Purpose. This study of purpose was to to compare of Aerobic and Anaerobic Capacity between Sasang Constitutions and ACE Gene Polymorphism. Methods. 24 healthy males were participated in this experiment who were in their twenties and had no disease, then they were divided by ACE type and by Sasang constitutions with QSCC II. According to these group, the body compositon, Aerobic capacity including VO2max, Anaerobic Capacity were measured. Results. In this study, According to ACE type, ID type were 8, II were 8 and DD type were 8 persons. According to ACE type, there were significant difference among type, especially, II, ID type more than DD. II type is more higher than any type and DD type is lower in the ratio of Blood Lactic recovery. DD type was more excellent than other type in Anaerobic power. According to Sasang Constitutions, there were 8 SoYang, 5 Taeum, 11 Soeum and then no TaeYang constitution. In Aerobic capacity, Taeum constitution had significantly high means and Anaerobic threshold. In the ratio of Blood lactic recovery, Taeum constitution was excellent and SoYang had poor recovery capacity. SoYang had more excellent than other constitution significantly in Anaerobic capacity. Comparing ACE type with Sasang constitution, Soyang constitution included 4 ID types, Taeum inclued 2 II types and 2 ID types then Soeum included 6 DD types. Compared of Aerobic and Anaerobic capacity between Sasang constitutions and ACE type, Soyang constitutions were similar to ID type, Taeum similar to II type and ID type and then Soeum were DD type. Conclusions. This study had made it clear that there were similar feature between ACE type and Sasang constitutions. Also it's possible to predict the Aerobic capacity that may be foreseen by ACE type with Sasang questionnaire method but not Anaerobic capacity.

Recently, vessel's average speed in the sea becomes fast because of the increasing of high-speeds vessel like a container ship and ferry. So, it is considered that speed control in the korean narrow waterway isn't the proper vessel traffic management, now. And, there is a rare paper studied about speed control quantitatively and numerically, especially speed control is discussing continuously, as abrogation of Incheon Port's speed control and alleviation of Kwangyang Port's speed control a according to navigating mariner's request. After this paper replayed the navigation traffic flow in the straight waterway using marine traffic flow simulation, the Environmental Stress Model is introduced to evaluate difficulty of each vessel's traffic.

The main objective of this study is to develop an discrete optimization algorithm of plane steel frames with rigid using second-order-elastic-plastic hinge analysis which is considering panel zone. Conventional analyses of steel frame are usually tarried out without considering the effect of panel zone deformation on frame behavior The validity of this model is established by comparison without panel zone on joint models is analyzed numerically to demonstrate the importance of using realistic models in steel frame analysis. The objective function is taken as Weight of steel frames and the constraints we formulated based on AISC-LRFD(1994). The validity of the developed algorithm we demonstrate by comparing the result with those of SAP2000. The result of the study indicates that the optimal design algorithm considering of panel zone behavior more economic design than simple steel frame design methods.

Recently, ships' average navigation speed become faster than before because of the increasing of high-speeds vessel including container ships and passenger-ferries. So, it is considered that the speed limit in the navigation channel in Korea isn't proper for vessel management in these days. Also, there is rare paper studies about the speed limit quantitatively and numerically, especially the speed limit is discussing continuously, as abrogation of Incheon Port's speed limit and alleviation of Gwang-yang Port's speed limit according to the requests by the navigating mariners. Consequently this paper deals with the effectiveness of speed limits using the Environmental Stress Model, after replay of the navigation traffic flow in the straight waterway using marine traffic flow simulation technique.

The behaviors of steel-plate shear panels were investigated through an experimental and analytical study, using mild steel (S40). Steel-plate shear panels buckle at small loads, and their strength is based on the shear panel's postbuckling strength due to tension field action. In design practice, however, the capacity of steel-plate shear panels is limited to the elastic buckling strength of shear panels. Th e National Standard on Limit States Design of Steel Structures, CAN/CSA-S16.1-94 (1994) contains a guideline for the analysis of thi n, unstiffened, steel-plate shear walls using the strip model. In this paper, the structural capacity of shear panels was evaluated using the results of the experiment and of the strip model analysis.

화재감지기는 연기감지기는 이온전류의 변화량을 감지하는 이온화식 연기감지기와 발광부와 수광부로 이루어진 챔버내에 연기에 의한 광량의 변화를 감지하는 광전식 연기감지기로 구분된다. 국내에서는 광전식 연기감지기가 더 많이 사용되고 있는데 이러한 광전식 연기감지기의 챔버내에 이물질이 침입하게 되면 비화재보를 발생시키게 된다. 본 논문은 연기감지기의 연기감지 챔버에 대한 비화재보를 감소시키기 위한 신뢰성 시험에 대하여 논한 연구이다. 본 연구에서는 광전식 연기감지기의 신뢰성을 검증하는 방법으로 UL 268 등에 규정되어 있는 먼지, 즉, 분진에 대한 신뢰성을 검증방법을 제시하였다. 먼지에 대한 신뢰성 검증을 보다 적절하게 하기 위하여 분진챔버로 분진을 반복적으로 폭로됨에 따른 감도성능 변화를 분석하는 방법이 필요할 것으로 사료된다.

In order to educate learners who cope with quickly to the information society of twenty-first century, it is required to develop ability to make a plan oneselves, solve the problem by collecting and examining information with various method. The purpose of this study is develop a constructive information searching model, present contents meet with learner's grade then help teacher and learner can search information that needed teaching and learning. In addition to it, this study enable learners to participate learning by self-directing, at the same time cope-learn throuth interaction with members, design of web-site that can be shared. exchanged new various information.

In case of the crime occurrence preliminary investigation is very important. Police perform on-site first responders throuth the First Responders Manual and 112 information system. But recently the failure cases of preliminary investigation happened. Social criticism was castrated for the police that roundup succeeded but failed to protect the victims of crime. Avoiding these accidents, improvement of preliminary investigation is required. Accordingly local police personnel system improvement, improvement of reporting systems, Integration of 112 information and 119 information, improvement of seizure search regulations, victim care, crime response exercises reinforcement is required for the protection of criminal victims in preliminary investigation.

The purpose of this study is to theoretically explore the pedagogical meaning of Flipped Learning (FL) through the lens of Bakhtinnian Dialogism. Flipped learning has emerged based on technological development, which enables educators to reorganize educational space and time. In the new converged time and space, teachers changed the activities in and out of classes, flipped lectures with students' activity, and redefined the role of teachers and students. These dialogical characteristics of FL results in several educational consequences: first, underscoring educational dialogue, second, extending the participation in the dialogical chain, third, deconstructing the existing authority of knowledge, and escalating the self-directedness of learners.

Privacy-right infringement using unmanned aerial vehicle (UAV) usually occurs due to the unregistered small UAV with the image data processing equipment. In this paper we propose that privacy protection acts, Personal Information Protection Act, Information and Communications Network Act, are complemented to consider the mobility of image data processing equipment installed on UAV. Furthermore, we suggest the regulations for classification of small UAVs causing the biggest concern of privacy-right infringement are included in aviation legislations. In addition, technological countermeasures such as recognition of UAV photographing and masking of identifying information photographed by UAV are proposed.
