As Incheon International Airport(IIA) is located in an island 50-km away from Seoul, various travel equipments for access are required. So far two connecting bridges are constructed funded by civilian funds. For the further bridge construction, the reduction of forecast traffic amount and the government subsidy for the civilian funds are big issues. Comparing the access traffics of IIA to those other competing airports, traffic conditions inside the airport are superior to other competing airports from the management point of view, as utilization conditions and equipment capacities are periodically monitored and evaluated to set up comprehensive countermeasures following constructing by stages. However, while the accessability to IIA is very important, as IIA is built on an island the conflicts between near-by developers and traffic facility operators make further bridge construction difficult. As improving the accessibility to an airport is not easy to achieve only by the IIA management's efforts, the central government level authorities should organize a committee with agencies concerned and analyze the characteristics of access traffic periodically to suggest reform measures for each organization concerned to implement appropriate undertakings at apt timing. For the future, central government's level empirical research on the airport accessibility for synthetic and systematic plan set-up is expected.

The purpose of this study is to present an appropriate approach to urban regeneration by analyzing Gwangju Metropolitan City. For the study, residential area of Asia Culture Complex was analyzed based on GIS. The areas concerned were categorized and looked into by their Situation based on the analysis of urban infrastructure state. However, as the architectural space within a city are limited, and accurate assessment of them is needed. The residential areas have the following characteristics. They become an aging and dilapidating residential and socially underprivileged-concentrated area. It is necessary to set up a direction for a future-oriented planning for the development of these areas. Along with a decreasing population, it is important to improve the urban architecture environment for the elderly in an aging society. The economic growth of a city if necessary for the future. Therefore, the criteria for the assessment is required. And the subsequent setting-up and planning of a future direction for a city is badly needed. After that, an accurate assessment of a city called for. City space allows for various interpretations. As the rich are getting richer and the poor are getting poorer, a wealth is concentrated on one district or an area.

This study investigates differences in intensity across the three different Korean obstruent types in terms of the RMS amplitude of both the entire section and the first 512 samples of the immediately following vowel in two positions. The results showed that for the utterance initial position the RMS amplitude of both the entire section and the first 512 samples of the vowel was greatest for fortis obstruents, intermediate for aspirated ones, and weakest for lenis ones, with a significant difference between each pair of them. For the intervocalic position, in contrast, the intensity of the entire vowel was greatest for fortis obstruents, intermediate for lenis ones, and weakest for aspirated ones, with no significant difference between the last two groups, whereas the intensity of the first 512 samples of the vowel was greatest for fortis obstruents, intermediate for lenis ones, and weakest for aspirated ones, with a significant difference between each pair of the three groups. This means that the intensity of the earlier part of the vowel functions as a discriminator of Korean obstruents. The positional difference is due to the different behavior of the lenis obstruents in the intervocalic position, such that the intensity build-up is already on its way with voice lead.

The growth characteristics of bainite at early stage in the fast quenched spheroidal graphite cast irons containing 0.06%Mn and 0.45%Mn during austempering process, was investigated with optical and scanning electron microscope. The following results regarding the effects of Mn and isothermal heat treatment on the morphological variation of bainitic ferrite were obtained. The morphology of bainite varies from acicular below 350$^{\circ}C$ to feather shape above 350$^{\circ}C$. The period of isothermal treatment also affects the shape of bainite at the fixed temperature. At 350$^{\circ}C$, bainite is bamboo leaf-like up to 200 secs of isothermal holding time and with further increasing time up to 300 secs, changes to a mixed structure consisting of both feather and bamboo leaf and, finally becomes all feather shape at 900 secs. The morphology of bainitic ferrite formed at early stage of 300$^{\circ}C$ isothermal treatment is similar to that of bainitic ferrite formed at 250$^{\circ}C$ or 350$^{\circ}C$ with unbranched, linear ferrite. However, bainitic ferrite divides into branches with increasing isothermal treatment, which occurs more fast at 400$^{\circ}C$ than at 350$^{\circ}C$. The difference in adding amount of Mn influences the morphology of bainitic ferrite in upper bainite. The bainitic ferrite with 0.45%Mn is observed to be more stable than that with 0.06%Mn, remaining unbranched for a longer period at the same temperature.

Background: Breast cancer (BC) is the most frequent malignancy among females and is a leading cause of death of middle-aged women. Herein, we evaluated baseline characteristics for BC patients and also compared these variables across ealry and late recurrence groups. Materials and Methods: Between 1995 to 2014, among female breast cancer patients referred to our oncology clinic, eighty-six were entered into our study. All had distant metastasis. Early recurrence was defined as initial recurrence within 5 years following curative surgery irrespective of site. Likewise, late recurrence was defined as initial recurrence after 5 years. No recurrence was defined for survivors to a complete minimum of 10 years follow-up. Significant prognostic factors associated with early or late recurrence were selected according to the Akaike Information Criterion. Results: The median follow-up was 9 years (range, 1-18 years). During follow-up period, 51 recurrences occurred (distant metastasis), 31 early and 20 late. According to the site of recurrence, there were 51 distant. In this follow-up period, 19 patients died. Compared with the early recurrence group, the no recurrence group had lower lymph node involvement and more p53 positive lesions but the late recurrence group had lower tumor size. In comparison to no recurrence, p53 (odds ratio [OR] 6.94, 95% CI 1.49-32.16) was a significant prognostic factor for early recurrence within 5 years. Conclusions: Tumor size, p53 and LN metastasis are the most important risk factors for distance recurrence especially in early recurrence and also between of them, p53 is significant prognostic factor for early recurrence.

