The objective of this field research is to determine consumer's fashion sense and provide helpful information to manufacturers when planning designs and merchandizing strategies. This study's purpose was to observe what was being worn, colors and tones. The method of research was fixed point observation using digital photos. The subjects of the research were female college students, 18-22 years old. The T-shirt has become the representative item for casual and comfortable wear by the female college students. Pants and blue jeans were worn more often than skirts as a lower garment. This shows that the students think about their activities when choosing a lower garment. The majority of these students chose clothing that functioned well for their school activities. Among students that wore skirts about half wore a functional knee length while the other half wore a more fashionable mini-skirt. These students appear to care about both fashion and function. Blue was especially popular, with 70.4% of all lower garments being blue. This effect makes the body look thinner and may be one reason why blue is so popular. White is a popular color as an upper garment. White upper garments are easily matched with any color, while blue upper garments coordinate well with similarly colored blue lower garments. The distribution of upper garment color is significantly influenced by the seasons. Blue jean tones were many and varied, while upper garments were mostly weak tones and bright tones of pale, light and soft.

Objective: To investigate the dental phenotypes and treatment modalities (Tx-Mod) in Korean patients with Parry-Romberg syndrome (PRS) using longitudinal data. Methods: The samples consisted of 10 PRS patients, who were treated and/or followed-up at Seoul National University Dental Hospital between 1998 and 2019. Using a novel PRS severity index based on the numbers of the atrophy-involved area and asymmetry-involved item, we classified them into mild (n = 3), moderate (n = 2), and severe (n = 5). Dental phenotypes, including congenitally missing tooth (Con-Missing-Tooth), microdontia, tooth with short root (Short-Root), tooth with dilacerated root, and delayed eruption/impacted tooth, were investigated along with Tx-Mod. Results: The side of occurrence of all dental phenotypes showed 100% concordance with the side of PRS involvement. The most two common dental phenotypes were Con-Missing-Tooth and Short-Root (n = 29 and n = 17 in six patients). The sums of the average number of Con-Missing-Tooth and Short-Root increased from mild PRS to moderate PRS and severe PRS cases (1.0, 6.0, and 6.2). In terms of Tx-Mod, growth observation due to mild atrophy, fixed orthodontic treatment, and grafting were used for mild PRS cases. Tx-Mod for moderate PRS cases involved growth observation for surgery due to an early age at the initial visit. For severe PRS cases, diverse Tx-Mod combinations including unilateral functional appliance, fixed orthodontic treatment, growth observation, grafting, and orthognathic surgery were used. Conclusions: The novel PRS severity index may be useful to provide primary data for individualized diagnosis and treatment planning for PRS patients.

As the population of preschooler increases with the increment of employed women today, the physical environment of day-care center is becoming an important factor for the preschooler as well as home environment. In order to create a suitable and desirable day-care environment for preschoolers, the using behavior of the preschoolers, who are the main users, needs to be applied to the spacial design. In this research, play preference area of Korea and United States which have different physical environments are analyzed. Child behavior observation analysis technique, interview with the teacher in charge, floor plan and furniture arrangement plan of the day-care centers and photography were performed for this research. The subjects were 63 preschoolers of 50 months old who are using Korean and American day-care centers and play of five minutes per preschooler was filmed for 3 days. Total 01 189 motion pictures were analyzed for this research. As a result, the physical environment, programs, preference area and finally the similarity and difference according to the gender were clarified for each countries' day-care center. The Korean preschoolers preferred the block area most, the second most favorite area being art for the younger class and language for older class. According to the gender, girls preferred language area while boys chose block area. On the other hand in American preschoolers' case, due to the large variety of play area, the play preference was distributed among various area except several high preference area. Based on this research, when designing indoor play area of day care centers, the area of block, language, and art which are popular play preferences should be considered firsthand, and gender preference is also needed to be thought of. These results may be used as an important data for planning the day care center play area in the future.

