Although monitoring of radon has been extensively implemented throughout South Korea, the risk assessment has been mainly limited to indoor environments such as schools, workplaces, and multi-use facilities, and evaluations have normally been performed separately. In this study, the differences in radon exposure according to two groups (< 1 and 1-6 years old) were evaluated considering various indoor and outdoor environments, timeactivity patterns, variations in radon concentrations, and dwelling type (single detached and apartment house) using Monte-Carlo simulation. The distribution and representative values of radon concentration by micro-environments were confirmed through the Anders-Darling test, and a uniform distribution was applied in case of uncertainty. The effective dose ranged from 1.81 ± 1.19 to 2.81 ± 3.02 mSv/y. Comparing the levels recommended by EPA, WHO, and ICRP with the value of the 95th percentile of this study, it was found that the results for those dwelling in detached houses exceeded recommended levels. Infants that spend a lot of time in homes with relatively high levels of concentration of radon are assessed to be somewhat more vulnerable to radon exposure. .

Background: As ways to optimize the mobilization of postural stability muscles for sitting up motions, arm reaching motions and head raising motions have important effects. Objectives: This study was conducted to investigate the effects of reaching to sit-up training on the trunk muscle activity, postural ability, and balance ability of patients with hemiplegia due to stroke. Design: Randomized controlled trial. Methods: This study was conducted with 18 stroke patients who met the selection criteria divided into two groups: a study group of 9 patents and a control group of 9 patients. The study group carried out reaching to sit-up training, which can promote trunk muscles and improve control through trunk interactions. The control group received general physical therapy intervention Results: The activity of the trunk muscle was significantly different before and after intervention in study and control group. The functional reaching test showed significant changes in both the study group and the control group. The timed up and go test showed a significant change in the study group. Conclusion: Reaching to sit-up training for 4 weeks showed increases in trunk muscle activity in stroke patients and was effective in improving balance ability.

The purpose of this study was to examine the organization socialization process of engineering novice for the learning and adaptation. Qualitative case study was performed with 5 participants and the collected qualitative data were analyzed using funnel-like method. The findings showed that the organization socialization process proceeds in three steps–anticipatory, encounter, and metarmorphosis. Engineering Novice look at the whole organization socialization proces of organization culture and job maladjustment, and the relationshipbetween internal and external organizations to overcome the difficulties arising from the community through the process of becominga full participant. Socialization of engineering novice is ultimately the organization to respond to new situations and changes in thelearning process takes place in the process, talking about a major resource for human resources. This enables organizations to socializeand harmonious human relationships within the organization so that it can be more important than anything else.
국내 상장기업을 중심으로 퇴직급여부채 산출시 적용할인율에 관한 연구 - 적용 채권 및 적용방식의 적합성과 적정 부채증가율 제안

국내 상장기업의 퇴직급여부채는 한국채택국제회계기준(K-IF RS)에 서 확정급여채무로, 법인세법에서는 퇴직급여충당금으로, 근퇴법에서 는 계속기준책임준비금으로 명칭을 달리하고 있다. 퇴직급여부채는 보 험수리적가정이 반영되어 산출된다. 가정 중 할인율은 퇴직급여부채의 주요 결정요인으로 작용한다. 할인율은 회계기준과 근퇴법에서 할인율 과 예상이율로 다른 적용 기준을 가지고 산출하고 있다. 부채의 규모 와 원가가 달라지는 가장 큰 원인이다. 본 연구는 할인율과 예상이율의 한국적 적용 우위성을 실증적으로 분석하였다. 확정급여채무의 순환모형을 통해 퇴직급여부채증가율을 도출하여 연구모형으로 사용하였다. 예상이율과 할인율의 적용방식을 서로 교차시켜 적합성을 검증하였다. The retirement benefit obligations of domestic listed companies have different names in different laws; the defined benefit obligation in the K-IFRS, the retirement allowances in the Corporate Tax Law and reserves on the going concern basis in the Employment Retirement Benefit Security Law. The actuarial assumptions are applied when calculating the retirement benefit obligations. The discount rate in the assumption is one of the major factors in the retirement benefit obligation decision. We used the growth rate of the retirement benefit liabilities derived from the circulation model of the defined benefit obligation as a research model. We cross-checked the application methods of the expected interest rate and the discount rate to evaluate the adequacy.
