Nurses in today's challenging health care settings need to be skilled critical thinkers and clinical experts. The nurse must be able to use a broad knowledge base to mobilize resources, coordinate actions and evaluate outcomes in complex new situations. So the national licensing examination for registered nurses is change to improve the quality of professional competency of nurses in Korea. Prior to this, learning objectives should be developed and improved periodically. The purpose of this study is to describe the nursing competency to provide base line data for developing learning objectives in adult health nursing. This study was conducted by means of a questionnaire which was developed by the researcher after reviewing the literature. The questionnaire was based on learning objectives which were developed by a nation-wide nursing faculty majoring in adult health nursing. The subjects were 45 nurses in a middle level hospital. The collected data were treated using SPSS Win 7.5 Statistical Package so as to obtain such descriptive statistics as mean score, frequency, and to test reliability test, nonpar-Friedman test. To summarize the major findings in this study, it showed the scope of nursing competency and can guide the direction of study and methodological criteria to develop learning objectives. Recommendations for further research are: firstly, it is necessary to state learning objectives with learners' behavioral terminology; secondly, to overcome locality in scope of this study, there is a need to analyze with nation-wide sampling by an in-depth statistical analysis; thirdly, because the subjects of this study are mostly three-year graduate nurses, there is a need to compare this study with other studies of different subjects.

Jewelry has recognized as a part of independent formative arts of fashion with the change modern man's cognition for the fashion. It is a great important section to express fashion image. So, many corporations design and develop the jewelry by themselves to maxmize their fashion image. Among the so many kinds of jewelry, especially the necklace is located beneath the face and linked as a part of fashion, so it frequently has showed in Fashion Collection. Like this Fashion and jewelry enact each other and share their esthetic features but, it is insufficient the study of fashion linked with the jewelry. In this study, we defined the words which is using confusedly according to jewelry forms what researched by others. In addition, we tend to study the effect of that the form, hue and character of materials of necklace that is expressed in fashion collection influence fashion image. The method of this study is comprised with precedent studies and analysis of necklace photos in fashion collection. For the analysis of data, we implement content analysis and statistical analysis using SPAW Statistics 18(frequency analysis, percentage, cross-tabulations, $X^2$-test). Because the hue and the form of necklace take a great role to make fashion image with the sense of its eyesight, its effective coordination go up the delicate feelings with the form, hue and quality of the fashion. Especially, the hue is the essential element of formative characteristics to express visual image. The necklace had coordinated more frequently in S/S than F/W, it means that more light and simple fashion let ornamental beauty could express by the necklace. So, it is very effective things that we predict the trend of fashion, then, coordinate with well-matched necklace.

Virtual Brain-endoscopy is an effective method to detect lesion in brain. Brain is the most part of the human and is not easy part to operate so that reconstructing in 3D may be very helpful to doctors. In this paper, it is suggested that to increase the reliability, method of matching 3D object with the 2D CT slice. 3D Brain-endoscopy is reconstructed with 35 slices of 2D CT images. There is a plate in 3D brain-endoscopy so as to drag upward or downward to match the relevant 2D CT image. Relevant CT image guides the user to recognize the exact part he or she is investigating. VRML Script is used to make the change in images and PlaneSensor node is used to transmit the y coordinate value with the CT image. The result is test on the PC which has the following spec. 400MHz Clock-speed, 512MB ram, and FireGL 3000 3D accelerator is set up. The VRML file size is 3.83MB. There was no delay in controlling the 3D world and no collision in changing the CT images. This brain-endoscopy can be also put to practical use on medical education through internet.

