Objectives : A transition course of 'Introduction to Clinical Korean Medicine' was developed to meet the demands for better preparation for clinical application of Korean Medicine within the curriculum. A Korean Medical Classics curriculum reflecting such demands was newly designed. Methods : Based on the 'Introduction to Clinical Medicine(ICM)' course of the Medical School curriculum that follows the medical education guideline, the 'Introduction to Clinical Korean Medicine(ICKM)' course was designed and developed. The role of Korean Medical Classics was suggested in the process. Results : In the following course, Korean Medical diagnosis, diagnostics, patient intake methods reflecting the Korean Medical diagnostic system, clinical skills, basic skills, treatment planning, patient education, etc. are included. Faculty members of the basic sectors of the Korean Medical school will participate in this curriculum, of which a head will be appointed to overlook the curriculum. In the case of Korean Medical Classics, previous learning outcomes need to be reorganized based on clinical expression while clinical case studies need to be added to course material. A more active approach utilizing new pedagogic strategies and teaching methods should be taken. Conclusions : The Korean Medical Classics curriculum could effectively take on the introductory role to clinical Korean Medicine, successfully strengthening the connection between the basic and clinical Korean Medicine to improve learners' satisfaction.

Unlike in the past, successful global companies are striving to create a horizontal organizational structure and autonomous corporate culture by empowering their members with autonomy and responsibility. The purpose of this study is to conduct an empirical analysis on the effect of job stress and managerial coaching behavior on the effect of psychological empowerment on organizational commitment and turnover intention. Negative situational factors (job stress) and positive situational factors (managerial coaching behavior) were considered and presented at the same time, and their effectiveness was verified. As a result of the analysis, it was found that psychological empowerment had a positive effect on organizational commitment, but did not to affect turnover intention. Also, it was found that job stress and managerial coaching behavior had a mediating effect. The results of this study can be used as a effective guideline on creating an autonomous organizational climate and creating a successful corporate culture through this.

T-shaped column is usually used as side column in buildings, which is one of the weak members in structural system. This paper presented a quasi-static cyclic loading experiment of six specimens of reinforced concrete (RC) T-shaped columns under compression-flexure-shear-torsion combined loadings to investigate the effect in the ratio of torsion to moment (T/M) and axial compression ratio (n) and height-thickness ratio of flange plate (φ) on their seismic performance. Based on the test results, the failure characteristics, hysteretic curves, ductility, energy dissipation, stiffness degradation and strength degradation were analyzed. The results show that the failure characteristics of RC T-shaped columns mainly depend on the ratio of torsion to moment, which can be divided into bending failure, bending-torsion failure and shear-torsion failure. With the increase of T/M ratio, the torsion ductility coefficient increased, and in a suitable range, the torsion and horizontal displacement ductility coefficient of RC T-shaped columns could be effectively improved with the increase of axial compression ratio and the decrease of height-thickness ratio of flange plate. Besides, the energy dissipation capacity of the specimens mainly depended on the bending and shear energy dissipation capacity. On the other hand, the increase of axial compression ratio and the ratio of torsion to moment could accelerate the torsional and bending stiffness degradation of RC T-shaped columns. Moreover, the degradation coefficient of torsion strength was between 0.80 and 0.98, and that of bending strength was between 0.75 and 1.00.

The export regulation of semiconductor core materials, which began with the recent revision of the export management regulations of Japan, raises the need for a new cooperation network. A hierarchical management network that was effective in the fast-follower system requires organic cooperation between the public sector and industry through a multilateral network that emphasizes horizontal co-operation among innovation actors. This study focused on the relational capital that exists among members of a business association such as an association that has been relatively marginalized from previous studies. In addition, this study aimed to analyze the effect of network activity characteristics such as industry-university linkage and informal exchange on technological innovation. Through this, I would like to draw implications for enhancing the effectiveness of the government's R & D support and innovation performance of R & D companies. Based on the results of the SMEs R & D survey, this study found that relational capital, informal exchange had a positive effect on technological innovation performance. However, if the relational capital exceeds a certain level, it is analyzed that there is a negative effect due to group think and lock-in effect. This means that informal exchange channels should be expanded for innovation and enhancement, and relational capital should be managed in consideration of the negative effects that may occur when certain levels are exceeded.

We have analyzed 42 research papers regarding on the solar astronomy written by North Korea scientists to investigate the current status of astronomical activities in North Korea. The papers are surveyed from the 'Bulletin of Astronomy', the 'Physics', the 'Bulletin of Academy of Science', and the 'Natural Science' in North Korea, and SCI journals. In addition, we refer to the presentation material announced in the 2015 IAU by director of Pyongyang Astronomical Observatory (PAO) and the 2013 OAD/IAU reports. We have analyzed the papers statistically according to three criteria such as research subject, research field, and research members. The main research subjects are the sunspot (28%), observation system (21%), and space environments (19%). The research fields are distributed with data analysis (50%), numerical method (29%), and instrument development (21%). There have been 25 and 9 researchers in the solar astronomy and space environment, respectively since 1995. North Korea's solar research activities were also investigated in three area: instrument, solar physics, and international research linkage. PAO has operated two of sunspot telescope and solar horizontal telescope for spectroscopy and polarimetry, but there is no specific information on solar radio telescopes. North Korea has cooperated in solar research with Europe and China. We expect that the results of this study will be used as useful resource in supporting astronomical cooperation between South and North Korea in the future.

