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.

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.

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.

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.

In the history of Korean stone pagodas, Goryo period was the golden age and it began around the end of the 8th century and over the 9th century. At that time, the Buddhism was spread to regions out of central area with the import of the Zen buddhism in the Korean peninsula, stone pagodas which are monumental architecture of the Buddhism were also constructed in earnest all over the Korean peninsula. About 1500 of stone pagodas is numbered at present, they were developed in various ways in terms of the form and the style. However, stone pagodas out of the standard form have been thought of as non-mainstreamed ones which were in the retrogressed form, due to a monistic approach that says standard stone pagodas in Silla style are the symbol of Korean stone pagodas. "Non-mainstream" means "branches out of the mainstream" or "minority groups" in the dictionary. Therefore, various stone pagodas in minority forms and styles out of the mainstream have built the diversity of the culture of Korean stone pagodas. In result, stone pagodas constructed over Goryo period are classified to Goguryo style, Baekje style, Silla style and special ones as well as Goryo style ones which were the general forms. The special type composes of four-lion stone pagodas, blue stone pagodas, polygonal and multi-story stone pagodas, Stone brick pagodas and so on. Among the ones mentioned before, Baekje style stone pagodas and Stone brick pagodas are the most unique ones compared to stone pagodas in general type of Silla style which have a wide distribution and Goryo style stone pagodas which were built based on Silla style ones. Baekje style stone pagodas and Stone brick pagodas have, in terms of their locations, the regional bias, since the stone pagodas in one group are located in Chungchung and Julla province which were the old territory of Baekje, and the ones in the other group are distributed in Gyeongbuk area which has Gyeongju, the capital of Silla. Hence, we need to focus on the diversity and creativity in relation with the form and style of stone pagodas constructed in Korea by a study on the comparison of those two stone pagoda groups. 한국 석탑사에서 고려시대는 ‘석탑의 황금기’로, 그 태동은 8세기말~9세기경에 시작되었으며, 이들은 형식과 양식에 있어 다양한 방향으로 발전해 나갔다. 그러나 신라의 일반형 석탑이 한국 석탑의 表象이라는 일원론적 접근으로 인하여, 정형양식을 벗어난 석탑은 퇴화된 양식의 비주류로 소개되기도 하였다. ‘비주류’의 사전적 의미는 ‘중심에서 벗어난 갈래’ 또는 ‘소수파’를 의미한다. 즉, 중심에서 벗어난 다양한 소수의 석탑이 모여 한국 석탑 문화의 다양성을 형성한 것이다. 그 결과 고려시대의 석탑은 일반형인 고려식석탑을 비롯하여, 과거 삼국의 양식을 계승한 고구려, 백제, 신라양식석탑, 그리고 특수형으로 분류되는 사사자석탑, 청석탑, 다각다층석탑, 모전석탑 등이 있다. 이 중에서도 전국적으로 분포하는 신라의 일반형 석탑과 이를 토대로 성립된 고려식석탑을 기준으로 할 때, 백제양식석탑과 모전석탑은 가장 이색적인 석탑이라 할 수 있다. 하지만 건립 배경을 ‘복고적 문화현상’, 분포 환경을 ‘지역적 편재성’이라는 특징으로 주목하게 되면서, 오히려 두 석탑군의 연구 범위를 한정시킨 결과를 초래하였다. 따라서 본 논문은 건립 배경의 재검토와 조영 방식의 교류가 확인되는 사례의 비교를 통해 두 석탑군이 한국 석탑사에서 갖는 의의를 고찰하겠다.