This study is about women's veils from Chosen period housed in various museums and see how they reflect the escalating inequality between the two sexes based on Confucianism and its social ramifications including the strict rules that kept women from freely communicating or staying in same quarters with men from tender age. I first visited various museums to see what kind of veils they had in their collections and then looked at reproductions, museum catalogues, and other studies to get a better understanding of the designs, colors, and fabrics of the veils in each collection and came to following conclusions:. 1. I looked at 26 veils of 7 different sues both in person and in museum catalogues, and they included a Neouls,3 Myunsas, l2Jahngots,4 Chuneuis,1 Sahkgat 3Junmos, and 1 Garima. Various documents attest to the existence of one more style of veil,1. e. skirt-shaped veil, but there was no specimen of the type. 2. Museums had various types of veils for women, but most of them dated from late Chosun period. 3. Female veils in Chosun period had dearly-defined characteristics depending on their wearers. Each type had its own fabric color, and form, so one could tell the status of the wearer just by looking at it 4. The veils that I found at museums around the country had following characteristics: . Neoul was worn by high-class women and it covered up the face better than other types of veils. Myunsa was also caned Myunsapo, and it featured brilliant gold foils to mark the salted status of the wearer. Jahngot was originally a robe for both sexes but it turned into a type of veil for low-class females in late am period and there were more Jangots in museum collections than my other type of veils. Chuneui has various styles and it has a cotton lining so low-class women wore it to both cover the face and to stay worn Sahkgat was worn by low-class women for its convenience. Junmo was elaborately decorated and showy, and it was worn by courtesans. Garima was worn by courtesans or professional women in medicine, and unlike other type of veils, it showed the face of the wearer.

Background This analysis presents patient-reported outcomes of breast augmentation procedures performed in Singapore using an inframammary fold incision and the "5 Ps" best practice principles for breast augmentation. These data are the first of their kind in Southeast Asian patients. Methods Through a retrospective chart review, patients who underwent primary breast augmentation with anatomical form-stable silicone gel breast implants using an inframammary fold incision were followed for ${\geq}6$ months postoperatively. The BREAST-Q Augmentation Module (scores standardized to 0 [worst] - 100 [best]) and Patient and Observer Scar Assessment Scale (POSAS; 1 [normal skin] to 10 [worst scar imaginable]) were administered. Responses were summarized using descriptive statistics. Patient-reported events were collected. Results Twenty-two Southeast Asian patients (mean age, 35.1 years) completed ${\geq}1$ postoperative BREAST-Q and POSAS assessment and were assessed 11 months to 5.5 years postoperatively. The mean postoperative BREAST-Q satisfaction with breasts and psychosocial well-being scores were 69.2 and 84.0, respectively. The mean POSAS score for their overall opinion of the scar was 4.2; the mean scores for all scar characteristics ranged from 1.2 to 4.2. Over 90% of patients (20/22) said that they would recommend the procedure. Patient complaints following surgery included anisomastia (possibly pre-existing; n=2), sensory loss at the nipple (n=2) or around the nipple (n=3), scarring (n=4), and slight capsular contracture (n=1). No patients required reoperation. Conclusions Southeast Asian patients reported high long-term satisfaction scores on the BREAST-Q scale and with their scar characteristics following breast augmentation using an inframammary fold incision, and nearly all said they would recommend this procedure. No reoperations were necessary in patients assessed for up to 5.5 years postoperatively.

컴퓨터 애니메이션을 이용한 군중 장면은 영화나 게임에서 자주 등장한다. 군중의 보행동작을 생성하기 위해 기존의 기술들은 주로 군중의 각 개체들의 행동을 모델링하여 접근하였다. 하지만, 군중의 규모가 커질수록 모든 개체를 개별적으로 제어하기는 어려워진다. 따라서 대규모 군중의 경우 개체별로 행동을 모델링하기보다 집단별로 모델링하여 보다 직관적으로 군중을 제어할 수 있다. 본 논문에서는 집단의 경로 추적 행동을 시뮬레이션하기 위한 집단 역장 모델을 제안한다. 집단은 같은 목적, 즉 같은 경로를 따라 무리지어 행동하는 개체들의 모임으로 정의된다. 또한 집단의 무리짓는 행동은 정렬, 응집, 분리의 세 가지 특징으로 규정지을 수 있다. 집단 역장 모델을 통해 이러한 집단의 특징들을 보존하면서 개체 간의 충돌을 자연스럽게 회피할 수 있다. 제안한 기술을 통하여, 사용자는 나란히 늘어선 집단에서 동그랗게 뭉쳐진 집단까지 원하는 형태의 경로 추적 애니메이션을 생성할 수 있다.

기존의 교통영향평가 지침으로 규정된 사업 시행 전후의 교통흐름은 가로구간의 경우 교통량, V/C, 평균통행속도와 서비스수준, 교차로의 경우 서비스 수준 등의 교통류 분석지표에 의하여 분석되고 있다. 이러한 교통류 분석지표는 확률론적(stochastic)인 교통류의 특성을 효율적으로 번영하지 못하며, 특히 개별 가로구간과 교차로에 국한하여 분석됨으로서 사업 시행으로 인한 교통영향 분석 범위 전체 구간의 교통흐름을 종합적으로 분석하기에는 미흡하다. 본 연구는 차량추종모형(Car-Following Theory)에 의한 미시적 시뮬레이션(microscopic-simulation) 기법을 적용하여, 개별 구간과 교차로 분석 범위를 넘어서 사업 대상 교통영향 반경 내의 교통흐름을 가시적(visual)하게 보여줄 수 있는 방안과 이를 바탕으로 공간적 범위 설정 개선방안, 개선대책 수립에 따른 효과분석 방안 등 다양한 분석결과를 도출하였다.
