  • In forest work, working conditions are very hard to improve. The proper distribution of work time and good posture is believed to bring about direct improvements such as accident prevention. On this, this study has analyzed forest workers' posture and their working hours in order to improve their working conditions in stone channel work. Authors has chosen several core elements of stone channel work to focus on, which include stone masonry, excavation of bed, moving stone, directing work, choosing stone, and breaking stone. The ratio of real working time over total working time was shown as 84.6%. As for the time ratio of each elemental work over the real working time, the stone masonry was 60.4%, the directing work was 15.1%, moving stone was 12.1%, choosing stone was 7.1%, breaking stone was 3.3%, and excavation of bed was 2.0%. According to the analytical results provided by OWAS, the ratio of category III (Work posture has a distinctly harmful effect on the musculoskeletal system) has shown that moving stone turned out 65.2%, choosing stone was 61.5%, stone masonry was 46.1%, breaking stone was 14.3%, excavation of bed was 12.5% and directing work was 6.8%. Furthermore, the ratio of category IV (Work posture with an extremely harmful effect on the musculoskeletal system) has shown that excavation of bed turned out 37.5%, breaking stone was 28.6%, stone masonry was 27.3%, choosing stone was 7.7%, moving stone was 6.1% and directing working was 4.5%. These results are expected to be utilized for the improvement with respect to both working methods in the stone channel work and the workers' working posture.

  • Purpose - The postponement strategy, which delays the form, place, and production of products as late as possible, has been widely considered as a competitive supply chain management scheme in an era of mass customization and modular manufacturing. An interesting business phenomenon is that not all manufacturing/logistics firms choose the postponement strategy. Given that postponement is a counter-measure to speculation, which has some advantages under certain environments, the current imprudent inclination toward the postponement strategy may cause firms to lose the potential of the speculation strategy, an alternative strategy in supply chain management. Building on the logistics and manufacturing literature, this study examines characteristics of two contrasting strategies, postponement and speculation, and major factors favoring each strategy. Research design, data, and methodology - We apply the profiling approach to two business cases, HP printer and LG mobile phone. The profiling approach is a method of choosing a particular strategy aligned with environmental factors. While various approaches have been used to check the fit between a business strategy and environmental factors, the literature on manufacturing strategy and logistics has commonly adopted the profiling approach. Major factors used in profiling variables are derived from the literature. Two samples, HP printer and LG mobile phone, are selected, because they represent major characteristics appropriate for each strategy. The profiling is based on data from semi-organized interviews with managers. Results - The profiling approach shows that the postponement strategy is a suitable one for HP printers. Most factors, such as product life cycle, large production volume, low-price, product value, and monetary density, support delaying end products until as late as possible. Despite some exceptions, such as delivery time and economy of scale, our analysis states that the overall profile of HP printer is favorable for the postponement strategy. On the other hand, LG mobile phone may adapt the speculation strategy. Although it has large production volume and low delivery frequency, most characteristics support the speculation strategy for this product. An interesting finding is that, despite common perception that advanced technology products such as mobile telephones favor the postponement strategy, profiling proposes the speculation strategy for this product. Conclusions - Our analysis shows that speculation is not the universal option for supply chain management, and that, when choosing a specific strategy, one should consider many factors simultaneously. A major implication of our work is to emphasize the role of environmental factors such as supply chain variables in choosing an inventory strategy, and the importance of fit rather than solely strategic orientation. A theoretical contribution is to demonstrate the benefit of the simultaneous consideration of business variables in choosing specific strategies. For practitioners, our work leads us to consider the existence and the potential of speculation as a counter-measure to postponement. In addition, the comprehensive framework in this research may be instantly used in examining a practical strategy.

  • 본 연구의 목적은 우리나라 예비 과학 교사들의 교직 선택 동기요인과 만족도를 조사하는 것이다. 이를 위해 우리나라 11개 대학의 예비과학교사 815명을 대상으로 설문을 수행하였다. 본 연구에 사용된 교직 선택 동기 설문지는 Richardson과 Watt(2006)의 연구에서 개발된 FIT(Factors Influencing Teaching Choice)를 사용하였다. 분석 결과, 우리나라 예비 과학 교사들의 교직 선택에 가장 크게 영향을 미친 것은 내재적 직업 가치였으며, 그 다음은 과거의 교수학습 경험과 사회적 기여에 대한 동기에 대한 응답 비율이 높아 외재적 가치보다는 내재적 동기와 이타적 동기가 높은 것으로 나타났으나 기존 연구결과에서 나타난 다른 나라들의 평균보다 낮았다. 한편, 자신이 교직에 적합한 능력을 갖고 있다는 응답 비율이 낮거나, 교직은 전문성이 요구되며 어려움이 요구된다는 응답비율이 높아 교직에 대한 자신감은 낮은 것으로 분석되었다. 교직선택에 대한 만족도를 살펴보면, 평균 5.36으로 대체적으로 만족하는 것으로 보이나, 호주, 미국 등의 응답 평균에 비해서는 낮은 것으로 나타났다. 성에 따른 차이로는 교직 선택에 대해 남자 예비 교사들은 자신이 교직에 적합한 능력을 갖고 있기 때문에 택하였다고 응답한 비율이 높은 반면 여자 예비 교사들은 타인의 영향이 더 컸다고 인식하고 있었다. 또한, 여자 예비 교사들은 남자들보다 교사직무의 행정적, 감정적 어려움 등의 직무부담을 크게 느끼고 있었다. 마지막으로 교직 선택에 대한 만족도와 가장 높은 상관관계를 보인 동기는 내재적 직업 가치였다. 따라서 예비교사들의 내재적/이타적 동기를 높일 수 있는 방안이 필요하며 성별 차이에 따른 차별화된 접근이 요청된다.