The purpose of this study was to investigate the effect of the upper body in order to increase a propulsive force in the old's walking. The subjects were each 10 males, the latter term of the aged and former term of the aged. There were three walking speeds of slow(about 5km/h), medium(about 6km/h), and maximum speed(about 7km/h). The subjects walking 11m were filmed the 5m section (from 3m to 8m) by 2-video cameras using three dimensional cinematography. And we computed different mechanical quantities and especially computed the relative momentum in order to achieve this study's aim. In this study, we was able to acquire some knowledge. The step length and step frequency increased in proportion to the walking speed, and the faster walking speed, the shorter ratio of supporting time( both legs supporting time/one step length time). When it was one leg support phase, the torso was indicated to generate the momentum in order to produce the propulsive force of walking. The upper and lower body had a cooperative relation for walking such as keeping step rate with the arms to legs and maintaining the body balance. The opposition phase for upward-and-downward direction of the torso and arms in walking was functioned to prevent the increase rapidly toward vertical direction of the center of gravity. The arms had contributed to coordinate the tempo of legs and the posture maintenance of the upper body. And by absorbing the relative momentum from the upper torso with arms to the lower torso, it had the rhythmical movement on upward-and-downward direction reducing the vertical reaction force. On account of the relations of absorption and generation of the propulsive force and the production of vertical impulse in the lower torso when walking by maximum speed, it was showed that the function of lower torso was come up as important problem for the mechanical posture stability and propulsive force coordination.

Soil physical and chemical characteristics, soil potential denitrification rates (PDR), community composition and nirK-, nirS- and nosZ-encoding denitrifiers were studied by using MiSeq sequencing, quantitative polymerase chain reaction (qPCR), and terminal restriction fragment polymorphism (T-RFLP) technologies base on short-term (5-year) tillage field experiment. The experiment included four tillage treatments: conventional tillage with crop residue incorporation (CT), rotary tillage with crop residue incorporation (RT), no-tillage with crop residue retention (NT), and rotary tillage with crop residue removed as control (RTO). The results indicated that soil organic carbon, total nitrogen and NH₄⁺-N contents were increased with CT, RT and NT treatments. Compared with RTO treatment, the copies number of nirK, nirS and nosZ in paddy soil with CT, RT and NT treatments were significantly increased. The principal coordinate analysis indicated that tillage management and crop residue returning management were the most and the second important factors for the change of denitrifying bacteria community, respectively. Meanwhile, this study indicated that activity and community composition of denitrifiers with CT, RT and NT treatments were increased, compared with RTO treatment. This result showed that nirK, nirS and nosZ-type denitrifiers communities in crop residue applied soil had higher species diversity compared with crop residue removed soil, and denitrifying bacteria community composition were dominated by Gammaproteobacteria, Deltaproteobacteria, and Betaproteobacteria. Therefore, it is a beneficial practice to increase soil PDR level, abundance and community composition of nitrogen-functional soil microorganism by combined application of tillage with crop residue management.

This study reports on the geometry optimizations and electronic structure calculations for methyl pyropheophorbide (MPPa), tropolonyl methyl pyropheophorbides (TMPPa, ITMPPa), and cationic tropolonyl methyl pyropheophorbides ($TMPPa^+{{\cdot}BF_4}^-,\;ITMPPa^+{{\cdot}BF_4}^-,\;TMPPa^+,\;and\;ITMPPa^+$) using Local Spin Density Approximation (LSDA/ 6-31G*) and the Restricted Hatree-Fock (RHF/6-31G*) level theory. From the calculated results, we found that substituted cationic tropolonyl groups have larger structural effects than those of substituted neutral tropolonyl groups. The order of structural change effects is $ITMPPa^+ > ITMPPa^+{{\cdot}BF_4}^-$ > ITMPPa, as a result of the isopropyl group. Because it is an electron-releasing group, the substituted isopropyl group electronic effect on a 3-position tropolone increases the Highest Occupied Molecular Orbital and Lowest Unoccupied Molecular Orbital (HOMO-LUMO) energy gap. It was constituted that the larger the cationic characters of these photosensitizers, the smaller the HOMOLUMO band gaps are. The orbital energies of the cationic systems and the ions are stronger than those of a neutral system because of a strong electrostatic interaction. However, this stabilization of orbital energies are counteracted by the distortion of chlorin macrocycle, which results in a large destabilization of chlorin-based compound HOMOs and smaller destabilization of LUMOs as shown in TMPPa (ITMPPa), $TMPPa^+{{\cdot}BF_4}^- (ITMPPa^+{{\cdot}BF_4}^-),\;and\;TMPPa^+\;(ITMPPa^+)$ of Figure 6 and Table 6-7. These results are in reasonable agreement with normal-coordinate structural decomposition (NSD) results. The HOMO-LUMO gap is an important factor to consider in the development of photodynamic therapy (PDT).

