Applying the numerical scheme developed by Semtner (1974), we investigate the circulation system in the Japan Sea in response to the air-sea interaction and the wind. In spite of blocking straits, resulting surface circulation pattern is similar to the schematic surface current chart introduced by Uda(1934) and Naganuma (1972); the northward flow along the Korean coast and the anticlockwise gyre in the northeastern part of the Japan Sea. Also the southward current flows along the Korean coast at depth of 100-200 m as similar to the North Korean Cold Current suggested by Kim and Kim (1983). And the sinking phenomenon of relatively saline water in the northeastern part of the Japan Sea is similar to the formation of the Japan Sea Proper Water.

코로나 19사태로 인한 ‘사회적 거리두기’ 운동이 지속되면서 사람들의 생활 형태가 변화된 양상을 띈다. 특히 모임 활동 및 단체 활동의 제한으로 개인 시간이 이전에 비해 증대되었다. 홀로 자택에 머무르는 시간의 증가로 인해 사회적 단절감과 고립감이 심화되며 “코로나 블루”로 일컫어지는 신종 정신질환이 많은 사람들에게 생겨나 사회적 문제로 이슈화 되고 있다. 본 논문에서는 이러한 사회적 문제를 완화시키기 위해 고안된 새로운 디퓨저 개발과정 및 기존 디퓨저에서 볼 수 없었던 IoT기술과 조향기술과의 접목을 통한 차별성에 대해 서술하였다.

Numerous fabrication techniques have been used to mimic cylindrical natural tissues, such as blood vessels, tendons, ligaments, and skeletal muscles. However, most processes have limitations in achieving the biomimetic properties of multilayered and porous architectures. In this study, to embrace both features, a novel self-assembly method was proposed using electrospun microfibrous sheets. A bilayer microfibrous structure, comprising two sheets with different internal stresses, was fabricated by electrospinning a polycaprolactone (PCL) sheet on a uniaxially stretched thermoplastic polyurethane (TPU) sheet. Then, by removing the stretching tension, the sheet was rolled into a hollow cylindrical structure with a specific internal diameter. The internal diameter could be quantitatively controlled by adjusting the thickness of the PCL sheet against that of the TPU sheet. Through this self-assembly method, biomimetic cylindrical structures with multilayer and porous features can be manufactured in a stable and controllable manner. Therefore, the resulting structures may be applied to various tissue engineering scaffolds, especially vascular and connective tissues.

최근 현대인에게는 질좋은 숙면이 필수적이다. 건강한 숙면을 위해서는 편안한 수면환경이 중요하므로 IoT베개와 매트는 개개인에게 맞는 수면 자세를 잡아 효율적으로 현대인들의 수면의 질을 높여줄 것이다. IoT의 베개의 센서가 머리의 움직임과 방향을 실시간으로 모니터링하여 설치된 장치가 자세를 바로잡아주고 장치와 연동된 앱을 통하여 수면의 종류와 패턴, 수면 시간을 상세분석하는 체계적인 맞춤형 수면 관리를 통해 수면 건강정보를 제공할 것이다. 또한, 수면 건강정보를 서버에서 종합하여 각 가정의 환자의 상태를 모니터링하여 원격진료가 가능하다.

In this paper, we analyze English speaking evaluation from various angles without human evaluation intervention and develop tools to evaluate it according to educators educational direction through quantitative indicators. The Whisper model was used as a STT (Speech to Text) model, and character characteristics and speech characteristics are extracted using the STT model, and English speaking ability is evaluated using the corresponding indicators. Through quantitative evaluation indicators, the relative importance of evaluation indicators is adjusted according to the instructors direction and goals and used to conduct a comprehensive evaluation.

The Purpose of this study was to identify reasons behind the high turnover rate of nurses, and to delineate measures for inactive nurses to participate in professional nursing activities so as to upgrade the quality of the health care delivery system in Korea, Thus, tried this study to drive market entry of these idleness manpower. Methods: This study used the action research, to collect idea from hospital/nurse administrators, nurses on the job, part-time nurses. Results: This study basic data about flexible shift form through scientific paper, Internet, individual contact source collection do, and compare each situation by direct conversation with a nurse, director of a hospital, nursing administrators about flexible shift form, and analyze example of hospital which utilize flexible shift form actually or utilized and deduced advantage, shortcoming, cause of failure, cause of success, other application plan. Conclusions:1. Emphasize that database about idleness manpower should be put priority certainly. 2. In case of idleness manpower wants a re-employment hospital and institution which can connect to administer demonstration premise. 3. Emphasize that need organ to enforce education program and this that idleness manpower can apply in nursing spot. 4. Premise nurse`s great people image and research about method that convert productivity of nursing to money.
