Though that the importance of business ethics is growing, research and education of business ethics are insufficient. There are still few to teach business ethics as a formal subject at four-year universities, and there is little research on business ethics. The education of business ethics is mainly a simple type of discussion that focuses on cases. The research of business ethics is focused on corporate social responsibility, ignoring many subjects to be dealt with in business ethics. Starting from this recognition, this paper uses qualitative research method to identify five topics to be addressed in business ethics: employee right, employee responsibility, environmental responsibility, diversity and discrimination, and international business and globalization. Directions for education and research related to each subject are from examining the latest literature related to each topic. Specifically, this paper discusses the contents to be educated in each topic, and presents directions of research to be done in the future. Consequently, this paper presents directions for the development of education and research on the five topics in business ethics. Based on this research as the theoretical basis, various researches on each subject will be possible in the future.
Conventional 3D ultrasound imaging using mechanical ID arrays suffers from poor elevation resolution due to the limited depth-of-focus (DOF). On the other hand, 3D imaging systems using 2D phased arrays have a large number of active channels and hence require a very expensive and bulky beamforming hardware. To overcome these limitations, a new real-time volumetric imaging method using curved 2-D arrays is presented, in which a small subaperture, consisting of 256 elements, moves across the array surface to scan a volume of interest. For this purpose, a 2-D curved array is designed which consists of 90$\times$46 elements with 1.5λ inter-element spacing and has the same view angles along both the lateral and elevation directions as those of a commercial mechanical 1-D array. In the proposed method, transmit and receive subapertures are constructed by cutting the four corners of a rectangular aperture to obtain a required image qualify with a small number of active channels. In addition the receive subaperture size is increased by using a sparse array scheme that uses every other elements in both directions. To suppress the grating lobes elevated due to the increase in clement spacing, fold-over array scheme is adopted in transmit, which doubles the effective size of a transmit aperture in each direction. Computer simulation results show that the proposed method can provide almost the same and greatly improved resolutions in the lateral and elevation directions, respectively compared with the conventional 3D imaging with a mechanical 1-D array.

A type IP-2 transport package should prevent a loss or dispersal of the radioactive contents and a more than $20\%$ increase in the maximum radiation level at any external surface of the package when it were subjected to the drop test under the normal conditions of transport. If a shielding thickness of IP-2 transport package is thick, a bolted lid type may prevent a loss or dispersal of the radioactive contents than the door type of ISO containers which are generally used as a type IP-2 transport package. In this paper, to evaluate the effect of drop directions on the bolt tension and the coherence of a bolt, the drop tests of preliminary small model are tested and evaluated for seven directions before the drop test of a type IP-2 transport package with a bolted lid type under the normal conditions of transport. Seven drop directions which are a bottom-vertical drop, a lid-vortical drop. a horizontal drop and four corner drops have been carried out. Using a force sensor, the bolt tension during the drop impact is measured. The coherence of bolt is evaluated by the difference between the fastening torque of bolt before a drop test and the unfastening torque of bolt after a drop impact.
This study conducted a comparative analysis of awareness level of review standards, continuing education, and awareness about the need for speciality and educational courses in order to improve quality of Korean health insurance review work and to present directions for policies of personnel development and continuing education to smoothly perform hospital's insurance claim work and Agency's review work. The analysis unit of the study is individuals, and survey was conducted among hospital's claim officers and Agency' review officers by distributing questionnaires. The major results of the study are as follows: First, it is found that hospital's claim officers and Agency's review officers have conflicting awareness about review standards; more Agency's review officers think that current review standards are universal and reasonable, while more hospital's claim officers believe that they need to be revised. Especially, hospital's claim officers replied that it is possible that review results can differ according to government's policies. Second, there is no significant difference between the two groups in the opinion that there are individual differences in awareness level of review standard. In particular, both groups share the opinion that review results can differ according to officer's interpretation of review standards. Third, Both review officer groups feel the need for further training and continuing education. Fourth, there is no difference between the two groups in the opinion that both groups members should be educated in review related educational institutions. However, while 81.5% of Agency's review officers the education should be offered at the Agency, only 45.2% of hospital's claim officers agreed to it. Fifth, both review personnel do not show any difference in awareness of needed experience to successfully perform review work; both groups replied that three to four years experience is necessary to smoothly perform claim work and review work. This study was tried in order to search for directions to improve Korean insurance review work in quality rather than to explore characteristics themselves of individual factors. In this sense, this study presupposed an intention that the educational subjects for further training and continuing education for the two groups should be the same in order to narrow the awareness gap between hospital's claim officers and Agency's review officers. Thus, this study suggests that it is desirable to offer beginner courses at junior colleges or in undergraduate courses and advanced courses in professional graduate school for six to twelve months. In that a comparison of awareness level of hospital's claim officers and Agency's review officers who are actually in practice should precede appropriate presentation of directions for the qualitative improvement of insurance review work in Korea, the significance of this study lies in comparatively analyzing the awareness level of hospital's claim officers and Agency's review officers and in presenting the establishment of future further training and continuing education.
