This paper presents the approach involving fault detection and diagnosis of gears using pattern recognition and Wavelet transform. It describes result of the comparison between KDI (Kullback Discrimination Information) with the nearest neighbor classification rule as one of pattern recognition methods and Wavelet transform to know a way to detect and diagnosis of gear damages experimentally. To model the damages 1) Normal (no defect), 2) one tooth is worn out, 3) All teeth faces are worn out 4) One tooth is broken. The vibration sensor was attached on the bearing housing. This produced the total time history data that is 20 pieces of each condition. We chose the standard data and measure distance between standard and tested data. In Wavelet transform analysis method, the time series data of magnitude in specified frequency (rotary and mesh frequency) were earned. As a result, the monitoring system using Wavelet transform method and KDI with nearest neighbor classification rule successfully detected and classified the damages from the experimental data.

The four taboos in using Baekhotang as explained by Odang(吳瑭), are identical to the standard symptoms of Severe Exterior Heat Syndrome[表熱重證]. There are similarities between Sanghan and Onbyeong in using Baekhotang(白虎湯). But there are significant differences between Sanghan and Onbyeong in explaining the pathogenesis of human body. In pattern identification by the Wi-Gi-Yoeng-Hyeol(衛氣營血) system, body fluid[津液] is the key feature, whereas in that of the Yuk-Gyeong(六經) system, Yanggi(陽氣) is the point. Therefore, we can understand that the standard symptoms of pattern identification are slightly different. However, that Sanghan and Onbyeong present different explanations does not mean that the disease itself strictly 'belong' to one category. They are different approaches, not explanations for two different subjects. Therefore, Sanghan and Onbyeong should be studied in line with this concept.

단순한 사각주형(四角柱型) 물체(物體)에 대한 3차원 표준곡선을 해석하였다. 이들 표준곡선은 쌍극자배치(雙極子配置)에 대하여 적분방정식을(積分方程式) 이용한 수치계산기술(數値計算技術)로 구하였다. 전도성(電導性) 물체에 대한 IP응답(應答)은 물체의 폭과 두께의 비율에 따라서 그 패턴이 달라진다. 주향(走向)길이가 쌍극자간격(雙極子間隔)의 6배 이상이 되면 2차원의 결과와 유사하다. 또한 주향(走向)길이가 길고, 폭이 쌍극자 간격의 4배이상이 되면 층구조(層構造)(1차원) 해석도 가능하게 된다. 한편, 측선(測線)이 주향방향(走向方向)을 따라서 물체의 중심으로부터 멀어지는 효과는 물체의 깊이가 지표로부터 깊어질 때와 비슷하게 나타난다. 물체가 측선하(測線下)에서 측선과 평행(平行)한 방향으로 이동하더라도 IP패턴에는 거의 영향을 미치지 않는다.

The purpose of this study was to introduce the differential standard of the types of Angelicae Pubescentis Radix. We established the classificatory standard according to the external and internal morphology and the physicochemistrical pattern for the four types of Aucklandiae Radix. The results follow: 1. At the external shape, Angelica pubescens f. biserrata has rising lenticel and dark brown surface, Its section is light gray and its xylem is yellow gray. Aralia continentalis has big stem mark in upper portion, its section has no dense tissue with yellow gray. Heracleum hemsleyanum has dark brown surface and little lenticel, its cortical layer is white yellow and xylem is isabella and powdered. 2. At the internal shape, Angelica pubescens f. biserrata has phloem with half of the root and rare vessel. Aralia continentalis has phloem with two-thirds of the root and it has broad cutting and putting vessel that formed 1-2 row. Heracleum hemsleyanum also has phloem with half of the root and wide scattered latex tube and many large vessel. 3. At the TLC pattern, Heracleum hemsleyanum has remarkable dark spot at $R_{f}$ 0.23 on the sulphuric acid color pattern test, but others have faint. 4. At the HPLC pattern, all samples have generally patterns. But Angelica pubescens f. biserrata shows diminutive continentalic acid content and the peak at Rt 20.278min comes out on Heracleum hemsleyanum, but do not come out on Aralia continentalis and Angelica pubescens f. biserrata. Heracleum hemsleyanum has remarkable peak at Rt 20.278min, but shows no peak at Rt 29.023min unlike Aralia continentalis or Angelica pubescens f. biserrata. Also Aralia continentalis and Angelica pubescens f. biserrata show one remarkable peak at Rt 29.023, but Heracleum hemsleyanum do not show. Consequently, Aralia continentalis and Angelica pubescens f. biserrata are comparable whit continentalic acid content and Heracleum hemsleyanum is comparable with the peak at Rt 20.273 and Rt 29.023. So it is thought that content of continentalic acid and the peaks at Rt 20.278 and Rt 29.023 can apply to differentiate a species from other. It is considered the results of this study will be furnished the basis to succeeding studies and it is needed to extensive comparative study for the same genus-degree of relatedness.

