Unlike in the past, standards for the quantity and quality of work expected from medical school faculty are continuously rising, causing changes and stress in various areas. This highlights the need for career development among medical school faculty for professional, personal, organizational, and societal reasons. The role of medical school faculty has become more diverse, leading to an increase in the types and levels of competencies required. Medical schools must support their faculty members with diverse identities in fully utilizing their capabilities to achieve the institution's mission. Furthermore, societal changes suggest that career development for medical school faculty will become even more crucial in the future. To achieve this, both individuals and organizations must make efforts and play appropriate roles. For this purpose, medical schools use a combination of promotion and tenure evaluations and faculty development programs, while individual faculty members follow a career path within the medical school environment. Medical school faculty must be able to meet the evolving demands at each stage of their careers. It is important for professors, who engage in career development, to have a clear sense of their identity and values, and to prioritize their career goals. Medical schools should also ensure that the implicit messages they convey align with the organization's explicit values. Finally, proactively preparing for future changes in society and generations is essential from a long-term perspective.

Vertigo and dizziness are common symptoms with various etiologies and pathogeneses. Vertigo is an illusion of motion due to disease of the vestibular system, usually a sense of rotation. Dizziness, a term that represents a wide range of non-vertigo symptoms, is commonly associated with non-vestibular disorders including old age, cardiac syncope, orthostatic hypotension, metabolic disease, anxiety, and drugs. Vertigo should be determined whether the cause is central or peripheral. Peripheral vertigo is usually benign but central vertigo is serious and often require urgent treatment. The careful history and detailed physical examinations(pattern of nystagmus, ocular tilt reaction, head impulse test and positional tests such as Dix-Hallpike maneuver) provide important clues to the diagnosis of vertigo. Most of patients have benign peripheral vestibular disorders - vestibular neuritis, benign paroxysmal positional vertigo (BPPV), and Meniere's disease. BPPV is a leading cause of peripheral vertigo and can easily be cured with a canalith repositioning maneuver. In this review, a focus is on the differential diagnosis of common vestibular disorders with peripheral and central causes.

Community has been defined as a group of interacting people living in a common location. The word is often used to refer to a group that is organized around common values and is attributed with social cohesion within a shared geographical location, generally in social units larger than a household. The word can also refer to the national community or global community. The word "community" is derived from the Old French communit$\acute{e}$ which is derived from the Latin communitas (cum, "with/together" + munus, "gift"), a broad term for fellowship or organized society. A sense of community refers to people's perception of interconnection and interdependence, shared responsibility, and common goals. Understanding a community entails having knowledge of community needs and resources, having respect for community members, and involving key community members in programs. But, on account of industrial development, At some point, we have individualism behavior. therefore, This study will achieve local community activation using school land.

The gridless (or meshfree) methods, such as MPS, SPH, FPM an so forth, are feasible and robust for the problems with moving boundary and/or complicated boundary shapes, because these methods do not need to generate a grid system. In this study, a gridless solver, which is based on the combination of moving least square interpolations on a cloud of points with point collocation for evaluating the derivatives of governing equations, is presented for two-dimensional unsteady incompressible Navier-Stokes problem in the low Reynolds number. A MAC-type algorithm was adopted and the Poission equation for the pressure was solved by successively in the moving least square sense. Some weighing functions were tested in order to investigate the up-winding effect for the convection term. Some typical problems were solved by the presented solver for the validation and the results obtained were compared with analytic solutions and the numerical results by conventional CFD methods, such as FVM.

Monitor of All-sky X-ray Image (MAXI) is a Japanese X-ray all-sky surveyer mounted on the International Space Station (ISS). It has been scanning the whole sky since 2009 during every 92-minute ISS rotation. X-ray transients are quickly found by the real-time nova-search program. As a result, MAXI has issued 133 Astronomer's Telegrams and 44 Gamma-ray burst Coordinated Networks so far. MAXI has discovered six new black holes (BH) in 4.5 years. Long-term behaviors of the MAXI BHs can be classified into two types by their outbursts; a fast-rise exponential-decay type and a fast-rise flat-top one. The slit camera is suitable for accumulating data over a long time. MAXI issued a 37-month catalog containing 500 sources above a ~0.6 mCrab detection limit at 4-10 keV in the region ${\mid}{b}{\mid}$ > $10^{\circ}$. The SSC instrument utilizing an X-ray CCD has detected diffuse soft X-rays extending over a large solid angle, such as the Cygnus super bubble. MAXI/SSC has also detcted a Ne emission line from the rapid soft X-ray nova MAXI J0158-744. The overall shapes of outbursts in Be X-ray binaries (BeXRB) are precisely observed with MAXI/GSC. BeXRB have two kinds of outbursts, a normal outburst and a giant one. The peak dates of the subsequent giant outbursts of A0535+26 repeated with a different period than the orbital one. The Be stellar disk is considered to either have a precession motion or a distorted shape. The long-term behaviors of low-mass X-ray binaries (LMXB) containing weakly magnetized neutron stars are investigated. Transient LMXBs (Aql X-1 and 4U 1608-52) repeated outbursts every 200-1000 days, which is understood by the limit-cycle of hydrogen ionization states in the outer accretion disk. A third state (very dim state) in Aql X-1 and 4U 1608-52 was interpreted as the propeller effect in the unified picture of LMXB. Cir X-1 is a peculiar source in the sense that its long-term behavior is not like typical LMXBs. The luminosity sometimes decreases suddenly at periastron. It might be explained by the stripping of the outer accretion disk by a clumpy stellar wind. MAXI observed 64 large flares from 22 active stars (RS CVns, dMe stars, Argol types, young stellar objects) over 4 years. The total energies are $10^{34}-10^{36}$ erg $s^{-1}$. Since MAXI can measure the spectrum (temperature and emission measure), we can estimate the size of the plasma and the magnetic fields. The size sometimes exceeds the size of the star. The magnetic field is in the range of 10-100 gauss, which is a typical value for solar flares.

