In order to prepare the information needed to construct a reduction system for volatile organic compounds (VOCs) exhausted from ship-block paint-booths in a giant shipyard, VOCs in paint-shop airs were analyzed and compared to the components in paint thinners. Aromatic hydrocarbons containing eight and nine carbon atoms are known to be major VOC compounds found in shipyard paint-shops. The total hydrocarbon (THC(C7)) concentrations calibrated using toluene gas, were measured in block paint-shops with two photo-ionization detector (PID) meters, and the resulting THC(C7) data were converted to THC(C1) concentrations according to the Standard Methods for the Measurements of Air Pollution in South Korea. THC(C1) concentrations near the spray site ranged from 10 to 2,000 ppm, but they were less than 400 ppm near the walls of the paint-booth. The measurements of THC concentrations, based on the height of the monitoring sites, were related to the height of the target to which the spray paints were applied. The maximum concentrations occurred at almost the same height as the spray targets. When painted blocks had been dried-by warming with no spraying, the THC concentrations were 80~100 ppm.

This study was intended to grasp the housing unit plan which the residents preferred. The subjects were 100 housewives who lived in 85$m^2$ sized housing units in the New Apartment Complex, Gimhae. First, four elements of unit plan were selected on the basis of the results of the POE which was carried out for the same subject the size of master bedroom and living room, the openness of dining/kitchen from living room, the openness of living room from entrance, and whether or not a bathtub or a shower booth is in bathroom. Then, eight design alternatives of unit plan made by combination of these four elements according to orthoplan were visualized by computer media. This visualized tool was used for collecting data. The results of the study were as follows: The important determinants of the residents' preferences for unit plan were the size of master bedroom and living room and the openness of living room from entrance. The residents preferred the unit plan which living room was large and the view from living room to dining/kitchen was open. Also, the important elements were different according to the characteristics of the residents. Therefore, the housing alternatives which are flexible and optional would be desirable.

A colour-difference formulae would be based on a colour appearance model, but, So far, most colour-difference formulae in common use are based on empirical fits to data. Therefore, of the many proposed, none are completely satisfactory but advances have been made in recent years. A new color-difference data set has been produced with the aims of making a comparison of the advanced CIE Lab formulae as well as confirming the effect of color-difference. 416 low lightness pairs that have only lightness-difference were produced for evaluation of CIE Lab-based formulae on lightness-difference from glossy polyester fabric. The standard color-difference pair was prepared and used. It was neutral grey sample pair that has only lightness difference. The standard pair was used to investigate lightness tolerances. And grey-scale method used to evaluate visual assessment. CIE Lab coordinates of the samples were measured using a X-Rite 8200 spectrophotometer. Visual assessments were carried out using Gretag Macbeth The Judge II Light Booth. A study of color tolerances at low lightness was carried out and get avaliable some results.

Bathroom in apartment has the main functions of bath, washing hand and evacuation. The bathroom equipments for these functions are bathtub, shower booth, washbasin and toilet stool. Generally, these equipment are put together in one space, so it may cause people have trouble in using bathroom by other family members' occupation. Therefore the purpose of this study is to investigate the degree of preference about bathroom space fraction and grope for the connection with other spaces in apartment. The subject of this study were residents who live in brand apartments located in Seoul. The survey were carried out from november to December 2006. The data were analyzed through SPSS/PC+ using frequency, percentage and crossovers. The results of this study are as following, 1. A number of respondents would have trouble in using the bathroom by other family members' occupation once a week or more. The functional fraction of bathroom space is needed. 2. Close adjacency to Powder space, dress room is preferred. Coordination of washbasin and powder space is also needed. 3. Each separated spaces can be connected with other related spaces.

This paper introduces a simulation study regarding the design for the installation of Color Rescheduling Storage (CRS) in an automobile factory. In the painting shop the colors of vehicles are changed frequently according to the assembly schedule. When the color of a vehicle is changed from one to another, the cleaning process of painting-gun is necessary and it generates costs. Therefore many of the automobile manufacturers equip the CRS in front of the Top Coat Booth of the painting shop. The major objective of CRS is to reduce the change over cost in the painting process by grouping vehicles having same color. In this paper the configuration of CRS and the input/output algorithms are explained. The suggested system is verified using simulation models and experiments are conducted. Finally the best alternative is suggested by sensitivity analysis and evaluation of investment feasibility.

The plan of developing a fishing village and port will be indirectly funded by the government. In the short term, there will be five different multi-functional fishing village models which are based on the first industry to attach to the third industry of marine sports experience tourism. In the long run, they have to be reached gradually. The popular scenic spot of the marine sports experience tourism is made by human resources and fundamental installations considering that it must be done in unpolluted water. It is necessary to separate the fish harbor into two sides. One side is an existing fishing industry. The other side is made up of several pontoons for the marine sports equipment of the marine mooring. It is necessary to build facilities, such as the mooring facility, the storage facility, the repair-check facility, supply-cleaning facility, information booth, accommodations, education facility, and a marine culture exchange facility.

This experimental study aims to test the hypothesis that the occurrence of English sentence-final stop release is, at least, partly predictable by examining its phonetic context. 10 native(5 male and 5 female) speakers of American English recorded, in a sound-proof booth, sentences excerpted from novels and the natural documents on the World Wide Web. Based on the waveforms and spectrograms of the recorded sentences, judgements of the release of a sentence-final stop were made. If the aperiodic energy of a given final stop lasted more than .015 second, it was considered to be "released." The result reveals that English sentence-final stops tend to be released when they are 1) velar consonants, 2) preceeded by tense vowels, and 3) coda consonants of content words. The phonetic environment in which final stops are often released can be characterized by the articulatory comfortableness and the need for release burst noise, without which the final stops may not be correctly perceived. By examining the release of English final stops, it is concluded that the phonological events, which had been considered to occur rather "randomly," in fact, reflect the universal tendency of human speech: to minimize the speakers' and hearers' effort.
