This study was conducted to investigate the performance times, CM position and CM speed, pole chord length and pole chord angle, whole body angular momentum(X axis), and grip width in pole vault event according to the event and phase; touch down, pole plant, take-off, maximum pole bending pole straight, pole release, peak height, and foot contact, pole contact, free flight. The pole vaulting of four male elite vaulters including six trial were filmed using two video digital cameras at 60 Hz at 56th national athletic match, and data were collected through the DLT method of three dimensional cinematography. In general the better jumper is, the longer the performance time is. And the greater CM speed is, and the better his transformation ability of CM horizontal speed into vertical speed is. As he uses a longer pole, his grip is higher, and it is a enough for him to rock back his body, so that he pulls and pushes the pole well keeping his hips close to. An greater maximum angular momentum and early positioning of the hips parallel to the bar makes his body far side of the bar and his bar clearance easier. Specially our national jumper needs to have more powerful braking force during foot contact phase, and take his body on the pole after maximum pole bending, and pull and push the pole strongly keeping his hips close to. Also he needs to have stronger muscular strength in order to control the longer pole and use the pole of proper tension more efficiently.

A MBES (multibeam echo sounder) survey around Yokji Island, Korea, was conducted to find an effective method for removing error data. Two post-processing software programs, PDS2000 (RESON) and HIPS (CARIS), were used to remove the error data using an interactive editing method and the CUBE algorithm filter. The post-processing with the PDS2000 and HIPS programs, using the interactive editing method, took 120 and 168 hours, respectively, and there was little difference in the seafloor images. The processing time of the PDS2000 and HIPS programs using the CUBE algorithm filter was 36 and 60 hours, respectively. Nevertheless, there was little difference in the seafloor images because of differences in the factor parameters in each of the post-processing programs. Therefore, post-processing using CUBE filtering can save time in data processing and provide consistent results, excluding the subjective decisions of the operator. This method is more effective than other methods for rejecting erroneous multibeam echo sounder data.

This study was initiated to study suitability of the apparel sizing systems that utilized in women's ready-to-wear market. To achieve this, the researchers surveyed 383 women from the ages of 18 through 59. The result of this study are followed. 1) The targeted age of the apparel brand does not always correspond with the purchaser's age. The subjects tend to prefer the brands targeting younger women than their age. The women who prefer the brand targeting younger women than their age were less satisfied with the jacket size available in Korean apparel market. They also took into consideration their body size. 2) The subjects who prefer the brands aimed for younger women were dissatisfied with fit at waist and hips. 3) The result of this study also shows that the more sizes are needed for short and tall women. The subjects pointed out that hips of the pants gave worst fit. 4) KS standard size designation system which listed body measurements bust-hips stature was not well known to the consumers.

The study aimed to analyze the functional differences in 3D virtual garment programs and compare body scan data with the corresponding 3D virtual models. We selected 3D virtual garment programs, formed virtual models in a representative size for high-school male cyclists, and analyzed them using the Design-X program. The results were as follows. In the 3D virtual garment programs, the anthropometric items for virtual model forming differed significantly from the standard anthropometric items suggested by Size Korea. Comparing the lower body scan data and virtual models formed by the 3D virtual garment programs, the biggest difference was in the shapes of the waist and hips, i.e., the flatness values of the waist and hips were different for each program in the cross-section view. In the lower body, a data-input-based program was needed for changing the exact measurement position of the waist circumference and hips' shape in detail. If a 3D virtual garment program provides functions for the virtual model's joint angle input and free motion transformation, it is expected to be widely used in the sportswear industry.

1969년에 발간된 API521 1st edition에서는 Flare Load 저감용으로 적용되는 HIPS (High Integrity Protection System)는 모두 Pressure Safety Valve의 고장확률보다 낮은 SIL 3 (Safety Integrity Level)등급을 적용할 것을 요구하고 있다. Flare Stack 저감용 HIPS는 주로 압축기 출력압력상승, Reboiler Steam 과다주입, 전력공급중단냉각펌프고장 등에 의한 Flare 발생을 예방하기 위한 기능을 가진 SIF (Safety Instrumented Function)로 구성된다. 하지만 2007년도 발간된 API521 5th edition에서는 LOPA (Layer Of Protection Analysis) 분석을 통해 Target SIL을 도출하는 것으로 요구사항을 변경했다. 이에 따라 이번 연구에서는 Flare Load에 가장 큰 영향을 미치는 시나리오 중 대표적인 시나리오를 대상으로 HAZOP(Hazard and Operability Study)과 LOPA분석을 실시해서 Target SIL이 어떻게 도출되는지를 연구했다. Flare Stack에서 Flare를 발생시키는 대표적인 시나리오들에 대해 LOPA분석을 실시한 결과 압축기 출력압력상승은 SIL 2, Reboiler Steam 과다주입은 SIL 3, 전력공급중단은 SIL 0, 냉각펌프고장은 SIL 0로 모두가 SIL 3 가 나오지는 않았다. SIF 설계 시 Target SIL을 만족시키는 것도 중요하지만 운전 시 SIL 등급이 계속 유지되게 하지 위해 인적오류, 시스템적 고장, 하드웨어고장 등에 의해 SIF 기능불능화가 되는 것을 예방하기 위한 기능안전관리시스템 (FSMS)를 적용하는 것도 중요하다.

