The purpose of this study was to investigate the brand awareness, attributes and purchase behaviors for luxury products in the age of mcluxury. In-depth interviews were conducted to 18 consumers(10 singles, 8 married) in the age range of 20～49 and having purchased luxury products twice in last 1 year. The interviews were directed by a trained mediator according to the interview guidelines and recorded. Interviewees were asked to talk freely and protocols were made for data analysis. Similarities were found regarding the salient attributes, brand awareness of luxury products as known in general; however, the perceived importance of each attribute of luxury products seemed to be changed as mcLuxury has continued. Moreover, the consumers' attitudes toward the luxury products consumption tended to become favorable than before, and the motives to buy luxury products were more valueoriented and self fulfillment rather than display one's wealth. The buying behaviors of luxury products vary among different age groups. However, most of them tended to purchase luxury products at duty-free shops and premium outlets while traveling abroad, or bought them on sale at domestic department stores.

This study was conducted to investigate the effects of weight control programs on BMI, serum profiles, nutrition knowledge and eating behaviors of adult obese women. The subjects of this study were 33 adult obese women aged 30- 65 years residing in Seoul. The weight control program for obese women included nutritional education, cognitive behavioral therapy and exercise for 12 weeks. The weight control experience of the subjects was 60.6%. They preferred physical exercise and diet restriction to weight control and 72.7% of subjects answered that the reasons for wanting to control their weight was health. The BMI of test subjects significantly decreased (p<0.001) from 28.3 to 27.1 after the 12 weeks of the weight control program. In addition, the % body fat significantly decreased (p<0.001) from 36.4% to 34.5% after completion of the weight control program. SGPT levels in the serum were also significantly decreased (p<0.05) after the program. Triglyceride levels significantly decreased from 194.9 mg/dL to 98.1 mg/dL (p<0.01) and the HDL cholesterol level significantly increased (p<0.01) from 55.8 mg/dL to 60.0 mg/dL after completion of the weight control program. Nutritional knowledge and eating behavior scores were significantly increased (p<0.001). In addition, the eating self-efficacy of the subjects was significantly increased (p<0.01); however, the food diversity scores were not changed after the program. These results suggest that the weight control program for adult obese women may be effectively used to promote weight reduction and improve nutritional knowledge and eating behavior.

폴리이미드는 유리상 고분자로서 높은 화학적 저항성과 열적 안정성을 지니고 있으며, 기계적 물성이 거의 변하지 않는다. 본 연구에서는 황화수소와 메탄의 투과특성을 알아보기 위하여 폴리이미드 중공사막을 건/습식 상전이 공정에 의하여 제조하였고, 제조된 중공사막의 구조 및 실리콘 코팅 전/후의 황화수소와 메탄의 투과특성에 대하여 알아보았다. 압력이 증가함에 따라 황화수소의 투과도는 가소화 현상으로 인해 증가하였고, 황화수소와 메탄의 선택도 역시 증가하는 것으로 나타났다. 실험에 사용된 세 종류의 막 가운데 KSM03b의 투과도와 KSM03d의 선택도가 가장 높은 것으로 나타났다. air gap이 증가 할수록 투과도는 감소하지만 선택도는 증가하였다. 또한 실리콘 코팅 후 투과도는 감소하였지만, 선택도는 증가하였고 7기압에서 KSM03d의 선택도는 275이었다.

Fe based (FeCSiBPCrMoAl) amorphous powder, which is a composition of iron blast cast slag, were produced by a gas atomization process, and sequently mixed with ductile Cu powder by a mechanical ball milling process. The Fe-based amorphous powders and the Fe-Cu composite powders were compacted by a spark plasma sintering (SPS) process. Densification of the Fe amorphous-Cu composited powders by spark plasma sintering of was occurred through a plastic deformation of the each amorphous powder and Cu phase. The SPS samples milled by AGO-2 under 500 rpm had the best homogeneity of Cu phase and showed the smallest Cu pool size. Micro-Vickers hardness of the as-SPSed specimens was changed with the milling processes.

This paper reviewed the relationship between boundary spanning behaviors and service quality, and the moderating effect of gender. Based on the responses from 204 employees in outdoor-food franchising system, hierarchical regression analysis showed that service delivery has positive relationships with all service quality factors, and external representation and internal influence have partly positive relationship with them. Gender appeared to have partly moderating effect on the relationship between only internal influence and service quality.

