  • The object of this study lies on classifying the size, which is mostly favored in Korea where the wedding dress is usually regarded as an article for rent, and on suggesting the range of sleeve design and that of neck line of bodice. For that, I extracted the average size by analyzing and researching the standard size of actual bodice from real wedding dress manufacturing company. According to the result of the research I named the standard size of Korean wedding dress for rent as 'WM' which has the girth of 88cm and the waist measure of 69cm. Based on the size 'WM', I also named the size 'WS' which has the girth of 82cm with extra length of 6cm up and down and the waist measure of 64cm with extra length of 5cm, and the size 'WL' which has the girth of 94cm and the waist measure of 74cm with same extra length as the size 'WS'. The extra space for the inseam of the back is 3 inches for left and right for all sizes and the mark of body size is standardized as 'girth-waist measure'. After that, I suggested the design types of sleeves and neck line of bodice which defined as its size by classifying the bodice of wedding dress based on its size. Generally the neck line of the tank top style has the widest range of wearable size, and the high neck line and bateau neck line types have the narrowest range. And the sleeveless type has the widest range of wearable size while the raglan type has the narrowest one.

  • The borehole heat exchanger of Geothermal Heat Pump (GHP) system should be sustainable and cost effective for long term operation. To guaranty the performance of the system thermal Response Tests (TRTs) with simple recommended procedures have been applied in many countries. Korea government developed a standard TRT procedure in order to control the quality on GHP projects. In the TRT procedure interpretation method has a rule that data set has to be interpreted by the line source model(LSM). The LSM employes some assumptions that surrounding medium is homogeneous and the line source is infinite and constant heat flux, however real ground condition is unisotropic and heterogeneous, and showing regional or local ground water flows in many cases. We need to develope improved evaluation models to estimate accurate ground thermal conductivity with respect to geological and influence of ground water because current TRT standard test procedure has limitations to be applied for every locations and system. This study surveyed the uncertainty of the thermal parameters from the interpretation method considering different evaluation period. The interpretation of 208 TRT data sets represents limitations of LSM application that some obtained ground thermal conductivities are statistically unstable and convergence time of ground thermal conductivity over test period shows trends responding the length of test period. This evaluation study will be helpful to provide some effective procedure for the thermal parameter estimation and to complement current TRT standard procedure.

  • This paper presents the design considerations and analysis for an interleaved boundary conduction mode power factor correction buck converter. A thorough analysis of the harmonic content of the AC line current is presented to examine the allowable voltage gain (K value) for meeting the EN61000-3-2, Class D standard while maximizing efficiency. The results of the harmonic analysis are used to derive the required value of K and therefore the output voltage necessary to meet the class D requirements for a given AC line voltage. The discussed design consideration and harmonic current analysis are verified on a 300W universal line experimental prototype converter with an 80V output. The measured efficiencies remain above 96% down to 20% of the full load. The input current harmonics also meet the IEC61000-3-2 (class D) standard.

  • 본 논문은 영상의 손실 압축에 널리 사용되는 JPEG 표준을 확장하여 압축률을 향상시키기 위한 방법을 제안한다. 연속적인 신호를 압축하는데 널리 사용되는 증분 압축 기법을 보다 효과적으로 손실 영상 압축 방법에 적용하기 위하여 행이나 열단위로 예측(prediction)과 이산 코사인 변환을 수행하고 양자화, 엔트로프 부호화 등의 과정을 거쳐 영상을 압축하기 위한 방법을 제안한다. 특히 JPEG 표준과 행/열 단위 압축 방법의 장점을 동시에 갖게 하기 위해 JPEG 표준의 틀에서 선택적으로 블럭에 행/열 단위 압축을 수행함으로써 압축률을 향상시킨다. 실험 결과 본 논문에서 제안하는 압축 방법은 사용자가 압축 시 지정한 화질이 높을 경우 JPEG보다 높은 압축률을 나타내는 것을 확인할 수 있다. 따라서 본 논문에서 제안하는 압축 방법은 간단하게 기존의 JPEG 압축 방식에 추가되어 고화질의 영상을 효율적으로 압축하는데 사용될 수 있다.

  • Since the characteristic frequency is decreased in proportion to the fault distance, the characteristic frequency component may be insufficiently eliminated by a low-pass filter on a long transmission line. In order to set a standard for the cut-off frequency of the low-pass filter, this paper proposes a method for obtaining the characteristic frequencies due to line faults. The application results of the proposed method are presented for line to ground (LG) faults and line to line (LL) faults on a 345 kV 200 km overhead transmission line. The EMTP is used to generate fault signals under different fault locations and fault inception angles. By comparison between the characteristic frequencies obtained from the proposed method and the EMTP simulation, it is shown that the proposed method accurately obtains the characteristic frequency.

  • When operating Express and Standard trains, which run with two different scheduled time, in a single line with limited number of side tracks for overtaking standard trains, it is required to have various modeling methodologies and simulations in order to calculate an optimum headway to maximize the capacity of the line with the best scheduled time. Especially it is inevitable that following trains have to slow down or stop in the middle of their operations due to the preceding trains, in case it is inappropriate controlled about either in which station an overtaking should be taken or how long it should be. This study is to analyze TPS data which have been produced with a simulation program which the team has invented to optimize Express and Standard mixed traffic plan and to introduce an algorism which shows detected conflict data, calculates appropriate dwell time after getting overtaken and helps to decide stations for overtaking.

  • After 1th line was built in 1974, the history of subway in Korea has been expended to 9th line which is under construction. It is time to prepare nation wide subway grounding system urgently according to the domestic electric standard that aligns to world wide standard by WTO/TBT treat (1995). Newly added grounding system to the fundamentally different system caused many problems. PSD(platform screen door) and other newly added equipment are also need grounding system. By the electrical code(established by Korea Electric Association), low voltage equipment(including grounding system) under 1,000V AC are in the process of change into IEC 60374. IEC 60364 standard will be added to the electrical code(established by Korea Electric Association) in 2007 and amended and after 3-5 years later, it will become a complete IEC 60364. So the purpose of this study is to compare the domestic rail road grounding system and suggest the standardized grounding system for the newly built subway.
