여행사종사원들의 진로준비행동과 진로적응성 간의 영향관계 분석
김종상(Kim, Jong-Sang) 한양대학교 관광연구소 2018 觀光硏究論叢 Vol.30 No.4
본 연구는 여행사종사원들의 진로준비행동과 진로적응성 간의 영향관계를 분석하여 여행기업의 인적자원개발에 시사점을 제공하기 위한 목적으로 수행되었다. 연구방법은 정량적 연구방법을 선정하여 회귀분석 방법으로 분석하였다. 그 결과, 도구준비행동을 제외한 정보수집행동과 목표달성행동이 진로적응성의 목표의식, 대인관계, 직무능력, 긍정적 태도에 영향을 미치는 것으로 나타났다. 여행사종사원들은 진로준비과정에서 실무학습을 수행하는 것 보다, 여행사 직업관련 정보수집행동과 입사지원, 면접수행 등을 의미하는 목표달성행동을 중요하게 인식하고 있었다. 이러한 결과로부터 정보수집행동과 목표달성행동은 단순히 채용정보만을 수집하고 여행사를 선택하여 입사지원등을 수행하는 것이 아니라 변화하는 직무특성과 기업의 특성을 체험하는 행동으로 정의될 수 있음을 인식할 수 있었다. The purpose of this study was to analyze the relationship between career preparation behavior and career adaptability of travel agency employees to provide implications for the development of human resources for travel companies. To empirically test the data, regression analysis was used. The results showed that information collection behavior and goal attainment behavior, excluding tool preparation behavior, affect the sense of goals, interpersonal relationships, job competency, and positive attitude. Rather than conducting major study in preparation for the career path, travel agency employees were aware of the importance of collecting about job information related to travel agency, applying for employment, and conducting interviews. From these results, information collection behavior and goal attainment behavior can be defined as an act to experience changing job characteristics and corporate characteristics rather than simply collect employment information and select travel agencies to provide job support.
Comparative Analysis of the Vulnerable Period of Groundwater Level Drawdown
이재범,양정석 대한토목학회 2020 KSCE JOURNAL OF CIVIL ENGINEERING Vol.24 No.11
This study selected groundwater level as the factor to represent the changes in groundwater resources and developed an evaluation method for the management of monthly groundwater level considering the temporal variability with the target of 9 sub-basins located in the Namwon. For the evaluation of vulnerable period in the groundwater level considering the influence of rainfall on the underground aquifer, the following methods were used: applying effective rainfall amount based on the application of rainfall data, and using rainfall data with the notion of critical infiltration, among which vulnerable periods were compared for evaluations. A standard was developed for evaluating groundwater level; the weighting values were determined by using the entropy method, and the vulnerability period of groundwater resources of each sub-basin was evaluated via multiple decision-making methods. The methods developed in this study are expected to make grounds for building measures for the effective spatiotemporal management of groundwater resources.

Concrete gravity dams are widely constructed owing to their advantages of low maintenance cost and relatively low risk of sudden failure. However, the structural failure rate has been reported to be higher than other dam types. Although various studies have been conducted to assess the structural fragility of concrete gravity dams, not enough emphasis was placed on system-level fragility and sensitivity analyses, which provide crucial information for mitigating dam failure. This study proposes a new probabilistic framework for system fragility and sensitivity analysis by employing a finite element model for concrete gravity dams. The proposed framework consists of four steps, namely, structural analysis modeling considering the realistic loading conditions, component fragility analysis employing finite element reliability analysis, system fragility analysis employing system reliability analysis, and system sensitivity analysis using the finite difference method, which require several numerical algorithms and computational techniques. The proposed framework is applied to a numerical example of a typical concrete gravity dam in South Korea, and the analysis is completed successfully. As a result, the example dam is found to be relatively more vulnerable to sliding and concrete overstress than ground overstress. In addition, it is revealed that the dam system is more likely to fail in the overflow part than in the non-overflow part. The most critical factor in preventing these failures is the concrete mass density, followed by the silt mass density and the concrete compressive strength. Based on these analysis results, it is confirmed that the proposed framework provides valuable information for risk-informed structural design and failure mitigation of concrete gravity dams.

GaN thin fan were grown by spin coated colloidal GaOOH precursor. Polycrystalline GaNs with crystalline size of $10{\sim}100nm$ were grown on $SiO_2$ substrate. The shape of crystallite above $900^{\circ}C$ had the hexagonal plate and column type. X-ray diffraction patterns for them correspond to those of the hexagonal wurtzite GaN. With increasing droplets. i.e, thickness of deposited layers, XRD intensity increased. PL (photoluminescence) spectrum consisted with an weak near band-edge emission at 3.45 eV and a broad donor-acceptor emission band at 3.32 eV. From the low temperature PL measurement on GaN grown at $800^{\circ}C$ that the shallow donor-acceptor recombination induced emission was more intense than the near band-edge excitonic emission.
Values of Health Qigong as Elderly Exercise
이재범,이동준 한국발육발달학회 2015 한국발육발달학회지 Vol.23 No.1
Recently, interest in Health Qigong training in the East has been increasing and people pay more attention tothe enhancement of national health by supplementing worldly proven western medicine with traditional medicine of theirown countries. From this aspect, Health Qigong has attracted people’s attention which is a traditional exercise and healthenhancement sports in the East. Health Qigong is a traditional training method as well as exercise to coordinate and enforcevarious organs and systems of human bodies through posture coordination, breath training, relaxation of body and mind andrhythmical movements which has theoretical base in oriental medicine and does not ask extreme movements. Ageing of thepopulation makes big influence on life of individuals and families as well as causing national and social problems. In themodern society which is being changed dynamically, Health Qigong is not only a program enhancing health but also hasvalue and efficacy as a new paradigm in sports of the elderly to reach consistency between mind and body and knowledgeand conduct through training of sprit of mind, meridians, and breathing.
