The concept and definition of nursing and her role have been changing in accordance with the socio-cultural factors of the initial society. At present, nursing is conceptualized as a health care profession assisting man to restore, maintain and promote health by providing knowledge, wilt strength and resources through various processes of interaction. Man′s behavior, of individual and group activities for health inclusive, is driven by the initial man′s value orientation. The purpose of this study is to investigate the value orientation regarding health of rural health center milieu in order to give data for; 1. the planning for the delivery of community nursing service, 2. the health education plan at all level of nursing care activities, and 3. the planning of curriculum for nursing education. A hundred opinion leaders among the labor population residing in rural areas (P-group), hundred and six professional nurses at rural health centers (N-group) were indirectly interviewed through questionaries. And ninety five of N-group were interviewed likewise of their perceptions of P-group (NP-group) from July 15, to October 15, 1974. The result is as follows: 1. Maintenance of health is revealed to be the most valued component for man′s happiness in all the three groups. (P-group: 7.30 S. D.=1.31), (N-group :7.84 S. D. =49), and (NP-group : 5.93 S. D. =2.28) 2. The average value score of the maintenance of health revealed significant difference by P〈.001 level between each of the three groups. (Between N-group and P-group : T= -4.07 P and NP ; T=-6.93, N and NP: T=-9.35) 3. Basic health maintenance activities necessary for maintenance and promotion of personal health were moderately valued by all the three groups, P-group ; 3.74 (S. D. =.43) , N-group: 3.52 (S. D. =.34), NP-group: 3.07 (S. D. :.55) Among the 8 categories of basic health maintenance activities, "food intake" was highly valued by P-group (mean value score; 4.00 S. D=.51) , "exercise and rest" and "personal cleanliness" was highly valued by both P-group (4.02, 4.08) and N-group (4.08, 4.22). 4. The mean value score of basic health maintenance activities revealed significant difference by P〈.001 level between each of the three groups (between P-group and N-group: T=-4, 07, N-and NP: T=-6.93, P and NP T=-9.35) 5. Among the 30 questionaries, dynamic activities for health maintenance were more valued in comparison to passive activities in an tile three groups. 6. In N-group, correlation between the value of basic health maintenance activities and the personal health status personal revealed moderate significance. Correlation between the value of basic health maintenance activities and the age revealed low significance. 7. In group, correlation between the value of basic health maintenance activities and; perception of personal health status revealed non significance, between the age and sex revealed low sign affiance, and between the educational status revealed moderate significance. Recommendations are as follows ; 1. The efforts towards alteration of value orientation concerning health in general in community nursing practice de focussed be that of family Planning. 2. In order to prepare professional nurses competent in understanding individual and group, social science and behavioral science be strength ended in planning nursing curriculum. 3. Milieu of nursing experience during nursing education be Planned to begin at simple nursing problem and move towards complex, f. e. home care towards health crisis situation in order to achieve dynamic role mastery.

During image-guided radiation treatment of lung cancer patients, it is necessary to track the tumor motion because it can change during treatment as a consequence of respiratory motion and cardiac motion. In this paper, we propose a method for tracking the motion of the lung tumors based on the three-dimensional image information from planning 4D MDCT and treatment 4D CBCT images. First, to effectively track the tumor motion during treatment, the global motion of the tumor is estimated based on a tumor-specific motion model obtained from planning 4D MDCT images. Second, to increase the accuracy of the tumor motion tracking, the local motion of the tumor is estimated based on the structural information of the tumor from 4D CBCT images. To evaluate the performance of the proposed method, we estimated the tracking results of proposed method using digital phantom. The results show that the tumor localization error of local motion estimation is reduced by 45% as compared with that of global motion estimation.

In this in this thesis, we have proposed the Kor-231 which compared with Hata by dividing 4 classes and 8 details, which based on that the area subdivision which is defined by the City planning Regulation of Korea classified on its rate of building-to-land, floor area and distance between buliding and botanical coefficient. The experiments are carried out at the point of the RMS delay spread and the recerived power in the two kinds of geographical areas, LOS(Line of Sight) and N-LOS(Non Line of Sight). When the measured result is compared with Kor-231 model, we can catch the result that received power are 25.5dB and 14.5dB, the RMS delay spread are 101ns and 35ns and N-LOS received power are 4.1dB and 1.6dB. So we have certified that it is well due to the result analyzed into the difference of the RMS delay spread from 74ns to 200ns.

Safety of workers and productivity in construction site are affected according to the conflict status of work spaces which are performed at a time. The interference among the work spaces in construction site should be minimized because it becomes a blocking factor that causes construction delay and low productivity. Those factors can be managed by reasonable H&S (Health & Safety) practice. This research suggests the requirements of H&S practice and rules to establish the strategy of H&S management based on the literature reviews related to H&S rule. The suggested H&S rule can be visualized for searching space conflict point if the rule is linked with visual simulation tool. Accordingly the research results can be used for improving and visualizing construction productivity by work space control in 4D/nD CAD system.

