In this paper, we will treat the diagnosis problem to accurately determine fault types. The judgement of fault types is accomplished by observing the cluster newly formed with faults and clustering the input current waveforms to intrinsically show the conditions with the dignet that is a clustering algorithm. The types of input current waveforms are, however, constrained during normal operation, though it considers the load character. In case of faults. new clusters are generated outside the clusters. which appear during normal operation, because the input current waveforms of the induction motor are generated by the type which is not observed in case of faults. The diagnosis about the types of faults is essential to building a fault tree about the induction motor, and it removes the causes of the faults using a fuzzy logic. We, first, constitute a fault tree, which connects with the parts and the entire system of the induction motor, and investigate fault modes which can be generated from the fault tree and the relationship of the cause and the effect of each part (of the motor). Also, we distinguish the faults of each part by means of inducing the said of fuzzy relation equations encapsulating the relationship of the fault modes and each part.

The purpose of the study is to identify land use characteristics which have influence on residents' mental health. Land use and housing types indicators including green areas and parks were selected by analyzing the related environment and health researches. Research database for every variable from 33 neighborhoods in Jeonju city were established through National Health Insurance Corporation, where is available for getting mental and behavioral disabilities (F code) expenses. The relation between those indexes and mental health were analysed. The findings of this study are as follows : First, the higher price area like apartments and raw houses the residents lived in, the more expenditure of F-code was paid. It could be interpreted by the relatively high frequency of medical treatment and interests on the health. Second, the more green area except park were there, the more F-code expenditure was given, which could be explicated with the spatial co-relation between location of green area and apartments of Jeonju city. It was very high, and apartment element's affect on the F-code was much more than the green zone. Third, the nearer to park were the residents, the less F-code expenses was paid.

The present study was undertaken in moist temperate forest of Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim of the present study was to assess the physical properties of soils in relation to the forest structure and composition. Twelve forest types according to the altitude, slope aspect and species compositions were selected for the study. Physical properties of soil i.e., soil colour, soil texture (per cent of sand, silt and clay), moisture content, water holding capacity, porosity, bulk density (gm/$cm^3$) and void ratio were analyzed for three different depths viz., (i) 'upper' (0-10 cm), (ii) 'middle' (11-30 cm) and (iii) 'lower' (31-60 cm) in all the selected forest types. Phytosociological and diversity parameters viz. total basal cover ($Gha^{-1}$), stem density ($Nha^{-1}$), tree species richness, Simpson concentration of dominance and Shannon-Wiener diversity index were also calculated for each forest type. This study also provides the comparisons between the results of physical analysis of the present study with numerous other previous studies in the temperate Himalayan region of the Uttarakhand.

본 연구는 사회성측정(sociometry)을 통한 사회적지위의 유형에 따라 초등학생의 학업성취도에서 차이가 나타나는지를 알아보는데 있었다. 이를 위하여 K시에 소재한 S초등학교 6학년 201명을 대상으로 성별의 분리를 적용하여 7가지(인기, 평범, 배척, 높은 공격성에 의한 배척, 높은 수동성에 의한 배척, 무시, 양면성아동)로 지위유형을 분류한 다음, 각각의 지위집단 유형이 보여주는 학업성취도를 종속변인으로 하여 사회적지위 유형과 학업성취도간의 관계를 알아보았다. 5가지 사회적지위 유형을 분류하기 위하여 안이환(2007)에 의해 개발된 한국형 사회성 측정의 전산프로그램이 사용되었으며, 나머지 2가지 하위유형 분류는 실험조건에 따라 분류되었다. 종속변인은 2011학년도 1학기 중간학력평가 교과군별 점수였다. 성별과 지위유형에 따라 인문군(국어와 사회)과 자연군(수학과 과학)의 평균치가 비교되었다. 이때의 준거집단은 평범아동 집단이었다. 본 연구의 결과, 남자아동의 경우, 인문군과 자연군에서 모두 무시된아동의 성적이 가장 높게 나타났으며, 양면성아동이 인문군과 자연군에서 모두 가장 낮은 성적을 보였다. 여자아동의 경우에는 인문군과 자연군에서 모두 인기, 무시, 양면성아동이 유사한 범위에서 가장 높은 성적을 보였으며, 배척아동이 인문군과 자연군에서 모두 가장 낮은 성적을 나타냈다. 이러한 결과로 볼 때, 학업성취도는 초등학생의 사회적지위 유형과 관련되어 있음을 알 수 있었다. 관계지향적 학습형태를 지향하는 오늘날의 교육과정에 대한 흐름을 고려해 볼 때, 초등학생들의 학업성취도를 높이기 위한 사회적관계의 연구에 대한 필요성이 시사되었다.

The purpose of this study is to understand general perception of utilizing whale resources and preference for implementing whale watching tourism. This article examines perception of whale resources and identifies preferred types of the whale watching program in the feasibility of a whale watching tourism. And also analyzing the causal effect between perception of the whale resources and intention for participating in regarding the types of whale watching tourism. The results of this study showed that there are high interest in protecting and preserving of whale resources and low intention to resume the operation of commercial whale hunting. For utilizing of whale resources, we need to consider developing whale watching tour as ecotourism. The interest and watching for whale resources have a high level of relation with participating intention in whale tourism. Participation of whale tourism will be induced by developing new types of whale tourism to meet the interests for whale resources, This approach is hoped by authors to provide useful data for implementation of whale tour program and establishing improvement plan of whale tourism.

Single crystals of Mn-Zn Ferrite were grown by slow cooling method using Na2B4O7 as flux agent. The effects of flux content and cooling rate on the types of crystals, and the relation between supersaturation and growth mechanism were studied. As a result, the types of grown crystals occurred as plate, hopper and octahedral crystals. The occurrence of these crystal types was dependent on flux content. The habit was found to correlate with the growth rate and supersaturation. The lateral growth of a dendritic crystal is related to the twin layer. The growth of crystals from borax melts mainly occurred by the layer-spreading growth following corner and edge nucleation caused by high supersaturation in the melt. Especially, the plate crystals were produced on top of the melts. The hopper and octahedral crystals occurred at lower supersaturation than the plate crystals.

To mitigate the effects of cavitation and flashing, several types of orifices have been installed in the pipeline of new nuclear power plants. To review the effects of wall thinning caused by flow-accelerated corrosion by the types of orifices, which are cone and plate, and the relation between flow behavior and local wall thinning, experiments and numerical analyses for the downstream pipe of two types of orifices were performed. The experimental results in terms of static pressure obtained for the experimental facilities were compared with those of three-dimensional (3D) numerical analyses using the FLUENT code. As the results of review of flow-accelerated corrosion effects based on the experiment and numerical analysis, it was identified that the orifice of cone-type can be comparatively mitigated the effects of cavitation and flashing, but can not be mitigated the effect of flow-accelerated corrosion.
