  • This study aimed to examine the cause and consequence of emotional labor strategies based on the emotional labor framework. To investigate the boundary condition of the current research model, the study proposed that job autonomy would moderate the effects of emotional labor on employees' well-being. To achieve the purpose of the study, it was first tested whether neuroticism and extroversion of employees predicted the focal outcomes (i.e., burnout and work engagement) via distinct emotional labor strategies. Second, the moderation effects of job autonomy were tested for each emotional labor strategy in predicting the focal outcomes. Third, the conditional indirect effects of job autonomy on the mediation process were examined. The results revealed that surface acting partially mediated the relationship between neuroticism and burnout, whereas deep acting fully mediated the relationship between extraversion and work engagement. Regarding the moderating effects of job autonomy, it significantly moderated the relationship between surface acting and burnout and between deep acting and work engagement. In addition, from the moderated mediation effects, the conditional indirect effects of job autonomy were significant. Finally, theoretical and practical implications are discussed and limitations and future research directions were suggested.

  • 본 논문은 기 수행된 1:5축소 10층 RC 공동주택의 지진모의 실험결과에 비추어 근래 개발된 PERFORM-3D를 이용하여 해석적 모사를 시도하였다. 해석과 실험의 상관관계 분석에 의해 다음과 같은 결론을 얻었다. (1) 재현주기 50년 지진에 대해 실험과 해석이 매우 유사한 탄성거동을 보였다. 반면 우리나라의 설계지진과 최대지진에 대해서는 비선형 거동을 보이긴 하지만 실험의 최대응답과 강성 및 강도 저하를 제대로 모사하지 못하였다. 이의 주된 이유는 슬라브 거동을 탄성으로 가정하였기 때문이라고 판단된다. (2) 탄성영역 거동에 대해 해석모델이 전체 거동을 비교적 잘 모사하는 반면, 벽체 상호간에 걸친 힘의 분포에 있어서 실험과 상당한 차이를 보여주었다. (3) 최대지진에서 벽체의 전단변형은 비교적 잘 모사한 반면 휨변형의 경우 10배정도 과장되었다. 이는 일부 해석모델에서 인방보를 무시한 결과로 추정된다.

  • This study investigated the influential range of landmarks and the relationship between landmarks and cognition factor so as to offer basic data to be used for the effective use and the management of landmarks. In this study, eighteen famous landmark in Seoul were selected and analyzed. The result of this study can be summarized as follows : 1) First, eighteen determining elements of cognition factors were selected via documents survey. Second, general cognition factors of landmarks were analysed using these elements through questionnaires to specialists. As a result of factor analysis, historic cultural factor, scale factor, visual form factor, locational factor and uniqueness factor were revealed. 2) According to revealed cognition factor, eighteen landmarks are categorized into four types using MDS method via questionnaire to resident in Seoul city. These four types of landmarks are: type I that are recognized by historic cultural factor; type II that are recognized by scale factor; type III that are recognized by uniqueness factor; and type IV that are recognized by visual form factor. 3) As the result of regression, the influential range of landmarks were revealed at about a 10km radius(type I : 12km type II : whole area of Seoul city≒15km, typeIII : 8.7km, typeIV : 8.5km). 4) As a result of analysing the correlation between the influential range and the cognition factor through multiple linear regression analysis, the locational factor is the main factor affecting the influential range of landmarks in every type. The uniqueness factor comes next, which affects influential range partially. 5) Except type 1, as a result of analysing the correlation between influential range and the physical heights of landmarks, a quadratic equation is revealed, showing that the influential range of landmarks over 200 meters in height shows a radical change. Landmarks can be used as reinforcement tools of legibility, effective tools for landscape management and for the improvement of a community's image. This study on the influential range of landmarks and main cognition factor can be utilized as a landmark management plan and in urban planning, such as a new town plan.

