  • 본 연구는 최근 노동시장의 특정인 임시 일용직 증가의 원인을 분석하였다. 임시 일용직 증가 원인으로 기업의 수익성, 시장 변동성, 근로자의 자질에 대한 불확실성 측면에서 살펴보았다. 결과에 따르면 제조업의 경우 기업의 수익성과 건설업과 도소매업은 상품수요의 변동성과 관련이 깊은 것으로 나타났다. 한편 1990년대 이후 증가한 교육의 양적 팽창이 질적 향상을 수반하지 못한 결과 근로자의 자질에 대한 불확실성을 증가시키면서 기업은 상용직보다 임시 일용직을 선호하게 되었을 가능성도 간접적으로 확인되었다.

  • This study was designed to observe the marginal leakage of three permanent cements affected by three temporary cements. The temporary cements used in this study were Zinc oxide-eugenol, Non-eugenol, and Calcium hydroxide cements and the permanent cements were Zinc phosphate, Polycarboxylate and Alumina reinforced EBA cements. To measure the dye penetration into permanently cemented zone, the experimental specimens were treated with the temporary cements for a week. An analysis of the data obtained from 120 specimens resulted in the following conclusions: 1. Regardless of the types of the permanent cements used, using Calcium hydroxide cement as temporary cement showed higher marginal leakage than other temporary cements. 2. Using Polycarboxylate cement as permanent cement showed less marginal leakage than other permanent cements. 3. The marginal leakage in zinc phosphate cement was similar to Alumina reinforced EBA cement regardless of the types of the temporary cements.

  • The use of temporary container classrooms has increased in recent years due to the development of the construction industry and renovation or rehabilitation of schools. Therefore, various problems, such as errors during assembling, design and insulation issues, and noise problems, have surfaced during the construction of temporary container classrooms. This study analyzes the causes of assembly errors during the manufacturing and installation processes to improve the quality of temporary container classrooms. Assembly errors are caused by non-level planes and inaccurate cutting during the manufacturing process. In the installation process, poor leveling is a major factor that causes errors during the assembly of temporary container classrooms. These causes result in uneven horizontal or vertical planes and uneven height. To solve these problems, quality improvement measures, such as pin connection, jig, joint coupling, and surface plates are proposed in this study.

  • The entire construction safety is significantly influenced by proper uses of temporary structures. However, in current practices, temporary structures are used without sufficient planning and analysis on their impact on safety. Consequently, problems in worker safety and loss of productivity are frequently caused related to temporary structures. This paper introduces an approach that uses Building Information Modeling (BIM) to automatically create temporary structures as part of construction plans and identifies potential safety hazards related to the temporary structures. In this study, the type of temporary structure is limited to scaffolding. Automation algorithms were developed and applied to (1) analyze daily construction site conditions (2) create required scaffolding objects, and (3) identify potential safety hazards related to scaffolding. A case study using a real-world construction project demonstrated that scaffolding objects were properly created based on user-input and potential safety hazards were successfully identified without human intervention.

  • Background and Objectives : Temporary vocal fold injection is not only performed to restore the laryngeal function in temporary unilateral vocal fold paralysis or paresis, but also performed as a test injection prior to the permanent injection. Gelfoam has been safely used for the past several decades for the temporary vocal fold augmentation. Recently, we found a new material, called Radieses Lite, may be used as a temporary injection material. Material and Methods : We report preliminary results of 11 patients who had Radiesse Lite injection with a variety of pathologies. Results : Based on the results from the 6 patients who completed follow-up, the duration of effectiveness of Radiesse Lite seems to be from 2 to 3 months depending on the injection amount. Radiesse Lite satisfies several requirements of the ideal temporary vocal fold injection material in terms of injectability, convenience, duration of effectiveness and safety. Conclusion : The authors concluded that Radiesse Lite might be a good option for temporary vocal fold injection especially in the office setting.

  • 강교량 가설공사의 설계는 그동안 과거유사사업의 자료를 토대로 설계자의 경험에 의존하여 진행되어 왔다. 이로 인해 실제 현장에서 소요되는 가벤트에 대하여 과대설계 논란이 있으며, 시공단계에 불필요한 설계변경을 야기하고 있다. 본 연구에서는 강교의 설계작업 과정에서 생성되는 설계 자료와 가설공사의 수행에 필요한 자원에 대한 데이터베이스를 구축하여 강교 설치 가설공사의 최적화설계 지원 시스템을 개발하였다. 이를 통하여 가설시설물에 대한 설계를 최적화하며, 설계변경을 줄이는 데에 기여할 뿐만 아니라 설계정보를 시공단계에 활용하게 함으로써 업무의 효율성과 정확성을 제고하였다.

  • 국내에서도 홍수, 지진, 산사태, 화재 등의 다양한 재난재해로 인하여 이재민이 발생하고 있으며, 이 중 대다수가 이재민 임시주거시설로 대피하고 있다. 그러나 이재민 임시주거시설 내에서 개인공간을 확보할 수 있는 실내 임시주거시설의 배치와 성능에 관한 계획은 미비하다. 이에 이재민 임시주거시설 내 거주환경을 개선하기 위하여, 국민안전처에서 지정한 1인당 최소 수용면적 $3.3m^2$로 실내 임시주거시설의 모듈을 구축, 모듈의 배치계획을 진행하였으며, 실내 임시주거시설의 형태, 재료, 성능에 대한 평가 방향을 제시하였다.

  • Purpose - To understand the growing interests in the professional temporary workforce, this study aimed to examine the different types of professional temporary workers and their different effects on creative performance. Design/methodology/approach - By sub-classifying professional temporary workers as boundaryless workers and transitional workers, this study developed propositions to provide comprehensive framework for directing meaningful topics for future research on professional temporary workers. Findings - This study suggested that two types of professional temporary workers may differ significantly in terms of their work efforts for getting approval or acceptance from the team members and for achieving creative contributions in teams. Specifically, drawing on expectance theory, social identity theory and resource-based theory, this study discussed the relationship between acceptance(task-oriented vs. relational-oriented acceptance), employment duration(short-term status vs. long-term status), contract security(volition being temporary worker) and creative performance for boundaryless workers versus transitional workers. Research implications or Originality - This study have implications for increasing our understanding of professional temporary workers by showing that creative performance may vary by employment types.

  • Temporary occlusion of the parent artery or feeding artery is an useful method in microsurgery for cerebrovascular diseases. The advantages of the temporary clipping for intracranial aneurysm surgery have already been proven by many experimental and clinical reports. Currently, there are two methods of temporary clipping: 1) intermittent clipping, 2) continuous clipping. In many previous studies, the intermittent, repeated clipping technique was reported to reduce ischemic damage to the brain, but it is still debated. On the other hand, a comparison of the histological changes on the arterial wall between each clipping method has not been sufficiently reported yet. So the authors performed experimental temporary clipping on the common carotid and femoral arteries of about 25 rats using the Sugita temporary mini-clip. The specimens were divided into two major groups and seven subgroups: Group I (I-1, I-2, I-3, I-4, intermittent clippings for 5 minutes were done once, twice, three times, and few times), and Group C (C-10, C-15, C-20, continuous clippings for 10, 15, 20 minutes, respectively). The reperfusion time after the temporary clipping was the same as the clipping duration. Under light microscope, the histological findings by Hematoxylin-Eosin staining were examined in all specimens, which were obtained at each time interval after temporary clipping. Then the histological changes of the arterial walls by two different methods were compared with the normal specimen. The results suggest that intermittent temporary clipping is less damaging on the arterial wall than single continuous clipping.