This study is based on anthropometric data from the 7th Size Korea, we selected five subjects with measurements similar to average women in their twenties. The subjects participated in adaptability assessments and appearance assessments of skinny jeans produced by 8 selected brands, to identify the pattern and measurements characteristics of jeans assessed to be superior in appearance and movement adaptability. The results of this study were as follows. First, according to the results of appearance assessment made by the specialist group, B brand earned the highest assessment in response to questions regarding if 'there is an appropriate amount of ease in the crotch area' on the front side and 'an appropriate amount of ease in the hip circumference area' on the back side. Based on the above results, Synthesizing the survey results and the appearance assessment and movement adaptability assessment results, we suggest that when drafting the pattern for the standard size of waist measurement 27 inches (67cm), the hip circumference should be given an appropriate amount of ease, of around -6.6cm (-7.2%). The thigh circumference should be set with an appropriate amount of ease, which is -5.3cm (-9.4%).

This study aimed to suggest a simple and well-fitting flat pattern drafting method for a men's jacket. Four jackets in thick muslin were made from four different drafting methods utilizing a few measures as breast girth, center back length, and chest width, which were not much different from the drafting methods of woman's jacket. The appearance of the 4 jackets was evaluated by a pool of evaluators consisted of graduate students who had much clothing construction teaching experiences and their motion adaptability was evaluated by two wearers who belonged within the range of the average measures of the Korean male figure as reported from the 1997's Census for Standard Body Measure. A drafting method evaluated as the most well-fitting and well-functioning in general was chosen and modified to enhance the appearance and was reevaluated to confirm its fit improvement. As a result of this study, a new drafting method, simple and not much different from that of a woman's jacket pattern drafting method is proposed. Since this method is based on the minimal measures and ratios thereof, and is not as complicated as ordinary drafting methods for men's wear, the researcher expects that this drafting method allows more chances for the students to learn and understand men's wear more easily and comfortably.

In order to identify the origin and nature of the spilled oil in the potential source, we analyzed the pattern of alkyi PAM(Polynuclear Aromatic Hydrocarbons) in fuel standard and environmental samples. Alkyl PAM patterns are used for fuel-type identification in weathered environmental samples. Detection of alkyl PAH was achieved by operation CC/MS in the SIM mode. We chose ions of naphthalene(m/z 128), C1-naphthalene(m/z 142), C2-naphthalene(m/z 156), C3-naphthalene(m/z 170), C4-naphthalene(m/z 184) for the comparison of this pattern according to the type of fuel. We analyzed tile pattern of alkyl PAH in neat gasoline, kerosene, diesel, and JP-8, and in groundwater samples which were collected in monitoring wells. The distribution map of alkyl-naphthalene shows different patterns among four different fuel types (gasoline, kerosene, diesel, and JP-8). Particularly, tile distribution map of kerosene and JP-8 is found to be of value in identifying fuel type in that the difference is clear. Therefore distribution patterns of alkyl-PAH compounds provide another useful tool for fuel-type identification of petroleum fuels.

This study developed basic pattern for competition figure skating wear for school girls. Figure skating wears are difficult for making basic patterns based on standard size chart, because girls' body size are slimmer and more slender compared to the general girl's and the competition wears such as, swim suit with sleeves are, closely in contact with the player's body. The competition wears for school girl was made with consideration of changing of the body shape, physical exercises, and various specificities according to stretch material. To raise artistic effect while doing beautiful motions, and to assist in facile technique motions, competition wears need to have enough ease on the side line from waist to armpit, from armpit to wrist, and in trunk girth including crotch girth. Also, to stand out in beauty, a costume designing has a proper skirt position, length, flare width, and a tight bodice according to the player's body proportion. Most of the customers are displeased at the high price, unfitness of size, insufficient design, and difficulty in access, since they are not sold in sporting goods store. Therefore, a competition wear's basic pattern was made through scientific and emotional process including concerns on material properties, room for activities, and ideal body proportion. Systemizing the basic patterns of production method will solve high repairing expenses, unsuitable sizing, and improve accessibility for purchase.