  • The purpose of this study was to develop a "Family Play Therapy Program" using puppets to decrease attachment problems for families with children having attachment problems and to examine its effectiveness. The participants were an experimental group of 16 individuals(8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers) and a control group of 16 individuals (8 children with attachment problems whose ages ranged from 4 to 5 and 8 mothers). The experimental group was treated through the Family Play Therapy Program, which involved the use of puppets and was held for twelve sessions twice a week. The changes in the participants were measured in order to examine the effects of the program. The researcher measured children's emotional and behavioral expression(TBP), the mothers' sense of self(Self-Differentiation Scale), personal relationships(ECR-R), and the perception of family functions(ICPS-FFS) both before and after the FPT program and compared their differences. The MIM Rating Scale and Marschak Behavior Rating Scale were administered to examine the interactions between mothers and children, and 1:1 interviews were also conducted. The data thus gathered were used for non-parametric analysis(Mann-Whitney U test and Wilcoxon rank sum test)using SPSS WIN 17.0. The results of this study were as follows: First, the program had a positive effect on children's emotional expression. After the problem were over, negative emotional and behavioral expression in the experimental group decreased. Second, the program had a positive effect on mothers' self-differentiation and personal relationships. Third, the program had a positive effect on changes in the interaction behaviors between the mother and child. Fourth, the program had a partially positive effect on the responses from their group developmental stages, especially on the subscale of both a program for the reinforcement of mothers' emotions and family play program utilizing puppets.

  • 기존의 층고절감형 합성보 시스템은 철골보의 웨브면에 바닥판을 삽입하여 시공하기 때문에 상대적으로 기존 합성보 형식과 비교하여 층고를 대폭적으로 줄일 수 있지만, 적용되는 철골보 춤이 제한되기 때문에 적용 가능한 스팬이 한정되어 있어 여러 가지 다양한 건축구조의 수요에 능동적으로 대처하기가 어려운 단점이 있다. 따라서, 본 연구에서는 기존의 층고절감형 합성보의 단점을 해결하기 위하여 합성보의 춤을 자유로이 조절할 수 있는 층고절감형 매입형 합성보를 개발하였다. 본 연구는 콘크리트에 매입된 강팡성형 철골보를 가지는 불완전 합성보의 휨거동에 관한 것이다. 총 5개의 실대형 실험체를 전단연결재 및 보강근의 사용유무, 슬래브 형식을 주요변수로 하여 실험을 수행하였다. 실험결과, 별도의 전단연결재를 설치하지 않은 실험체는 자체가 가지고 있는 기계적 화학적 부착응력으로 인해 $0.20{\sim}0.76N/mm^2$의 부착응력을 나타내었다.

  • In this paper, a study of stability and health of a newly-built railway tunnel is presented. The field test was implemented to monitor the secondary lining due to the significant cracking behaviors influenced the stability and health of the tunnel structure. Surface strain gauges were installed for monitoring the status of crack openings, and the monitoring outputs demonstrated that the cracks were still in the developing stage. Additionally, adjacent tunnel and poor condition of surrounding rock were identified as the causes of the lining cracking by systematically characterizing the crack spatial distribution, tunnel site and surrounding rock conditions. Reconstruction of partial lining and reconstruction of the whole secondary lining were designed as the maintenance projects for different cracking regions based on the construction feasibility. For assessing the health conditions of the reinforced lining, embedded strain gauges were set up to continuously measure the strain and the internal force of the reconstructed structures. For the partially reconstructed lining, the outputs show the maximum tensile elongation is 0.018 mm during 227 days, which means the structure has no obvious deformation after maintenance. The one-year monitoring of full-section was implemented in the other two completely reconstructed cross-sections by embedded strain gauge. The outputs show the reconstructed secondary lining has undertaken the pressure of surrounding rock with the time passing. According to the calculated compressive and tensile safety factors, the completely reconstructed lining has been in reliable and safe condition during the past year after reinforcement. It can conclude that the aforementioned maintenance projects can effectively ensure the stability and health of this tunnel.
