Purpose: This study explores how demographic transitions with workforce implications taking place in South Korea are affecting the job market, and proposes a novel conceptual model to analyze the increased role that migrant workers will play as the changes progress in the medium term. Research design, data and methodology: A qualitative approach based on the available published data is used in order to create a conceptual model that could be used to determine the order in which job sector strata will be gradually taken over by migrant workers, as the demographic transitions will create an increasing need for workforce reforms. Results: The study determines that migrant workers will replace domestic Korean workers in a stratified manner, initially in rural areas, followed by regional cities and then in the industrial areas on the edges of big cities, and the strata can be analyzed based on a proposed four-category model to determine where the opportunities will open. Conclusion: It is possible to use a conceptual model for this phenomenon. Extensive Government planning is needed to avoid possible social exclusion problems and to determine how to keep the economies of rural and regional Korean cities economically viable while they are becoming increasingly depopulated.

Structural walls have been mostly used for the design of reinforced concrete buildings in seismic areas because they play a role as an efficient bracing system and offer great potential for lateral load resistance and drift control. The lateral resistance system for the earthquake load should be designed to have enough ductility and stable hysteretic response in the critical regions where plastic deformation occurred beyond yielding. The behavior of the reinforced concrete element to experience large deformation in the critical areas by a major earthquake is affected by the performance of the confined core concrete. Thus, the confinement of concrete by suitable arrangements of transverse reinforcement results in a significant increase in both the strength and ductility of compressed concrete. This paper reports the experimental results of reinforced concrete structural walls for wall-type apartment structure under axial loads and cyclic reversal of lateral loads with different confinement of the boundary elements. The results show that confinement of the boundary element by open 'U'-bar and cross tie is effective. The shear strength capacity is not increased by the confinement but deformation capacity is improve.

During the past decade or so in Korea, 119 relief squad members were supposed to respord first urgent or emergency cases. The primary purpose of this study was to assess what levels of knowledge and techniques in prehospital care the 119 relief squad members showed. Data regarding the knowledge and technique levels were collected from both the 119 relief squad members (n=63) and the emergency room nurses(n=46). The Results indicated that the 119 relief squad when compared to emergency nurses, showed higher scores for knowledge and techniques in some areas of prehospital care but not in other areas, However, no differences in knowledge and technique were found when the ANOVAs were calculated with two covariates : duration of their career in emergency medical services and frequency of their exposure to lectures on emergency medical technology. In addition, many respondents in the 119 relief squad group rated themselves poorly in knowledge and techniques of prehospital care, The findings imply that qualitatively better curricula should be given to the 119 relief squad members before they are allowed to play an important role in the emergency medical service system. These findings are also discussed in the context of improving the emergency medical service system.

Background: In a previous study undertaken to quantify capsular volume in rotator cuff interval or axillary pouch, significant differences were found between controls and patients with instability. However, the results obtained were derived from two-dimensional cross sectional areas. In our study, we sought correlation between three-dimensional (3D) capsular volumes, as measured by magnetic resonance arthrography (MRA), and multidirectional instability (MDI) of the shoulder. Methods: The MRAs of 21 patients with MDI of the shoulder and 16 control cases with no instability were retrospectively reviewed. Capsular areas determined by MRA were translated into 3D volumes using 3D software Mimics ver. 16 (Materilise, Leuven, Belgium), and glenoid surface area was measured in axial and coronal MRA views. Then, the ratio between capsular volume and glenoid surface area was calculated, and evaluated with control group. Results: The ratio between 3D capsular volume and glenoid surface area was significantly increased in the MDI group ($3.59{\pm}0.83cm^3/cm^2$) compared to the control group ($2.53{\pm}0.62cm^3/cm^2$) (p<0.01). Conclusions: From these results, we could support that capsular volume enlargement play an important role in MDI of the shoulder using volume measurement.

We report on the fabrication and characterization of self- and artificially-controlled ZnO nanostructures have been investigated to establish nanostructure blocks for ZnO-based nanoscale device application. Systematic realization of self- and artificially-controlled ZnO nanostructures on $SiO_2/Si$ substrates was proposed and successfully demonstrated utilizing metalorganic chemical vapor deposition (MOCVD) in addition with a focused ion beam (FIB) technique. Widely well-aligned two-dimensional ZnO nanodot arrays ($4{\sim}10^4$ nanodots of 130-nm diameter and 9-nm height over $150{\sim}150{\mu}m^2$ with a period of 750 nm) have been realized by MOCVD on $SiO_2/Si$ substrates patterned by FIB. A low-magnification FIB nanopatterning mode allowed the periodical nanopatterning of the substrates over a large area in a short processing time. Ga atoms incorporated into the surface areas of FIB-patterned nanoholes during FIB engraving were found to play an important role in the artificial control of ZnO, resulting in the production of ZnO nanodot arrays on the FIB-nanopatterned areas. The nanodots evolved into dot clusters and rods with increasing MOCVD growth time.