  • Purpose - Past research has not given much attention to the roles of consumers' social relationship type in the effects of justice type of service failure recovery alternatives on their satisfaction to the alternative exposed to them. Current research aimed at exploring the moderation role of consumers' social relationship central versus peripheral in the effects of justice types of service failure recovery alternatives on the recovery satisfaction, and this research also explored whether the level of satisfaction to interaction justice-focused alternative are significantly different between the two, their social relationship central and peripheral relationship. Research design, data, and methodology - 2(social relationship central versus peripheral) between-subjects design was employed. 50 participants for each experimental group there were. Participants of each group took forceful steps in choosing one between the procedural justice-focused alternative and the distribution justice-focused alternative. χ2-analysis was used to verify that the number of choosing each alternative becomes different between the two experimental groups, and a one way ANOVA was used to verify that the extent to which participants are satisfied to the alternative chosen by them becomes different between the two groups. Results - The number of participants choosing procedural justice-focused alternative at the group of social relationship central was larger than that at the group of social relationship peripheral, whereas the number of participants choosing distribution justice-focused alternative at the group of social relationship peripheral was larger than that at the group of social relationship central. And the level of satisfaction to procedural justice-focused alternative at the group of social relationship central was higher than that at the group of social relationship peripheral, whereas the level of satisfaction to distribution justice-focused alternative at the group of social relationship peripheral was higher than that at the group of social relationship central. In addition, the level of satisfaction to interaction justice-focused alternative was not significantly different between the two groups. Conclusions - Marketers should give attention to the type of justice when developing alternatives by which consumers' service failure can be recovered. They should suggest procedural justice-focused alternative to consumers under social relationship central, whereas they should develop distribution justice-focused alternative for consumers under social relationship peripheral. And in the process of recovering service failure they also should focus on interaction justice.

  • 우리나라 연평균 근로시간은 OECD 최상위 수준이다. 장시간 근로는 근로자의 생산성을 저해하고 일과 가정의 양립을 방해하는 등 삶의 질을 하락시키는 요인이 된다. 최근 정부는 시간제 일자리를 증가하는 등 유연근로제를 장려하고 있지만, 양질의 시간제 일자리가 부족한 현실이다. 시간제 근로는 일과 개인의 삶을 병행할 수 있게 하지만, 동시에 열악한 근로환경과 부정적인 사회적 시선을 보유하여 개인의 삶의 만족도에 미치는 영향이 전일제 근로와는 다를 것으로 예상된다. 특히 여성의 경우 노동시장에서 성별 격차를 경험하고 있으며, 일과 가정의 병행이라는 측면에서 시간제 근로가 삶의 만족도에 미치는 영향이 남성과 다르게 나타날 수 있다. 본 연구는 2017년도 "서울서베이 도시정책지표조사" 자료를 활용하여 근무유형-성별의 교차효과가 개인의 삶의 만족도에 미치는 영향을 순서형 로지스틱 회귀모형을 통해 실증적으로 분석하였다. 분석결과에 따르면, 삶의 만족도는 전일제 여성, 전일제 남성, 시간제 여성, 시간제 남성 순으로 높은 것으로 나타났다. 또한 시간제 여성 근로자가 낮은 삶의 만족도를 가질 확률이 가장 높은 반면, 높은 삶의 만족도를 가질 확률은 가장 낮게 나타났다. 대조적으로 전일제 남성 근로자는 낮은 삶의 만족도를 가질 확률이 가장 낮은 반면, 높은 삶의 만족도를 가질 확률은 가장 높은 것으로 나타났다.

  • Several kinds of analytic methods for genetic polymorphism in cattle, including bovine blood typing, PCR-RFLP, BoLA and microsatellite typing were described. A few respect to consider for choosing method for actual application of genetic polymorphism were emphasized. The probability of relationship between characteristics and gene concerned, repetibility and easiness of methods applied and the possibility of clarification for segregation pattern should be deliberated.
