Phosphorylation on serine/threonine or tyrosine residues of target proteins is an essential and significant regulatory mechanism in signal transduction during many cellular and life processes, including spermatogenesis, oogenesis and fertilization. In the present work, we reported the isolation and characterization of mouse testis-specific serine/threonine kinase 5 (Tssk5), which contains four alternatively spliced variants including, Tssk5$\alpha$, Tssk5$\beta$, Tssk5$\gamma$ and Tssk5$\delta$. Moreover, the locus of Tssk5 is on chromosome 14qC3 and the four variants had a similar high expression in the testis and the heart; however, had a low expression in other tissues, except for Tssk5$\alpha$ which also had comparably high expression in the spleen. Each variant of Tssk5 expression began in the testis 16 days after birth. Aside from TSSK5$\alpha$, the other isoforms have an insertion of ten amino acid residues (RLTPSLSAAG) in region VIb (HRD domain) (His-Arg-Asp). Moreover, only TSSK5$\alpha$ exhibited kinase activity and consistently, a further Luciferase Reporter Assay demonstrated that TSSK5$\beta$, TSSK5$\gamma$ and TSSK5$\delta$ cannot be stimulated at the CREB/CRE responsive pathway in comparison to TSSK5$\alpha$. These findings suggest that TSSK5$\beta$, TSSK5$\gamma$, TSSK5$\delta$ may be pseudokinases due to the insertion, which may damage the structure responsible for active kinase activity. Pull-down assay experiments indicated that TSSK5$\beta$, TSSK5 $\gamma$ and TSSK5$\delta$ can directly interact with TSSK5$\alpha$. In summary, these four isoforms with similar expression patterns may be involved in spermatogenesis through a coordinative way in testis.

The purpose of this study is to explore the supporting scenario to promote vocational training in North Korea in terms of cooperation level. To this end, we have embarked on a regional and industry based vocational training program by predicting the political and social situation of North Korea and staging three scenarios systematically. These scenarios were designed originally based on the Futures Group methodology. The first scenario is to establish a technical training center in one area, focusing on the electrical, electronics, and clothing sectors. The second scenario is to set up a pilot campus of vocational training college in one region by selecting the electric, electronic, and automobile industries as its main industries. The third scenario is to establish five vocational training college campuses in North Korea, focusing on electricity and electronics, IT manufacturing, telecommunications, heavy industry, and women-specialized industries. We suggested the followings: First, establishing goals and strategies for North Korean vocational training and establishing road maps. Second, the North Korean vocational training governance system needs to be established. Third, R & D infrastructure for vocational training needs to be established. Fourth, HRD and HRM system in North Korea vocational training field needs to be established. In addition, the role of public and private employment services centers to provide them should be strengthening.

This study was conducted to examine the remuneration curriculum of vocational ability development training teachers and instructors and to examine ways to apply micro credentials. To this end, the current status of the remuneration curriculum of vocational ability development training instructors and instructors at K University's Competency Education Development Institute, the characteristics of micro credentials, and the possibility of linking the remuneration curriculum to micro credentials are as follows. First, most of the recognition of digital certificates was positive for digital certificates such as digital credit, digital badge issuance, and recognition of the recognized qualification process of maintenance education when completing the training course. In addition, as a method of applying micro credentials to conservative education, various cases were proposed to benefit from conservative education, systematization and grading of the qualification process, and credit of the qualification process. Second, as an institutional supplement to enhance the utilization of conservative education using micro credentials, the need to expand NCS-based major conservative education, provide efficient learning contents and learning methods, and set minimum completion time. In addition, the most common response as a way to improve the understanding of teachers and instructors in vocational ability development training was the micro credential promotion plan. Third, in the role of conservative education institutions and vocational ability development training instructors and instructors, conservative education institutions mention maintaining educational quality the most, and active participation was the role of vocational ability development training instructors. Through this study, it is expected to establish a vocational training environment that can enhance expertise and provide a practical portfolio of practical competency history by linking the remuneration curriculum of vocational competency development training instructors and micro credentials.

The analysis was the questionnaire consisting of 100 items and survey data. Results : 1. The satisfaction of the dental service for the disabled was respectively high which was the average of 4.49. 2. Their satisfactions of receiving kindness services by volunteers and employees were the highest in the entire research of successful handicapped dental services and it was 4.78 overall. 3. The satisfaction of using handicapped dental clinic has the higher range of female users than male's. In the mean time treatment details of the dental care and the satisfaction towards to the volunteers and faculty at the center show the statistical significance gap. 4. The oral care service after experiencing the dental clinic for handicapped relived their discomforts of using the regular dental clinic which shows their highest satisfaction as it is the point of 4.75. 5. the change perception after dental treatment for handicapped has the higher range of females than men's and solving the problems of mouth reference and discomfort of using regular clinics show the statistical significance gap. 6. In the change perception after having dental treatment for handicapped the thought of the possibility of periodical dental care shows the highest perception when the number of visiting is usually shorter and it shows the statistical significance. Conclusions : According to the satisfaction of those inpatients who use free dental care services that belong to dental clinics for handicapped in a part of Seoul welfare centers human services were appeared as the most important factor due to their advantages of taking services from volunteers and staff members. On the other hand to enhance the medical treatment information and environment which showed the weakest factors each inpatient should be specifically specialized for their needs and also further study on plans which enhance their perceptions toward to a better quality of oral-related life is required after using dental treatment service.

Objectives: The objectives of this study were to assess the implementation status of Health Promoting Schools (HPS) among elementary, middle and high schools and to identify characteristics of the schools that affect the implementation of HPS. Methods: A total of 703 teachers (male 32.2%, females 67.8%) from 70 elementary, middle and high schools in Seoul and Gyeonggi participated in the survey. A 60-item self-evaluation questionnaire was used to assess implementation status of HPS. Results: Implementation of HPS in elementary schools were more favorable than middle and high schools after controling for participants' characteristics, such as age, gender, and their duties at school (<0.001). Being a private school was associated with higher score on implementation of HPS in both elementary (${\beta}$=0.170) and middle/high schools (${\beta}$=0.275). However, being located in rural areas (${\beta}$=-0.409) and having larger number of students (${\beta}$=-0.521) were associated with lower score on implementation of HPS in middle/high schools. Conclusions: Middle and high schools, especially large public and/or rural schools, were less favorable in implementing HPS. Therefore, supporting those schools are necessary and developing evaluation and monitoring system for HPS implementation will contribute to promote students' health.

We propose a practical method for increasing formability of a sheet metal plate using laser heat treatment (LHT) and cladding process. In this work, two kinds of process such as laser-induced heat treatment and cladding were utilized to evaluate the effect on formability of SUS316 sheets with different thickness of 1 and 3 mm. By using a vertically line-patterned tensile specimen that was LHTed or cladded on its surface, the process parameters of each surface treating method were studied and optimized. Through the basic test, we knew that the laser power of 900 W and scanning speed of 500 mm/min was the best condition for increase of formability. As the treatment results, ultimate tensile strength and elongation were increased as approximately 2.1 and 7.0%, respectively. To verify the usefulness of this work in industrial cases, we conducted a bulging test using with and without LHTed SUS316 sheet metal blanks. The results show that the bulging height of LHTed sheet was increased by 73% compared to that of the original one.
