This study was designed to assess food habits and fast food eating patterns of college students in Busan area. The subjects are 191 males and 149 females. The collected data were analyzed by SPSS package program. The summary of the results are follows : 1. The 83.3% of college students were used fast food in Busan area. Among them 77.6% are males and 90.3% are females and comparing their age, 88.1% of them were under 19 years old and 87.7% of students were living in their own house. 2. Utilized time to fast food chain, 44.7% are any time, 24.7% are evening time. There was statistical significance of difference by gender(p<0.01) and residence state(p<0.01) in fast food consumption pattern. 3. They expended 3,000 won most commonly and as their age and monthly expenditure increase, they spend more money for fast food. 4. 64.5% of the subjects selected menu depending on their food preferences, and 80.1% of females students selected favorable food at fast food restaurants. 5. The most popular fast food restaurant of college students was M, and tue gender (p<0.001), age (p<0.01) and residence status (p<0.001) affected significantly the preference of specific fast food restaurant.

This study was conducted to classify segmental group based on the factors of foodservice motivation and then conducted a survey for one month from July 15 to August 14, 2021 to analyze the influence of demographic characteristics, usage behavior, and motivation on eating out choice behavior. A total of 310 copies were used for empirical analysis. The result is as follows. First, males showed higher task type than females, and females showed higher number of change type, gastronomic type, and fit type. Second, in demographic characteristics, all groups showed strong motivation for foodservice in married people aged 31-40 and 41-50. Third, in the restaurant selecting behavior difference between the segmental groups according to the motivation for foodservice the most preferred menu was korean food for fit type, gourmet type, duty type and western food was the highest in the change type. Fourth, in the ordering method of difference in restaurant selecting behavior among segmental groups, all four groups showed higher order type than unlimited type or buffets type. The limitations of this study are limited to the food field and analysis should be done, but the results of the study on specific food items have not been obtained. Therefore, it is hoped that the future research will be conducted by designating specific food fields.

Corrugated webs have been used for composite prestressed concrete box girder bridges. Innovative steel plate girders using corrugated webs have been proposed. It has been found that analytical and experimental researches conducted to determine the strength of trapezoidally corrugated webs can fail with respect to three different buckling modes: local, global, and interactive shear buckling. Shear buckling capacity equations based on classical and orthotropic plate buckling theories have been proposed,but these equations show some differences. In this paper, geometric parameters that influence interactive shear buckling behavior with interaction effects are identified via extensive bifurcation buckling analysis using the finite element meth.

The maximum strength of the stainless steel square and the circular hollow section columns, which are cold-formed and TIG welded, is experimented on and analyzed. The paper presents centrally compressed experiments, including stub column tests and coupon tests, on stainless steel pipe columns. A total of 24 stainless steel pipe column experiments are conducted, using the slenderness ratios ($L_k/r$ = 20, 30, 40, 50, 60, 70) as parameters. The experimental results were compared with the design standard curves, AIK-LSD and AISC-LRFD, AIJ-LSD, SIJ-ASD curves, and multiple column curves.

As building structures become higher and longer-spanned these days, welding fabrication may become more and more difficult as the thickness of the plate increases. The use of high-strength steel is one of the solutions to reduce membrane thickness. Using high-strength steel would reduce the size of the column, which is under high axial load. Performance tests of high-strength box-type and H-shaped welded columns subjected to the combined bending and axial compressive load were carried out with variable axial load and slenderness ratio. Beam-column test results showed that the ultimate strength satisfied both ASD and LRFD codes

This study aims to examine the structure and meaning of the perception of rural amenity which rural and urban residents have. Many Lickert scaled questions measure how much important the respondents think about the various items related to rural amenity respectively. It reveals that there is not meaningful difference in the relative importance among three upper dimensions composing the construct of rural amenity, historic-cultural dimension, natural environmental dimension and living condition dimension. This means that our respondents are not willing to pursue historic-cultural aspects and natural environmental aspects at the risk of living condition being able to enjoy comfortable and affluent opportunities. And also, this results reveals that people might have a quite different perception compared with academic discourse putting much weight on historic-cultural dimension and natural environmental dimension.

Experiments and the parametric based on finite element model were conducted to investigate the behavior and strength of a gussettube connection concerned with eccentricity and selenderness ratio. Because of limitations in loading capacity the specimens were fabricated with 1/3 scale of full size. Of primary interest here are the ultimate strength of connections having eccentricity caused by lateral loads. As a result the effect of eccentricity on the buckling strength was examined and the validity of the finite element model adopted in this study was verified through comparing with test results.

본 연구는 미국 Utah주의 Logan시에 있는 유타주립대하(USU)Credit Union의 멤버들을 대상으로, 신용사용과 신용에 대한 태도가 그들의 경제적 만족도와 어느정도 관련이 있는지를 조사하였다. 연구는 1989년 3월에서 5월까지 걸쳐 USU Credit Union의 지원으로 이루어졌으며, 자료는 21세에서 65세까지의 멤버들 중 500명을 임의 추출하여 설문지 조사를 실시하여(설문지는 본 연구를 위한 문항과 Credit Union 멤버 Survey문항이 함께 이루어졌다) 그중 274명(54.8%)으 답변이 자료분석에 사용되었다. 대부분의 사람들은 집이나 차, 또는 교육비, 의료비에 신용을 사용하는데 긍정적 태도를 보였으며, 반수 이상의 사람들이 신용을 사용함으로써 수수료 또는 이자를 지불하고 있었다. 월평균 신용 납부액은 $643이였으며, 반수 이상의 응답자가 그들의 신용차입액에 대해 걱정하고 있는 반면, 4.4%의 응답자만이 신용을 사용하지 않고 있다고 대답했다. t-테스트, 변량분석, 그리고 상관관계 분석에 의해 경제적 만족도와 의미있는 관계를 가지고 있는 요인들이 단계별 다중 희귀분석에 이용되었는데, 그 결과 사람들의 신용부담액에 대한 근심도가 그 어느것보다도 경제적 만족도와 강하게 연관되어 있는 것으로 나타났다. 이는 과거의 조사들이 가정의 빚, 즉 신용부담액과 수입에 대한 비율로써 가정의 경제적 만족정도(financial well-being)를 측정해온 것에 반한 사실로서, 경제적 만족도는 개인의 주관적 측정인 신용부담액에 대한 근심도와 큰 관련이 있음을 보여주었다.

The physical factor having a great influence among components of making values of profit model in apartment houses is equilibrium change of house and this study suggests an alternative of remodelling. It sets profit models including model dividing household of large scale into that of small scale using value making factor of apartment house and spatial composition techniques and model integrating households of small scale and converting them into those of large scale and finds that its economy is good as over 'average', evaluative value of economy is reduced as discount rate increases and economy of remodelling is superior.

The buckling length of exterior beam-columns of the first floor in moment resisting steel frames with weak beams is uncertain when plastic hinges occur at the ends of weak beams due to seismic loads. The objective of this study is to investigate the buckling strength of concrete-filled tubular beam-columns and to suggest the reduced buckling length of them to apply to the beam-column design code. The exterior beam-columns are modelized with horizontal displacement restraint springs. Their strength and reduced buckling length are evaluated by numerical analysis.