In this study, we applied an on-site diagnostic method for estimating the structural safety of a plastic greenhouse. A three-dimensional light detection and ranging (3D LiDAR) sensor was used to scan the greenhouse to extract point cloud data (PCD). Differential thresholds of the color index were applied to the partitions of raw PCD to separate steel frames from plastic films. Additionally, the K-means algorithm was used to convert the steel frame PCD into the nodes of unit members. These nodes were subsequently transformed into structural shape data. To verify greenhouse shape reproducibility, the member lengths of the scan and blueprint models were compared with the measurements along the X-, Y-, and Z-axes. The error of the scan model was accurate at 2%-3%, whereas the error of the blueprint model was 5.4%. At a maximum snow depth of 0.5 m, the scan model revealed asymmetric horizontal deflection and extreme bending stress, which indicated that even minor shape irregularities could result in critical failures in extreme weather. The safety factor for bending stress in the scan model was 18.7% lower than that in the blueprint model. This phenomenon indicated that precise shape estimation is crucial for safety diagnostic. Future studies should focus on the development of an automated process based on supervised learning to ensure the widespread adoption of greenhouse safety diagnostics.

Recently, foundations of heavy structures such as bridge abutments have been built on slopes or near the crest of slopes at an increasing rate. Because the bearing capacity of such foundations is considerably lower than the bearing capacity of the same soil on a level ground, deep footings such as piles and caissons are often used. However, the costs of such methods are generally very high. One of the new techniques to overcome the problem is to place reinforcing members such as geosynthetics or metal strips horizontally at some depths beneath the footings. Rational methods of analysis to predict the bearing capacity of footings in reinforced slopes are therefore needed. This paper proposes an analytical method for estimating the increase in bearing capacity gained from the included horizontal strips or ties of tensile reinforcing in the foundation soil below the footing built near the crest of a slope. A failure mechanism, including the concept of'wide slab effect', adopted in the present study for analyzing the bearing capacity of foundations in reinforced slopes, is established through the observed model test behaviors described by Binquet SE Lee and Huang et al, and the Boussinesq solutions. The analytical results are then compared with the experimental data described in the paper by Huang et al. Also in order to properly evaluate the soil reinforcement interaction, typical pullout test values of the apparent friction coefficient, which usually vary with depths owing to both the increase of the shearing volume and the increase in local stress caused by soil dilatancy, are analyzed and related functionally. Furthermore, analytical parametric studies are carried out to investigate the effect and significance of various pertinent parameters associated with design of reinforced slope foundations. Keywords : Bearing capacity, Reinforced slope, Slab effect, Friction coefficient.

In order to prepare for the coming twenty-first century and to meet changing social demands and health needs, it is necessary to improve the curriculum through development of new conceptual frameworks. The purposes of this study were : 1) to assess the needs of the curriculum of the students, the faculty, the graduates, and the nursing supervisors and head murses ; 2) to develop the conceptual framework which includes philosophy and goals of nursing education based upon needs assessment ; 3) to develop level objectives ; 4) to identigy the contents of the curriculum ; 5) and to develop the faculty. The curriculum was assessed and developed from April, 1995 to March, 1996 through twenty four weekly meetings, two seminars, and two workshops. The process and results of this study are as follows : 1. A needs assessment of the present curriculum was done of the 194 students, 177 graduates, 14 faculty members, and 60 nursing administrators in 5 main areas (objectives, planning and organization, teaching-learning process and methods, evaluation, revision of curriculum). The results showed that there were many descrepancies between expectations and actual situations in all the groups and in all the areas. This implies that there was a necessity for total curriculum revision. 2. To develop the conceptual framework, 1) the core concepts were identified(man, health, environment, and nursing) on the basis of the existing educational philosophy and educational objectives of our school, elicited by group discussions using the nominal group method, one of the needs assessment methods, the philosophy and objectives were restated. 2) Six essential componednts were indentified for the conceptual framework from the restated philosophy and objectives ; nursing process, communication, professional roles, client, health, and nursing. The vertical theread consists of the client and health/nursing ; and the horizontal thread consists of nursing process, communication, and professional roles. 3. The contents of the curriculum were selected on the basis of the educational objectives and organized according to the conceptual framework. 4. The level objectives were then restated. It is expected that the objectives of our school will be accomphished through developing the courses, choosing and Implementing, more effective teaching-learning methods, and evaluating the efficacy of changes implemented. The most important factor will be to continually upgrade the faculty and their teaching skills.

This paper presents an investigation on the ultimate behavior of a transmission tower using nonlinear analyses inconsideration of residual stress and initial imperfection. Main members, such as main post, horizontal member and diagonal member of the transmission tower were modeled using beam element. Moreover, submembers of the transmission tower were modeled using truss element. ABAQUS (2004) program was used to perform finite element analyses. Initial condition options of the ABAQUS program considering initial stress and imperfection were used in this study. Before performing the analysis of the total transmission tower, simple angle section models using beam or plate/shell element w ere investigated to verify the appropriateness of ABAQUS analysis models and options. According to the verification results, the beam element was used for nonlinear analyses of the transmission tower. From nonlinear analyses results, buckling failure was in the main member of the leg part because of ${P-{\triangle}}$ effect at that point. Also, this paper includes significant results to define real structural failure modes and quantitative values. This study should be used in the development of a reasonable and economic design method for transmission towers.
