  • The present study investigates the spray characteristics of water mist nozzle with mid-low pressure for fire suppression. The examined nozzle types are swirl and spiral nozzle. The result shows that K factor of water mist nozzle is much smaller than those of general sprinkler. Spray angle of spiral nozzle is largest and more than $150^{\circ}$. SMD(Sauter Mean Diameter) of water mist nozzles is ranged between 100 and 200$\mu\textrm{m}$through measuring by image processing method. The spray pattern of spiral nozzle represent that water flux of first stream is 2 times larger than that of second stream. This study will contribute better understandings of the water-mist spray characteristics and useful daia for developing the water-mist nozzles.

  • In order to provide the basic data for planning of housing safety, the actual conditions of home accidents were analyzed. As research data, the medical charts of patients on the general hospital in the large city in two years 1987 and 1992 were used. The rate of home accidents increased in 1992. Children had more accidents than others and single family dwellings were the predominant place of accidents. The accidents slip frequently occured(21.1%), with respect to the place, room was the main place of accidents(40.5%), the accidents in a living room and a kitchen increased in 1992. 59.2% of the total patients were slightly injured, the faulty design was the main cause of the accidents and the acciednts by the personal factor increased in 1992. In the next study(III), I'm going to analyze the relationships among types of accidents, places of accidents, defrees of accidents, causes of accidents, and the personal characteristics of patients.

  • If there is a water flow with a range of temperature inside a pipe, the wanner water tends to float on top of the cooler water because it is lighter, resulting in the upper portion of the pipe being hotter than the lower portion. Under these conditions, such thermal stratification can play an important role in the aging of nuclear power plant piping because of the stress caused by the temperature difference and the cyclic temperature changes. This stress can limit the lifetime of the piping, even leading to penetrating cracks. Investigated in this study is the effect of thermal stratification on the structural integrity of the pressurizer surge line, which is reported to be one of the pipes most severely affected. Finite element models of the surge line are developed using several element types available in a general purpose structural analysis program and stress analyses are performed to determine the response characteristics for the various types of top-to-bottom temperature differentials due to thermal stratification. Fatigue analyses are also performed and an allowable environmental correction factor is suggested.

  • Recently, The Building has became high rising and large scaling according to development of economy in domestic and other country, also the building has increased a variety of functions of insulation for warmth. and it has a symbol of economic growth, but it has risk factor for disasters such as fire. this hazards include not only general building but also residential building. Recently, Grenfell Fire that occurred in England has increased in combustion to the 24th floor of the 1st floor for 1 hour. it resulted in 80 deaths and 79 missing persons. In this study we suggest basic data of residential building for fire safety design related to domestic environment to analyze the problem of Grenfell Tower.

  • The purpose of this study is to understand the relation of peer group caring interaction, Professional self-concept, and Nurses' Retention. The subjects of this study are 133 nurses who have worked for more than three months at five general hospitals with more than 300 beds in S city. As a result of the study, nurses' retenstion was higher than those of under 25 years of age between 30 and 35(F=3.313, p=.039).The professional self-concept of hospital nurses has been identified as an influence factor of intent to serve. Professional self-concepts have been shown to be better with higher peer-care and consideration(r=.397, P=.004). The peer group caring interaction behavior can occur not only between colleagues but also between managers. Therefore, it is necessary to proceed with the manager's group caring interaction as a follow-up study.

  • The use of economic incentives to improve H&S performance in the construction industry in general, has been investigated by various scholars. However, few studies have looked at the impact of economic incentives on construction clients especially in the developing world. Therefore it was necessary to investigate specifically the impact of the economic incentive on client's H&S performance. Economic incentives are considered to be a proactive way of improving H&S performance. The investigation was conducted using a Delphi technique to determine the impact significance of the economic incentive or disincentive on construction clients' H&S performance. Findings from the study were that the economic factor had critical impact significance on clients' H&S performance. Further clients were 'very likely to' implement various H&S elements as a result of the economic incentive and disincentive. The paper will report on the findings from an analysis of impact significance of the economic incentives on clients. It will underscore the point that economic incentives or disincentives on construction clients are necessary to encourage them to actively participate in H&S performance improvement.

  • The Navigation Streets Map that directly supplies information for a driver plays an important role in Car Navigation System(CNS). Therefore, cause the compatibility, preference, visibility, and readability of the navigation streets map will be hold sway over driver's information acquisition, safety, and performance in CNS, it is important that designer's requirements should be analyuzed for ergonomic design of navigation streets map. Especially, there are differences between the topographical objects marking method and that of the general map in a navigation streets map. Because much information is marked in a narrow space, it is important that the text information should be done in navigation streets map. Also, because it is a important factor to mark the text format for the marking method of the topographical objects, the design requirements will be drawn out through the factor analysis for the text marking method. And when ergonomic designers are doing, this result will be basic research for developing driving simulator of CNS and it will be a ergonomic guideline of navigation streets map.

  • The purpose of this study was to investigate purchasing variables in the organic food consumption level in Busan. To achieve this purpose, 240 residential women who are organic food consumers were chosen. Among them, 149 women took part in the study. The questionnaire was composed of three parts: 8 demographic characteristics, 9 organic food purchasing conditions, and 22 purchasing variables. The research was continued from August 20th until September 10th, 2007. To derive the results, descriptive analysis, factor analysis, and ANOVA were used by spss 14.0. To sum up the results, three organic food consumption groups were classified into high, middle, and low consumption levels depending on buying condition for organic material. For the factor analysis, 5 factors were named as confidence, quality, safety, appearance, and economy. On the high consumption level, economy factor was highly important than other groups. In general, price would be a more sensitive factor, so they answered the adjusted price range; 52 participants said under 10%, 22 between 11% and 20%, and 17 over 40%.