공원 이용행태는 주로 이용자 설문이나 행태 관찰을 통해 조사되어 왔다. 하지만 기존 방식들은 시간과 비용이 많이 소모되고, 응답자나 조사자의 주관에 취약하다는 한계를 갖는다. 이로 인해 개별 도시에서 활용할 수 있는 체계적이고 일관된 공원 이용 실태 조사기법이 부족한 실정이다. 이에 본 연구는 부산광역시 도시공원을 대상으로 공원 이용 조사를 위한 무인비행장치의 활용성을 파악해 보고자 한다. 특히 기존에 신뢰성과 타당성이 검증된 체계적 관찰 기법인 여가활동 관찰 기법(SOPARC)과 비교하여 본 기법의 유용성을 살펴본다. 연구결과, 무인비행장치를 이용한 관찰결과는 SOPARC의 결과와 매우 높은 상관성을 보였으며, 통계적으로 유의한 수준에서 차이가 없는 것으로 나타났다. 또한 두 기법 모두 높은 수준의 검사-재검사 신뢰도를 나타냈다. 무인비행장치를 활용한 방법은 기존 관찰기법들에 비해 넓은 지역을 관찰할 수 있고, 정밀한 이용자 수 조사 및 공간 시설 이용패턴 파악에 적합한 장점을 가진 반면, 자세한 이용자 정보를 파악하기 어렵고, 날씨 등 조사 여건의 제약이 많다는 한계를 보였다. 따라서 두 기법을 상호보완적으로 활용하는 것이 바람직할 것이다. 마지막으로 무인비행장치를 활용한 공원 이용 조사 시 유의할 사항들을 제안하였다.

Aluminum nitride (AlN) thin films were prepared by using nitrogen ion beam assisted reactive radio frequency (RF) magnetron sputtering on the glass substrates without intentional substrate heating. After deposition, the effect of nitrogen ion beam energy on the structural and optical properties of AlN films were investigated by x-ray diffraction (XRD), atomic force microscope (AFM) and UV-Vis. spectrophotometer, respectively. AlN films deposited with $N^+$ ion irradiation at 100 eV show the higher (002) peak intensity in XRD pattern than other films. It means that $N^+$ ion energy of 100 eV is the favorable condition for low temperature crystallization. AFM images also show that surface average roughness is increased from 1.5 to 9.6 nm with $N^+$ ion energy in this study. In an optical observation, AlN films which deposited by $N^+$ ion beam energy of 100 eV show the higher transmittance than that of the films prepared with the other $N^+$ ion beam conditions.

The spatial planning of the elderly care facility plans is analyzed using space syntax in terms of encouraging the social interaction of the residents in this study. First, through the visibility graph analysis, openness and accessibility of space is analysed. Second, the walking behavior of residents through agent analysis model is simulated. Third, the space planning methods for the elderly care facilities are proposed based on the results. The results are as follows. According to the visibility graph analysis, the main corridor has high visual openness and high accessibility. The visual openness and accessibility of the unit living room, where social interaction among residents is possible in each unit, is low. Space planning is needed to increase direct protection and observation of employees to the unit living room. The location of the nurse station that manages the entire floor needs to be located where the openness and accessibility is most high. The nursing station should have a high degree of connectivity to the entire space, so that any accidents can be managed and contact is accessible. Through the agent simulation the flow from the center to each unit space is highest in the corridor space and the inflow to the private rooms and the living room are similar. Therefore, it is necessary to plan the accessibility of the unit living room more for the natural inflow of residents.

$SnO_2$ thin films were prepared on the Si substrate by radio frequency (RF) magnetron sputtering and then surface of the films were irradiated with intense Ar ion beam to investigate the effect of Ar ion irradiation on the properties and hydrogen gas sensitivity of the films. From atomic force microscope observation, it is supposed that intense Ar bombardments promote rough surface and increase gas sensitivity of $SnO_2$ films for hydrogen gas. The films that Ar ion beam irradiated at 6 keV show the higher sensitivity than the films were irradiated at 3 keV and 9 keV. These results suggest that the $SnO_2$ thin films irradiated with optimized Ar ion beam are promising for practical high-performance hydrogen gas sensors.

Magnetic Resonance Imaging (MRI) scanner is the device to draw an image of conditions and the spread of various tissue in the body. It is used by making the patient into rounded superconductor and using high frequency which cause resonances. It uses superconduction magnet and high frequency that is non-ionizing radiation so can acquire biochemical, physical, and functional information of tissue. It is also very useful because it can scan tomography from many different angles to diagnose disease of a nervous system, the heart, and a skeletal structure. It also has advantages of that there is no risk of radiation exposure and the ability of observation on organizations such as brains, livers and the spinal cord of people. Since these features, the rate of use has been increased accordingly more considerations of the security are required when it plans. The weight of devices and the cover problem of the strong magnetic field which is occurred by magnetic resonance at the time of diagnosis can cause very important structure problems and architectural condition. That also the recent tendency which needs stronger equipment means that planning of the MRI unit should generally aim at purposing of the proximity for the device maintenance and up-grade and of further expansion. However there are not enough studies and data on the magnet resonance imaging in domestic hospitals. According to these reasons, this study has an object of indicating basic data on MRI unit plan standard and alternative proposals.
