a research method, group interviews were conducted. Data were collected from three different groups of people with physical disabilities, hearing impairments, and visual impairments in order to investigate specific information services for these groups of people. The results of the information services needed were indicated, based on four sections: the center web pages, information desk, orientation area, and information search area. Specifically, the results showed that more active supports would be provided at the information desks for people with hearing impairments and visual impairments as well as facilities for people with physical disabilities. In the orientation area, special equipment would be provided for people with hearing impairments and visual impairments, and exclusive seats for wheelchair users. For further studies, a detailed research about the information behavior for visitors with disabilities in the culture and art complex would be needed.

The introduction of the communicative approach in the English language education brings in a Korean the English Program in Korea (EPIK), which is a Korean government sponsored program established 1995. by the Korean Ministry of Education improve Korean students' and teachers' communicative competency in English within the public school system in Korea. For this goal, EPIK invites English speakers from 7 major English-speaking countries. However, the effectiveness of this program has been questioned in Korea. Thus, the objective of this paper is to explore the current status, problems, and the directions for the program to be aimed at, and for the effectiveness of EPIK through investigation of the program. Then this paper presents some possible solutions and suggestions including the possibility of VR use in orientation and training programs in order to empower both Korean teachers of English and English native teachers in Korea.

모바일 기기의 폭발적 증가세로 인해 플래시 메모리의 수요가 증가하고 있다. 낸드 플래시 메모리는 적은 전력 소모량과 높은 전기적 효율 때문에 많은 많은 연구가 이루어지고 있다. 반면에 stress-induced leakage current, positive-charge-assisted tunneling, thermally-assisted tunneling 등의 문제로 신뢰성이 저하되는 문제가 발생한다. 프로그램/이레이즈 동작이 반복되면 소자에서 발생하는 에러의 발생비율이 늘어나 신뢰성이 저하되게 된다. 비록 신뢰성 저하 메커니즘에 대한 연구가 많이 이루어졌으나, 워드라인 스트레스에 의한 프로그램 특성 저하에 대한 구체적인 연구가 진행되지 않았다. 본 연구에서는 플래시 메모리의 워드라인 스트레스로 인한 전기적 특성 감소 현상을 보기 위해, 플로팅 게이트의 두께를 변화시키면서, electron density와 depletion region 의 변화를 관찰하였다. 낸드 플래시 메모리의 전기적 특성을 멀티 오리엔테이션 모델을 포함한 3차원 TCAD 시뮬레이션을 이용하여 계산하였다. 프로그램/이레이즈 동작이 증가함에 따라, 플로팅 게이트에 공핍영역이 생기고, 블로킹 옥사이드와 게이트 사이에 의도하지 않은 트랩이 생기게 된다. 이로 인해 프로그램/이레이즈 동작이 증가함에 따라, 플로팅 게이트의 electron density가 감소하는 경향을 보았다. 이 연구 결과는 낸드 플래시 메모리 소자에서 신뢰성을 향상시키고 프로그램 특성을 증진시키는데 도움이 된다.

Purpose: The purpose of this study was to understand the experiences and problems of sexual and reproductive health among Korean lesbian, gay, bisexual, transgender, queer or questioning, and intersex (LGBTQI) people. Methods: Phenomenological methodology was employed in this study, which comprised 14 LGBTQ participants. Data were collected using individual in-depth interviews from May to June, 2021, and were analyzed using Colaizzi's method. Results: Four categories-comprising nine theme clusters-emerged from the data, as follows: 1) hard-to-recognize gender identity, 2) blind spots in the healthcare system, 3) empathy and support in the community, and 4) new challenges to protect my precious self. Conclusion: This study provides valuable and detailed insights into the meaning of sex and reproductive health among Korean LGBTQI people. This finding could be utilized to develop effective questions for understanding not only sexual and reproductive health but also overall health problems of LGBTQI people.

The purpose of this paper is to in vestigate a relative effectiveness of instruction among such three orienting methods as lecture, slide-tape and video-tape which the library of Duk Sung Women's University has applied for orienting the freshmen for the last three years. This research also carried out a sample survey by distributing uniform questinnaire to the three different groups of the students. Each group was oriented with lecture, slide-tape and Video-tape respectively. Finally, the empirical findings of this research are as follows: 1. All three orienting methods were useful for students to improve knowledge as to how to use the library, 2. There were a wide difference in effectiveness among three instructional methods, obviously, the slide-tape method was more effective in the orientation than the lecture method and, furthermore, the video-tape was more effective than the slide-tape one, Therefore, it seem safe to conclude that the media utilization effective in orientation program should be encouraged by the university libraries of Korea.