The changes of feeding pattern and the amount of insecticide penetrated into the leaf were monitored for 420 min after treatment of three concentrations of dinotefuran. At about 30 min after treatment of insecticide, the overall feeding pattern in EPG (Electrical Penetration Graph) monitoring was started to change, and there was significant difference in proportions of NP (non-penetration), PA (pathway activity), and phloem-feeding patterns among the different concentrations of dinotefuran treatment. Especially, as the amount of insecticide penetrated into a leaf increased, the reactive behaviors against this insecticide such as withdrawal of proboscis and movements of stylet of aphid were more quickly exhibited. And also, total time at which the proboscis of the aphids did not penetrate the plant was getting longer. The amount of dinotefuran penetrated into a leaf was monitored with HPLC. When the recommended concentration (100 ㎎/L) of the insecticide was treated, 5.24~7.24 ㎎/L of the insecticide was detected from the leaf, and the proboscis of the aphids was apparently withdrawn from the leaf at approximately 60 minutes after treatment of this insecticide.

Movement behaviors of specimens of mite (Tetranychus urticae) were computationally analyzed after the treatments of pesticide, abamectin, at a low concentration of 0.78ppb. During the observation period, test specimens were placed individually on the bean leaves (diameter=7mm), and their position was recorded in 2-dimension at 0.25 second intervals (8 hours before treatment and 8 hours after treatment). The selected parameters such as speed, angular change, meander, etc, were checked for characterizing response behaviors after the treatments. The difference of mite behavior was accordingly observed after the treatments, and the time spent in the center area appeared to be longer after the treatments. Additional characterization of movement behaviors was computationally checked, and utilization of behavioral monitoring in pest management was further discussed regarding early detection of susceptible or resistant strains.

In this work, the hydrogen storage behaviors of carbon nanotubes (CNTs)/metal-organic frameworks-5 (MOF-5) hybrid composites (CNTs/MOF-5) were studied. Hydrothermal synthesis of MOF-5 was conducted by conventional convection heating using 1-methyl-2-pyrrolidone (NMP) as a solvent. Morphological characteristics and average size of the CNTs/MOF-5 were also obtained using a scanning electron microscopy (SEM). The pore structure and specific surface area of the CNTs/MOF-5 were analyzed by N2/77 K adsorption isotherms. The capacity of hydrogen storage of the CNTs/MOF-5 was investigated at 298 K/100 bar. As a result, the CNTs/MOF-5 had crystalline structures which were formed by hybrid synthesis process. It was noted that the CNTs/MOF-5 can be potentially encouraging materials for hydrogen adsorption and storage applications at room temperature.

Behaviors of saturated fatty acid halides (CI4, C16, C18) were measured by LB method when the molecules were stimulated by pressure. The saturated fatty acid halides were deposited on the indium tin oxide(lTO) glass by the LB method. The average organic ultra thin film size and the surface roughness of the fatty acid halides thin films were investigated using AFM. It was found that AFM images show small surface roughness (2.5~5.0 nm) and the organic ultra thin film size of 2.5~12 nm. Both aggregations and pin-holes were also seen on the AFM images. However we found that the surface roughness. These effects seem to be reasonable to be related to the increase of the organic ultra thin film size of fatty acid halides.

목적 : 자폐아동의 상동행동 감소를 위한 중재방법으로 조건부 운동방법을 통한 응용행동분석과 감각통합치료의 효과를 비교하고자 한다.연구방법 : 본 연구는 개별실험 연구 설계인 교차중재설계(alternating treatment design)방법을 사용하여 응용행동분석의 조건부 운동방법과 감각통합치료를 상호 교차해서 상동행동을 치료 하였다. 연구대상은 중증 정신지체와 자폐증상을 갖고 정신지체아동 시설에서 생활하는 만 8세 10개월 된 남아였다. 상동행동 감소를 위한 중재방법으로 1회기에 20분씩 감각통합 치료와 조건부 운동 방법을 교차하면서 각 5회씩 실시하였다. 상동행동은 시각적 상동행동과 손가락 상동행동으로 나누어 측정하였다. 종속변인의 측정은 페그를 끼우는 과제수행 과정 중에 발생하는 상동행동을 비디오로 촬영한 후, 등간 기록법(interval recording)으로 기초선 2회, 교차중재과정 10회, 일반화과정 1회 실시하였다.결과 : 치료 전에는 시각적 상동행동이 10분에 평균 21회(4～40회) 발생했으나 중재 후에는 감각통합 치료 후에 평균 1회(0～3회), 조건부 운동 후에는 평균 1.6회(0～10회)로 감소했고, 손가락 상동행동은 치료 전에는 평균 28회(10～36회), 감각통합치료 후에는 평균 3.5회(0～12회), 조건부 운동 후에는 평균 5.7회(0～16회)로 감소하였다. 치료 종료 3주 후에 상동행동을 10분간 페그를 끼우는 상태에서 1회 측정했을 때, 시각적 상동행동이 4～10회, 손가락 상동행동이 4～6회 발생한 것으로 보아 상동행동 치료효과가 적절히 유지된 것으로 보인다.결론 : 상동행동 감소를 위해 사용된 감각통합치료와 조건부 운동 방법을 통한 응용행동분석 모두 효과가 높은 것으로 나타났지만, 이 두 방법의 치료효과 비교에서는 현저한 가시적 차이를 보이지는 않았다.