Total Skin Electron Beam Therapy (TSEBT) of linear accelerator has become use so as to be useful, 2~9 MeV of energy territories came to be used with mycosis fungoides and cutaneous lymphomas in the superficial lesion treatment which covers the major portion of the body. I treat a patient to Stanford technique in this study, and it is $60^{\circ}$ around the patients whom Stanford technique irradiated electronic beam to a linear accelerator in horizontal directions and there is a way a standard of TSEBT treat it to six located field (anterior, posterior, and four obliques) becoming. An each field does horizontally it and consist to beam of the two component which fitted the center to a suitable angle. a patient treats it to three dual field a day in order to make short treatment time. when a first day, we treat one dual field at anterior position and two dual field at posterior position. when the second day, treat one dual field at posterior position and two dual field at anterior position. Therefore, six dual field is finished in perfect periodic two days. we made cylindrical acrylic phantom, and I inserted a dosimeter film between phantom. in order to measure a dose distribution calculation before treat a patient, and a patient checked it in six field directions that got from a treatment. It is after that thermoluminescent dosimetry (TLD) as it uses Rando phantom and then measurement dose distribution in six field directions after attaching at chest, the right and left flank, a back after irradiation.
Since 1990's, the Korean society, experiencing the low fertility and aging society, has been confronting with the threats in health care sector. The threats are the increases in the demand for health care, health care financial burden, and so on. In particular, the change of disease pattern and aging population result in the increases patients' demand for not only western medical services but also oriental medical services and complimentary medicine. Recently, the increases in availability of oriental medical services and the health care resources related to oriental medicine are raising some issues and conflicts in the Korean health sector. Theses circumstance required policy makers, central and local government, and public health sector to develop health policies related to oriental medicine and interface or integrate of traditional Korean medicine and Western medicine. For the near future, these issues will probably remain the focus of integration of traditional Korean medicine and Western medicine in public health sector. To cope with the threats in health care sector, one of the opportunities is to scale-up e public role of traditional Korean medical services. The main purpose of this study was to develop strategies to scale-up the Public role of traditional Korean medical services for the future society. The research questions are: what are the trends and problems in traditional Koran medical sector; what are the causes of or associated factors to the problems; how to cope with the problems and how to resolve the cause?; what are the health policy directions and its strategies that the government should take to cope with the future demand and the burden on health care sector? The results of this study are as follows. In order ta scale-up the public role of traditional medicine, this research offered health policy directions for traditional Korean medicine in response to a change environment of health care sector. There are four directions to be addressed: 1) the development of and investment in public oriental medicine infra-structure; 2) the development of public policy on oriental medicine; 3) modernization and globalisation of traditional Korean medicine; 4) the expansion of academic exchange between Western medicine and traditional Korean medicine. Finally, we discussed stakenholders' on traditional Korean medicine in the health care market. Then, public policy options for future society was suggested.
This is the second of two papers on the 3D numerical modeling of nearshore hydro- and morphodynamics. In Part I, the focus was on surf and swash zone hydrodynamics in the cross-shore and longshore directions. Here, we consider nearshore processes with an emphasis on the effects of oceanic forcing and beach characteristics on sediment transport in the cross- and longshore directions, as well as on foreshore bathymetry changes. The Delft3D and XBeach models were used with four turbulence closures (viz., ${\kappa}-{\varepsilon}$, ${\kappa}-L$, ATM and H-LES) to solve the 3D Navier-Stokes equations for incompressible flow as well as the beach morphology. The sediment transport module simulates both bed load and suspended load transport of non-cohesive sediments. Twenty sets of numerical experiments combining nine control parameters under a range of bed characteristics and incident wave and tidal conditions were simulated. For each case, the general morphological response in shore-normal and shore-parallel directions was presented. Numerical results showed that the ${\kappa}-{\varepsilon}$ and H-LES closure models yield similar results that are in better agreement with existing morphodynamic observations than the results of the other turbulence models. The simulations showed that wave forcing drives a sediment circulation pattern that results in bar and berm formation. However, together with wave forcing, tides modulate the predicted nearshore sediment dynamics. The combination of tides and wave action has a notable effect on longshore suspended sediment transport fluxes, relative to wave action alone. The model's ability to predict sediment transport under propagation of obliquely incident wave conditions underscores its potential for understanding the evolution of beach morphology at field scale. For example, the results of the model confirmed that the wave characteristics have a considerable effect on the cumulative erosion/deposition, cross-shore distribution of longshore sediment transport and transport rate across and along the beach face. In addition, for the same type of oceanic forcing, the beach morphology exhibits different erosive characteristics depending on grain size (e.g., foreshore profile evolution is erosive or accretive on fine or coarse sand beaches, respectively). Decreasing wave height increases the proportion of onshore to offshore fluxes, almost reaching a neutral net balance. The sediment movement increases with wave height, which is the dominant factor controlling the beach face shape.

