After the synthesis of IL-15 cDNA from the total RNA of mouse spleen, it was inserted into the prokaryotic expression vector, pRseta, and eukaryotic expression vector, pcDNA3.0, respectively. Subsequently, the insertion of gene and open reading frame were confirmed by sequencing of each plasmid, respectively. Using pRseta- IL-15 plasmid, the recombinant IL-15 protein was induced by IPTG under BL21 (DE 3) host cells and recombinant IL-15 was expressed at 14.5 KDa with time. Then, IL- 15 was separated by His-tag affinity chromatography and analyzed by SDS-PAGE to yield soluble IL-15 at 14.5 KDa as monomer and 29.0 KDa as dimer. In order to inspect the function and contribution of IL-15, the in vitro experiment was established using mononuclear cells separated from the mouse spleen. After 48h exposure of PHA to mouse splenocyte and 24h treatment with recombinant IL-15, the effects of cytokine inductions inspected against IL-2, IL-6, IL-10, IL-12, IFN-r, and GM-CSF. The results showed that comparing with the control, IL-6 increased, IL-2, IL-12 and IFN-r increased and similar, and GM-CSF decreased. In addition, the direct injection of pcDNA3.0-IL-15 plasmid into mice gave the similar results to in vitro studies. Namely, IL-6 and IL-12 increased, and IL-2, IFN-r and GM-CSF were similar or decreased. IL-10 was not induced in in vitro and in vivo experiments. These results suggested that the IL-15 induce the splenocyte activation and can be an important factor in proliferation and fuction recovery of weakened T-cell.

This study conducted to evaluate the association of work posture with cervical spine abnormality toward 106 microwave-oven assemblers. A self-administered questionnaire was used to obtain a general characteristics and a work history of workers. The posture of neck and shoulder joint of workers were measured with video tape recording and the simple X-ray of cervical spine was checked-up to observe the X-ray abnormality including degenerative change, curvature abnormality, disc space narrowing or disc canal narrowing. The result were as follows. 1. The prevalence of degenerative change among cervicobrachial disorder workers was 44.3%(47 persons), curvature abnormality was 43.4%(46 persons), disc space narrowing was 21.7%(23 persons), and disc canal narrowing was 21.7%(23 persons). 2. The prevalence of degenerative change at cervical spine was increased with the degree of neck flexion(flexed versus neutral; odds ratio (OR)=2.7), the total work posture of neck(mild or severe awkward versus neutral; OR=1.2, 3.4). 3. The prevalence of degenerative change at cervical spine was increased with the degree of the right shoulder flexion, the heaviness of the materials carried by the right hand and the degree of awkwardness at the total work posture of right shoulder(p<0.05). 4. There was no evidence of association between curvature abnormality, disc space narrowing, disc canal narrowing and work posture. In conclusion the awkward work posture was related with degenerative change of cervical spine among microwave oven assembling workers and the further study in these field must be made to prove the association objectively.

BACKGROUND: Hepatitis B vaccination schedule commonly used in Korea is divided largely into 0, 1, 2 month scheduled vaccination group(0, 1, 2 group) and 0, 1, 6 month scheduled vaccination gorup(0, 1, 6 group). The only difference bet.ween two groups is the interval from 2nd dose to 3rd dose. This st,udy had been carried out, to find whether t.he difference of vaccination interval influence the vaccination complet,ion rate or not. METHODS: Study objects are 135 persons over 20 years old who had heptitis B vaccination more than once in injection room of Dongkuk University Kyong-ju Hospital from Jan. 1st in 1996 to Dec. 31th in 1996. Data about vaccination completion were gathered from record book of injection room and telephone interview. RESULTS: Hepatitis B vaccination completion rate is 73.8% in 0, 1, 2 group and 72.5% in 0, 1, 6 group. The reasons for incomplete vaccination are forgetting vaccinat.ion date(36.4% in 0, 1, 2 group and 50% in 0, 1, 6 group), having no time to spare for vaccination(54.5% in 0, 1, 2 group and 43% in 0, 1, 6 group) and knowing positive HBsAb before completion of scheduled vaccination(9.1% in 0, 1, 2 group and 7% in 0, 1, 6 group). CONCLUSIONS: There is no difference in Hepatitis B vaccination complet,ion rate bet.ween 0, 1, 2 group and 0, 1, 6 group.

Purpose: This study aimed to understand the keywords and major topics of the educational goals and objectives of nursing educational institutions in South Korea. Methods: From May 10 to May 20, 2022, the educational goals and objectives of all 201 nursing educational institutions in South Korea were collected. Using the NetMiner program, degree and degree centrality, semantic structure, and topic modeling were analyzed. Results: The top keywords and semantic structures of educational goals included ‘respect for human (life)-spirit-science-based on, global-competency-professional nurse-nursing personnel-training, professional-science-knowledge-skills, and patients-therapeutic care-relationship.’ The educational goals’ major topics were clients well-being based on science and respect for human life, a practicing nurse with capabilities and spirit, fostering a nursing personnel with creativity and professionalism, and training of global nurses. The top keywords and semantic structures of the educational objectives included ‘holistic care-nursing-research-action-capability, critical thinking-health-problem solving-capability, and efficiency-communication-collaboration-capability.’ The educational objectives’ major topics were ‘nursing professionalism, communication and problem-solving capability; a change of healthcare environments and a progress of nursing practices; fostering professional nurses with creativity and global capability; and clients’ health and nursing practice.’ Conclusion Educational goals in nursing presented specific nursing values and concepts, such as respect for human life, therapeutic care relationships, and the promotion of well-being. Educational objectives in nursing presented the competencies of nurses as defined by the Korean Accreditation Board of Nursing Education (KABONE). Recently, the KABONE announced new program outcomes and competencies, which will require the revision of educational goals. To achieve those educational objectives, it is suggested that the expected level of competencies be clearly defined for nursing graduates.

We studied cervical cytology of 175 cases of histologically confirmed microinvasive squamous cell carcinoma of the uterine cervix in Cheil General Hospital from 1991 to 1993. Excluding 32 cases of insufficient smear, 143 cases were reviewed in view of background, cellularity, smear pattern, nuclear chromatin and presence of nucleoli. The characteristic findings of microinvasive carcinoma were syncytia and/or individual tumor cells in the focally necrotic inflammatory background. Nuclear chromatin was clear or fine. Nucleoli were observed in 55%. The prediction rate of microinvasive carcinoma was 74%. There is no significant relationship between the cellular features and depth of invasion.

OBJECTIVES: The challenge of an increasing elderly population has coupled with everpresent social concerns in Korea. A major problem in health center for the frail older people is that medical, healthcare, and welfare services are often fragmented in terms of providers and settings without appropriate coordination. The purpose of this study was to investigate the need of health center-based integrated healthcare services and its related factors for the elderly. METHODS: A total of 110 elderly people who had visited at a county Health Center were interviewed using a self-administered questionnaire from November to December, 2005. The questionnaire consists of five domains according to the Program of All-inclusive Care for the Elderly. RESULTS: Respondents had high need (total mean score with the 5-point Likert-type sacle: 3.67) of health center-based integrated healthcare services including home visiting service (mean: 4.08), chronic disease care service (mean: 4.06), and transportation service (mean 4.05). According to the results of hierarchical multiple regression analysis, among three regression models the magnititude of the variance of full model that is explained by the need of welfare-domain service was significantly larger than two reduced model. Income was a significant variable in increasing the need of health care and welfare services. CONCLUSIONS: This study suggests that the health center-based integrated healthcare services for the elderly must be continuously developed and provided for the health promotion and improved the quality of life of the elderly who live in rural area in Korea.