교통사고의 여러 요인 중 대부분의 사고가 운전자의 특성과 운전행태가 교통사고에 가장 큰 영향을 미치고 있음을 2006년 경찰청 사고건수 자료를 통하여 파악할 수 있다. 현재 교통사고 감소 및 안전운전에 대한 사회적 요구에 부응하기 위하여 디지털 주행기록계, 차량용 블랙박스 등이 출시되고 있다. 주행기록계, 차량용 블랙박스 등은 사고 후 차량의 주행데이터를 이용하여 사고발생 원인에 대한 명확한 해석이 가능하다. 그러나 사고를 미연에 방지해 줄 수 있는 시스템은 현재 개발되지 못하고 있는 것이 사실이다. 본 연구는 실험차량을 이용하여 디지털 주행기록계, 차량용 블랙박스 등의 안전운전관리 시스템의 업그레이드가 가능할 뿐만 아니라, 운전자의 위험운전 정도를 분석할 수 있는 임계값을 개발하였다. 개발된 임계값을 이용하여 운전자의 안전운전 습성을 도모하고 안전운전 관리업무를 체계화하는데 기여할 수 있을 것이다.

In this study, the stress-strain response and the cracking behaviors of ITO film on a PET substrate are investigated. The cracking behaviors of ITO thin films deposited on a thermoplastic semi-crystalline polymer developed for flexible display applications was investigated by means of tensile experiments equipped with an electrical measurement apparatus and an in-situ optical microscope. Electrical resistance increased gradually in the elastic-to-plastic transition region of the stress strain curves and cracks formed. Numerous cracks were found in this region, and the increase of the resistance was linked to the cracking of ITO thin films. Upon loading, the initial cracks perpendicular to the tensile axis were observed at about 1% of the total strain. They propagated to the entire sample width as the strain increased. The spacing between the horizontal cracks is thought to be determined by the fracture strength and the thickness of the ITO film as well as by the interfacial strength between the ITO and PET. The effect of the strain rate on the cracking behavior was also investigated. The crack density increased as the strain increased. The spacing between the horizontal cracks (perpendicular to the stress axis) increased as the strain rate decreased. The increase of the crack density as the strain rate decreased can be attributed to the higher fraction of the plastic strain to the total strain at a given total strain. The higher critical strain for the onset of the increase in the resistance and the crack initiation of the ITO/PET with a thinner ITO film (300 ohms/sq.) suggests a higher strength of the thinner ITO film.

After treatment with imidacloprid, there were clear differences in the time to the first reaction of Myzus persicae among the concentrations treated. The time taken for the proboscis of the aphids to penetrate, during the recording plants increased as the imidacloprid concentration increased. Imidacloprid concentration inflow into a leaf was investigated using high-performance liquid chromatography, and the residues of the imidacloprid varied slightly with the different concentrations treated. However, the inflow rates of this insecticide into a leaf increased as the dipping times increased. Furthermore, it was shown that there was no relationship in inflow concentration between the concentrations and times of treatment. However, the concentration in the leaf differed according to the dipping time. Judging from the fact that the first reaction behavior against imidacloprid displayed at an inflow concentration of 0.32-0.35 ㎎/L, we concluded that inflow concentrations causing the first reaction of the aphids to the insecticide were much lower than the concentration treated. The general feeding characteristics of the aphids indicated that xylem and/or phloem feeding behavior continued after a series of probing behaviors and stylet activity during the first 3 h from the start of EPG recording. After 90 min treatment with imidacloprid, feeding behavior over the next 30 min indicated a significant increase in the withdrawal of the stylet from the plant at all treated concentrations. Xylem and/or phloem feeding patterns were significantly decreased during this time. In particular, the proportion of xylem feeding differed according to the concentration of imidacloprid.

The Manchester Driver Behavior Questionnaire (DBQ) is the most commonly used frameworks for investigating the relationship between self-reported driving behavior and accident involvement. After Reason et al. introduced DBQ, there were many studies replicating the research of Reason et al. in many countries. There was, however, no study replication of the Reason's research in Korea. The aim of this study is to replicate the distinction among errors, lapses and violations, and to evaluate the relationship of these behaviors with road traffic accidents on Korean drivers. 223 Korean drivers completed the Korean version of original DBQ with questions regarding background information, such as age, gender, annual mileage and accident involvement. Participants answered self-assessment questions, also. Factor analysis revealed three factors like Reason et al. The three factors were dangerous errors, violations and relatively harmless errors.