This study proposes a prototype design method for pants suited to adult women with a difference of 27cm or more between the circumference of their waist and hip. The first pattern was modified around the hem, in the number of darts at the waist and in the slope of the front center. The second pattern was modified in the position of the waist darts and the length of the front and back darts. The third pattern showed side-line wrinkling, so the slope of the side-line and the number of darts were adjusted. Pants patterns for women with large hips can be calculated by inserting the difference between hip and waist circumference in the settings for the center front angle, center back angle, front side line angle, back side line angle, dart length, etc. This enables designers to draft pants patterns suited to the body shape of women with a difference in hip and waist circumference of 27cm or more.

Purpose: We report on the 10-year clinical hip function and radiologic outcomes of patients who underwent hip arthroplasty using a COREN stem. Materials and Methods: A consecutive series of 224 primary cementless hip arthroplasty implantations were performed using a COREN stem between 2009 and 2011; among these, evaluation of 128 hips was performed during a minimum follow-up period of 10 years. The mean age of patients was 65.4 years (range, 40-82 years) and the mean duration of follow-up was 10.8 years (range, 10-12 years). Evaluation of clinical hip function and radiologic implant outcomes was performed according to clinical score, thigh pain, and radiologic analysis. Results: Dramatic improvement of the mean Harris hip score (HHS) from 59.4 preoperatively to 93.5 was observed at the final follow-up (P≤0.01). Stable fixation was demonstrated for all implants with no change in position except for one case of Vancouver type B2 periprosthetic femur fracture. A radiolucent line (RLL) was observed in 16 hips (12.5%). Thigh pain was observed in only two hips (1.6%) at the final follow-up. There were no cases of osteolysis around the stem. The survival rate for the COREN stem was 97.7%. Conclusion: Good long-term survival with excellent clinical and radiological outcomes can be achieved using the COREN femoral stem regardless of Dorr type.

The purposes of this study are to examine the characters of the lower body shape in the middle aged women and to make slacks pattern on the base of four difference body shapes. The lower body shapes were classified into 4 types on the basis of their lateral view silhouettes. The slacks patterns were based on the lower body shape characters and resulted in followings. In “Type 1” of the right body shape with the standard protrusion of abdomen and hips, little difference from conventional patterns was seen in experiment pattern, in which the front waist girth was W/4+0.5㎝+0.5㎝+fold(2.5㎝) and the back waist girth W/4+0.5㎝-0.5㎝+dart(3.5㎝). The front hip girth was defined as H/4+2.0㎝+0.5㎝ and the back hip girth as H/4+2.0㎝-0.5㎝ due to its increased ease amount produced by abdominal fat deposition. In the experimental pattern of “Type 2” with prominent hips, the front and back differences of the waist girth and the hip girth and the hip girth were defined as 1.0㎝ and 2.0㎝ separately. Accordingly, the front waist girth was W/4+0.5㎝+1.0㎝+fold(2.0㎝), the back waist girth W/4+0.5㎝-0.1㎝+dart(6.5㎝), the front hip girth H/4+2.0㎝+1.0㎝ and the back hip girth H/4+2.0㎝-1.0㎝. In “Type 3” with the prominent abdomen and the flat hips, the front waist girth was set up as W/4+0.5㎝+0.5㎝+fold(4.5㎝) for the increased front fold amount and the back waist girth was W/4+0.5㎝+0.5㎝+dart(3.0㎝). The front hip girth was made as H/4+2.5㎝+0.5㎝ and the back hip girth H/4+2.5㎝-0.5㎝. In “Type 4” with prominent abdomen and hips, considered were ① the increased front fold amount due to the abdominal protrusion, ② the increased back dart amount and the decreased back dart length owing to the hips prominent and ③ the front and back differences of waist and hip girth for the lateral view silhouette. Therefore the front waist girth was defined as W/4+0.5㎝+2.0㎝+fold(5.0㎝), the back waist girth as W/4+0.5㎝-2.0㎝+dart(4.0㎝), the front hip girth as H/4+2.0㎝+1.0㎝ and the back hip girth as H/4+2.0㎝-1.0㎝. The sensory evaluation of appearance and comfort was appeared more suitable on the experiment pattern than on the conventional pattern.