The Korean Population Control Program has been implementing under the jurisdiction of the Ministry of Health and Social Affairs through an existing network of health centers. This arrangement was successful in bringing population growth down to targeted level by the end of the Fourth Five Year Economic Planning, 1981. It is expected, however, that future goal will be harder to reach due to difficulty of reducing traditional family size norms further and to the projected increasing the number of eligible couples as the past Korean war baby boom generation enters the reproductive activity in the next few years. The recognition of the need for modification of population policy is increasing. The 1980 census shows that the total number of population reached approximately 38.5 million with 1.57 per cent of the growth rate. It was projected that the size of Korean Population will reach around 42 million and 51 million in 1986 and 2000 respectively. Furthermore, there is some argument as to whether decline in the birth rate in Korea is too slow to meet government target. Hence, a new development of population policy and greatly increased amount of effort will be needed in order to achieve Zero Population Growth Rate before the year 2050. The development of future national population policy and its related area are recommended as follow: 1. It is highly recommended that the population planning law governing both vital events of birth and death and population migration should be legislated. 2. The National Population Policy Council, Chaired by Deputy Prime Minister should be activated to implement and coordinate population program within ministries. 3. Responsible organization of population and family planning program should be established as a Bureau unit at central government level. 4. For the improvement of national vital registration, an existing system should be studied and developed.

지적도는 모든 지도중 가장 큰 대축척 지도이며 토지에 대하여 필지별로 지번, 위치 및 경계 등 소유권의 범위를 등록하는 것으로서 국민의 기본권리인 토지에 대한 소유권과 그 이용을 보장할 수 있는 가장 기본적인 특성을 가지고 있다. 도형자료인 현재의 지적도는 1910년 토지조사사업에 의하여 실제 토지필지를 1/1,200로 축소하여 도면에 등록한 도해지적으로 제도오차, 축척오차, 신축오차, 도곽접합 등의 기술적인 오차와 측량을 할 때마다 각기 측량사에 따라 개인오차의 누적으로 성과결정에 있어서 차질을 가져다주고 있다. 따라서 이러한 문제를 해결하기 위하여는 지적재조사사업이 가장 바람직하지만 복잡한 과정을 거쳐야 함으로 그 이전에라도 축척변경사업을 통하여 새로운 지적체계로서 토지이용상태에 따라 토지의 경계를 수치좌표로 등록하는 수치지적체계로 전환하여 지적측량의 정확도와 정밀도를 높여 지적불부합지에 대한 민원을 해소함으로써 재산적 가치를 증대할 뿐만 아니라 국민의 소유권 보호 및 양질의 서비스 개선에 그 목적이 있다. 본 연구에서는 해당지역의 지적도를 독취, 정도곽으로 보정하여 일필지를 공부상면적의 공차범위 이내로 조정한 후 현형도와 지적도를 조정(Orientation)하여 좌표를 저장하였다. 일필지 좌표결정 방법에는 CAD기능을 이용하여 컴퓨터의 모니터에서 지적도를 이동 및 회전함으로써 위치를 결정하는 방식, 모니터상에서 국부적으로 위치를 결정하는 방식 및 디지타이져상에서 결정하여 모니터상에서 조정하는 방식있다. 현실적으로 국부적인 방법이 합리적이라고 생각되어 모니터상에서 조정(Orientation)하여 국부적으로 좌표 위치를 결정하는 방법으로 연구하고 성과를 비교, 검토하였으며, 그 결과 다음과 같은 결론을 얻었다. 1. 지적도면은 토지조사사업 한지를 배접한 켄트지를 사용함으로써 종이의 신축으로 인하여 정도곽으로 보정을 하면 독취면적은 대부분 공부상면적보다 늘어났다. 2. 좌표의 이동량이 일률적이지 못하므로 기초점에 대한 문제라고 생각되며, 따라서 도해지적을 수치지적으로 전환함에 있어서 가장 우선되어야 할 사항이 기초점 정비라 하겠다.