본 논문에서는 하이데거의 '현존재(Da-Sein)'로서 인간관이 학교교육목표 설정에 주는 함의를 탐구하였다. 서구의 전통적 인간관은 이성적 인간관이다. 흄은 이미 자신의 독특한 인간관인 정념론을 통해 이성적 인간관을 비판하였다. 그러나 흄의 정서적 인간관은 이성적 인간관과 마찬가지로 기능적 인간관의 한계를 벗어나지 못했다. 반면, 하이데거는 실존적 인간론을 통해 기능적 인간관을 극복하고자 하였으며, '현존재'라는 새로운 개념을 제시하였다. '현존재'는 인간이라는 용어에 담긴 '이성적 동물'이라는 선입견을 해체하고자 하이데거가 창조한 인간을 대체한 용어이다. '현존재'는 실존성, 각자성, '세계-내-존재'라는 세 가지 성격을 갖는다. '현존재'의 세 가지 성격은 다음과 같이 학교교육목표 설정에 시사점을 준다. 첫째, 학교교육목표는 학생들이 자아를 지속적으로 발견해 나갈 수 있는 의미를 가진 용어로 진술되어야 한다. 둘째, 학교교육목표는 학생들이 다양한 방식으로 구현할 수 있어야 한다. 셋째, 학교교육목표는 학생들이 공유할 수 있는 보편성을 내재해야 한다. 현재 일부 학교에서 이루어지는 학생의 행복을 중심에 두고 고려된 학교교육목표의 변화는 '현존재'의 의미와 관련된 측면이 있다. 하이데거의 '현존재'에 기반한 학교교육목표의 설정은 인간의 진정한 존재 특성을 고려하는 교육으로의 지평을 열어줄 것이다.

The U.S. response to increased international competition was examined in the present study in order to have more comprehensive understanding of the U.S. textile and clothing market. The method employed to conduct the study was the analysis of the written materials, interview with professionals, and the survey of the actual situations of the U.S. textile and apparel industries. The results are summarized as follows; 1. Official U.S. textile and apparel trade policy has been quite has been quite protective since 1950's. The protective trend has been embodied in Japan Cotton Textile Export Control (reciprocal trade agreement signed by the U.S. and Japan in 1957), Short Term Arrangement Regarding International Trade in Cotton Textiles, Long Term Cotton Textile Arrangement (1962∼1973), and Multi-fiber Arrangement (1974∼). Other governmental programs designed to improve the competitiveness of the U.S. textile and apparel industries include Long-term Textile and Apparel Products Export-expansion Program, and 807 Trade to take labor cost advantage. 2. Along with the quite protective governmental trade policy, the corporate responses have been made such as new sourcing mixes, investment in technology, specialization in the textile and apparel industries, and recent strategies pursued by retailer's. The apparel industry was subject to pressure from imports that increased at moderate levels, and the U.S. textile and apparel industries have made extensive efforts to adjust to the increasing competition from abroad. The textile and apparel industries have taken steps to increase labor productivity through automation, to speed management to create and introduce new products and new methods, and have lowered indirect overhead costs. Several industrywide promotion campaigns have attempted to establish a greater public awareness of international competition and to develop a preference for apparel produced in the United States. 3. Regarding these response of the U.S. and other situations of world textile and apparel trade market, much of the sense of crisis that pervades Korean textile and apparel industries has to do with the problem of adjusting government and corporate policy. Textile and apparel industry of Korea faces on going pressure to reduce costs, improve quality, increase service, develop new markets, diversify, and differentiate itself from its foreign competitors. The strategies that have been adopted in the past have generally worked in the past, but the time has come to adopt strategies that reflect present conditions. If this is not done, then we stand to lose large segments of these industries, which once lost will not easily be regenerated.