Plagiorchis muris has been found in both been found in both house and field rats as well as in humans. The infection status of th second intermediate hosts of P.muris is prerequisite in understanding their biological features in an ecosystem. Six species of dragonflies were caught in a wide range of areas in Korea;and they were Sympertrum darwinianum, S.eroticum, S. pedomontanum, S. infuscatum, Pantala flavoscens, Caloteryx atrata, and Othertrum albistylum speciosum. The occurrence of P. muris metacercariae in dragonflies was nationwide with various infection rates. The metacercarial burden of P. muris in the surveyed areas was the highest in S. eroticum followed by S. darwinianum, S. pedomontanum, and C. atrata. The highest infection rate by P. muris metacercariae was found in S. darwinianum followed by S. eroticum. The metacercarial buredn was particularly heavy in the dragonflies found in Hamyang-gun and Kosong-gun, Kyongsangnam-do. It is, therefore, likely that dragonflies play a significant role as the second intermediate hose in the life cycle of P. muris in Korea.

강관은 Northridge 지진이 발생했을 당시 산사태가 일어나는 언덕이나 산악지역에 매설되어 있었다. 본 논문은 지리정보체계(GIS) 시스템에서 위치에 따라 강관을 서로 다른 유형별로 분류하고 정의하였다. 이 논문은 지반속도와 강관의 손상관계를 분석하고 Northridge 지진 시 발생한 산사태의 영향을 받았던 지역을 조사하였다. 하나의 주목할 만한 사실은 Northridge 지진 후 강관의 손상률이 다른 종류의 매설관, 특히 캐스트아이런(CI)보다 더 높았다는 것이다. Northridge 지진으로 인한 상대적으로 높은 강관의 손상률은 가장 큰 내부압력을 요하는 곳에서의 설치관례와 부식으로 인한 영향으로 해석될 수 있다.

This study analyzes time variability of the normalized difference vegetation index (NDVI), the leaf area index (LAI) and surface temperature (Ts) estimated from AVHRR data collected from across the Korean peninsula from 1981 to 1994. In the present study, LAI defined as vegetation density, as a function of NDVI applied for the vegetation types and Ts defined by the split-window formulation of Becker and Li (1990) with emissivity of a function of NDVI, are used. Results of the inter-annual, intra-annual and intra-seasonal variabilities in Korea show: (1) Inter-annual variability of NDVI is generally larger in the southem and eastern parts of the peninsula than in the western part. This large variability results from the significant mean variation. (2) Inter-annual variability of Ts is larger in the areas of smaller NDVI. This result shows that the NDVI play a small role in emissivity. (3) Inter-annual variability of LAI is larger in the regions of higher elevation and urban areas. Changes in LAI are unlikely to be associated with NDVI changes. (4) Changes in NDVI and Ts are likely dominant in July and are relatively small in spring and fall. (5) Urban effect would be obvious on the time-varying properties of NDVI and Ts in Seoul and the northern part of Taejon, where NDVI decreases and Ts increases with a significant magnitude.

근래 자살예방에 대한 관심이 증가되면서 이에 대한 실질적인 전략들이 많이 개발되었다. 특히 서구에서는 지역사회 정신건강 기관에서 자살예방을 위한 치료 프로그램이 특성화되어 운영되는 것은 물론, 대학 및 병원과 연계하여 자살 충동의 원인이 되는 다양한 정신 병리적 혹은 사회 심리적인 원인들을 규명하고 이에 대한 계속적인 연구가 시행되고 있다. 본 연구에서는 음악치료가 자살의 중요한 요인인 우울에 미치는 영향을 중심으로 하여 자살예방을 위한 음악치료적인 접근을 제시하고자 하였다. 접근방법으로는 노래심리치료(Song Psychotherapy), MI(Music Imagery), 역할악기즉흥연주(Role Play Instrumental Improvisation)심리치료를 주요방법으로 구성한 음악심리치료 프로그램이 제공되었다. 연구대상은 우울을 동반한 정신적 외상상태로 자살을 시도했던 30대 여성이었으며 치료기간은 주 1회 90~120분의 7회의 세션이 실시되었다. 음악치료 전개에 따라 우울척도와 자살생각척도를 통해 변화를 양적 질적으로 연구 방법들을 사용하였다. 연구 결과 내담자는 음악심리치료를 통해 안정감과 편안함을 느끼고 방어나 저항 없이 자신의 감정의 생각, 그리고 내면의 세계를 탐구할 수 있었다. 이 경험들을 통하여 내담자는 자아개념과 새로운 가치를 발견하게 되고 부정적인 정서가 긍정적인 정서로 바뀌게 됨에 따라 우울감이 감소되었다. 또한 자살에 대한 생각보다는 현재 삶에 대한 구체적인 계획을 행동으로 옮기게 되었다. 특히 역할악기 즉흥연주 과정의 음악은 기분의 변화, 타인과의 관계변화, 태도의 변화 등 다양한 영역변화를 가져오는 주체로서 '치료' 그 자체로 사용되어졌다. 그리고 음악은 해결되지 않은 정신적 외상상태에 있었던 내담자의 심리적 위축과 긴장감, 무기력한 에너지 등을 표출시키고 본능과 감정을 그대로 경험할 수 있도록 하였다. 더 나아가 '거짓자아'와 분리되어 '참 자아'와의 통합을 이루어가도록 도움을 주었다. 결과적으로 음악심리치료는 우울을 감소시키고 자살충동 예방에 효과적으로 적용될 수 있음을 시사하고 있다.