This study aimed to investigate the effect of changes in pressure levels and gaze directions on deep neck flexor muscle thickness. Twenty-seven subjects participated in this study. Ultrasound imaging of the longus colli (LC) and sternocleidomastoid (SCM) were measured in four gaze directions (0°, 20°, 40°, 60°) and five pressure levels (20 mmHg, 22 mmHg, 24 mmHg, 26 mmHg, 28 mmHg) during cranial-cervical flexor (CCF) exercises. Repeated ANOVA was performed for analysis of muscle thickness difference according to gaze direction and pressure levels in LC and SCM. Results: LC showed a significant difference between 0° and 20°, 0° and 40°, and 0° and 60° at pressures of 20 mmHg and 22 mmHg (p<.05). SCM displayed a significant difference between 0° and 20°, 20° and 40°, and 40° and 60° at 28 mmHg (p<.05). In this study, it was found that setting the gaze direction to 20° for the CCF exercise can increase the activation of LC and lower the activity of SCM to obtain the effect of exercise. Based on the results of this study, it is hoped that the beneficial effects of the CCF exercise can be increased by setting an optimal gaze direction in a clinical environment.
Based on the premise that perspectives or the frame of cognition may affect the ways that family practitioners support or intervene in families, this study aimed to investigate the perspectives of Certified Healthy Family Specialists (CHFS) on family practice in the Healthy Family Support Centers. A total of 9 CHFSs gave information about their beliefs and perspectives on family practice in in-depth interview. Additionally, 5 CHFS participated in focus group interview and gave information about their values, beliefs, and perspectives on family practice. Through qualitative analyses, four perspectives were found to be explicitly or implicitly carried by CHFSs: System theory perspective, Strengths perspective, Family cognition perspective, and Public intervention perspective. These four perspectives are currently leading themes of family research and are prospected to prevail in family support and intervention practices in the Healthy Family Support Centers in South Korea. Based on the results of qualitative analyses, directions and range of influence in perspectives on family practice perceived by CFHSs were discussed. In this study, the subject of Healthy Family Project, the CHFSs' aims, and emphasis on family practice were dealt with, and developmental direction establishment related to the Healthy Family Support Centers and CFHSs in the dimension of practice and policy in the future were implied.
The Korea Astronomy and Space Science Institute (KASI) has been developing a next-generation coronagraph (NGC) in cooperation with NASA to measure the coronal electron density, temperature, and speed simultaneously, using four different optical filters around 400 nm. KASI organized an expedition to demonstrate the coronagraph measurement scheme and the instrumental technology during the 2017 total solar eclipse (TSE) across the USA. The observation site was in Jackson Hole, Wyoming, USA. We built an eclipse observation system, the Diagnostic Coronal Experiment (DICE), composed of two identical telescopes to improve the signal-to-noise ratio. The observation was conducted at four wavelengths and three linear polarization directions in the limited total eclipse time of about 140 seconds. We successfully obtained polarization data for the corona but we were not able to obtain information on the coronal electron temperature and speed due to the low signal-to-noise ratio of the optical system and strong emission from prominences located at the western limb. In this study, we report the development of DICE and the observation results from the eclipse expedition. TSE observation and analysis with our self-developed instrument showed that a coronagraph needs to be designed carefully to achieve its scientific purpose. We gained valuable experience for future follow-up NASA-KASI joint missions: the Balloon-borne Investigation of the Temperature and Speed of Electrons in the Corona (BITSE) and the COronal Diagnostic EXperiment (CODEX).