This paper presents the results of parametric analyses to compute the axial capacity of a suction pile using 2D and 3D finite element approaches. The study is intended to simplify the process of analyzing suction piles from 3D to 2D model. The research focuses on obtaining the coefficient to be applied into the 2D model in order to obtain results that are as close as possible to the 3D model. Two 2D models were used in the analysis, namely the plane strain and axisymmetric models. The analyses were performed using two actual offshore soil data of the North and West Java Indonesia. The study reveals that the simplification of model through 2D Finite Element is achievable by applying the appropriate coefficient to the stiffness parameters. The results show that the simplified model of the 2D FEA provides more conservative results (with the difference between 2% to 7%) than the 3D FEA.

In this paper, the derivation of protection ratio is newly proposed for the detailed planning of frequency coordination in microwave relay networks, and computed results for protection ratio of co-channel and adjacent channel are illustrated over the actual system and its frequency. It is shown that the suggested method based upon availability prediction can be expressed in terms of composite fade margin, interference-to-noise ratio(I/N), net filter discrimination, and system parameters. According to results, for 6.7 GHz, 60 km, 64-QAM, and I/N= -6 dB at BER $10^{-6}$, composite fade margin and co-channel protection ratio provide 25.5 and 50.7 dB, respectively. Also, net filter discrimination and adjacent channel protection ratio are obtained as 26.3 and 24.4 dB, respectively, at the first adjacent channel of 40 MHz. The proposed method provides some merits in computing protection ratio for microwave relay networks in view of an easy extension and practical applications considering more detailed and various system parameters.

억새(Miscanthus spp.)는 우리나라 등 동아시아가 원산이며 바이오매스량이 많아 바이오에너지 원료작물로서 잠재성이 크기 때문에 2세대 바이오에탄올 생산 원료로 주목을 받고 있고, 축산깔개 및 토양개량제 등으로도 이용되고 있다. 미국과 유럽 등에서는 생태계 교란 방지를 위해 4배체 물억새(M. sacchariflorus)와 2배체 참억새(M. sinensis)의 종간 교잡 이질 3배체인 불임성 억새(M. x giganteous)을 주로 재배하고 있으나, 단일 유전형의 품종으로 병해충과 자연재해에 취약하여 다양한 억새 품종의 개발이 시급한 실정이다. 본 연구는 억새를 재료로 하여 반수체 및 배수체 확보를 통한 배수성 별 특성 평가와 함께 기내배양을 통해 탈분화 및 재분화 시스템을 구축하여 억새의 육종 효율을 높이기 위해서 실시하였다. 억새 종자로부터 캘러스의 유도는 MS배지와 N6배지에 1mg/L 2.4-D를 첨가하였을 때 비배발생 캘러스(nonembryogenic callus)가 유도되었고, N6배지에 3~5 mg/L 2,4-D를 첨가하였을 때 배발생 캘러스(embryogenic callus)가 발생하였다. MS배지보다는 N6배지에서 캘러스 유도율이 높았으며, 식물생장조절제로 2,4-D와 BA 조합처리 보다 2,4-D 단용 처리하였을 때 캘러스 유도율이 더 높았다. 억새 종에 따른 캘러스 유도율은 물억새가 25.2~49.3%, 참억새는 30.3~52.0%였고 거대억새는 62.6~81.1%로 나타났다. 억새 신초 및 줄기로부터의 캘러스 유도율은 물억새가 4.4~17.2%, 참억새는 1.8~7.7%, 거대억새는 15.3~19.9%로 나타나 종자에 비해 매우 낮았다. 미성숙화기로부터의 캘러스 유도는 억새 종에 따른 차이가 없었으며, 3mg/L 2,4-D 첨가 배지에서 캘러스 유도율이 비교적 낮았고(60~80%), 1mg/L와 5mg/L의 2,4-D가 첨가된 배지에서 캘러스 유도율이 높게(90~95%) 나타났다.

Lactobacillus amylovorus are known to exist in the intestinal flora of healthy cattle or pigs. The L. amylovorus strain 1394N20 was isolated from the feces of the Hanwoo calf (Bos taurus coreanae). The genome of strain 1394N20 consists of a single circular chromosome (2,176,326 bp) with overall guanine + cytosine content of 37.8 mol%. Moreover, 2,281 protein-coding sequences, 15 rRNAs, and 65 tRNAs genes were identified in the chromosome based on the results of annotation. The bacterium has a gene encoding endoglucanase, an enzyme that hydrolyzes the 1,4-β-D-glycosidic linkages in cellulose, hemicellulose, lichenin, and cereal β-D-glucans. Genomic sequencing of L. amylovorus strain 1394N20 reveals the immense potential of the strain as a probiotic with nutrient digestibility.
