The effect of carrier gases (He, $N_2$) on the properties of Ti coating layers were investigated to manufacture high-density Ti coating layers. Cold spray coating layers manufactured using He gas had denser and more homogenous structures than those using $N_2$ gas. The He gas coating layers showed porosity value of 0.02% and hardness value of Hv 229.1, indicating more excellent properties than the porosity and hardness of $N_2$ gas coating layers. Bond strengths were examined, and coating layers manufactured using He recorded a value of 74.3 MPa; those manufactured using $N_2$ gas had a value of 64.6 MPa. The aforementioned results were associated with the fact that, when coating layers were manufactured using He gas, the powder could be easily deposited because of its high particle impact velocity. When Ti coating layers were manufactured by the cold spray process, He carrier gas was more suitable than $N_2$ gas for manufacturing excellent coating layers.

최근 전체 노동 인구에서 비정규직 근로자가 차지하는 비중이 증가함에 따라 비정규직근로에 대한 학술적 연구도 증가하고 있는데, 많은 기존 연구들은 주로 거시적, 제도적 관점에서 현상을 설명하고 있다. 본 연구는 미시적 관점에서 비정규직 근로자 개인의 심리적 특성 및 행동을 살펴보고 있다. 사회정체성 이론에서는 낮은 지위의 집단에 소속되어 있는 개인은 부정적 사회정체성을 경험하는데, 이를 개선하기 위한 노력의 방향과 강도를 결정하는 요인으로 자신이 소속된 집단의 사회구조적 상황에 대한 인식이 중요함을 강조하고 있다. 사회구조적 상황에 대한 인식은 이동가능성, 지위 정당성, 그리고 지위고착성으로 설명된다. 비정규직 상황에서 이동가능성은 소속회사에서 정규직으로 전환가능성에 대한 지각, 지위 정당성은 조직 내에서 비정규직 지위 및 처우에 대한 정당성 지각, 그리고 지위 고착성은 비정규직 지위가 향후 사회적 및 경제적으로 개선될 수 있는지에 대한 지각을 말한다. 본 연구는 세 가지 사회구조적 특성이 직접적으로, 그리고 상호작용을 통해 비정규직 근로자의 조직몰입에 영향을 미칠 것이라는 가설을 설정하였다. 연구를 위해 2010년 한국 노동패널 제13차 데이터의 비정규직 근로자 323명의 응답을 분석하였다. 분석 결과 사회정체성 이론에서 제시하는 사회구조적 상황인 이동가능성, 지위 정당성, 그리고 지위 고착성이 비정규직 근로자의 조직몰입에 유의미한 영향을 미치는 것으로 나타났다. 구체적으로 현 조직에서 비정규직에서 정규직으로 이동가능성을 높게(β = .097, p < .10), 지위 정당성을 높게(β = .126, p <.05), 그리고 지위고착성을 낮게(β = -.195, p < .01) 지각하는 비정규직 근로자일수록 높은 조직몰입을 보였다. 가설과는 달리 이들 간의 상호작용 효과는 유의하지 않은 것으로 나타났다. 연구결과를 바탕으로 비정규직 근로자들의 조직몰입을 향상시킬 수 있는 실무적인 방안을 제시하고 연구의 한계점 및 추후 연구방향을 논의하였다. This study explores factors that may affect the organizational commitment of contingent workers, which previous studies have produced mixed findings. We argue that contingent workers' perception of social structural contexts can help explaining such inconsistency in research findings. Social identity theory (SIT) suggests that an individual's self-concept is shaped through his or her social identity. In association with our research problem, SIT provides the important prediction that the perceived social structural contexts of an organization's low-status members influence their attitudes and behaviors; individuals who belong to a low-status group will experience a negative social identity and will make efforts to improve their identities positively. The direction and intensity of such efforts are determined by perceived social structural contexts, status legitimacy, and status stability. Specifically, we hypothesized that contingent workers who perceive high on group permeability and status legitimacy, and low on status stability would show organizational commitment strongly. To test our research predictions, we used the 13th KLIPS (Korean Labor & Income Panel Study) data collected by the Korea Employment Information Survey (N = 323). The results of hierarchical regression analysis showed that group permeability, status legitimacy, and status stability were significant factors for determining organizational commitment. However, the interaction effects of the social structural contexts were not significant. This paper highlights the importance of social structural contexts to predict contingent workers' organizational commitment. We discuss the theoretical and practical implications of our study.

인사제도 실행의 일관성이 조직성과에 미치는 영향

이명주(Lee Myeong ju),이경환(Lee Gyeong hwan),조봉순(Cho Bong soon) 한국인적자원관리학회 2017 인적자원관리연구 Vol.24 No.1

본 연구는 기업에서 도입한 인사제도를 얼마나 일관성 있게 실행하는 지가 조직성과에 미치는 영향을 살펴보았다. 기존 연구들은 어떠한 인사제도가 또는 인사제도의 번들이 기업성과에 미치는지, 그리고 어떠한 과정을 거쳐 이러한 성과가 나타나는지를 주로 살펴보았다. 본 연구는 인사제도의 운영과정 상의 특징에 주목하여, 인사제도 실행이 지속적으로 이루어지는 것이 중요하다는 입장에서 인사제도의 비일관성이 높으면 기업성과에 부정적인 영향을 미치며, 이러한 효과는 종업원들의 회사에 대한 신뢰가 높은 경우 약화된다는 가설을 설정하였다. 한국직업능력개발원의 HCCP 데이터를 활용하여 이상의 가설을 검증하였는데 2009년(3차년도)부터 2013년(5차년도)년도의 제조업체를 대상으로 총 202개 기업, 연도-기업 관측치는 446개를 최종 분석에 포함되었다. 인사제도의 일관성은 2009, 2011, 2013년 3회의 조사기간에 걸쳐 실행된 인사제도 수의 변화와 도입 및 폐지된 인사제도의 수를 기준으로 측정하였다. 분석결과는 본 연구의 주요 가설을 지지하는 것으로 나타났다. The purpose of this paper is to examine the effects of the consistency of human resource (HR) practices on organizational performance. It also attempts to show the moderating effects of trust as it relates to HR practices and organizational performance. To test these effects, we used Human Capital Corporate Panel (HCCP) data collected through the Korea Research Institute for Vocational Education and Training. This study employed the third-wave data collection in 2009 through the fifth-wave data collected in 2013. We tested our model based on a sample of 202 companies (446 samples of year-company) in Korea. The results of the present study supported the hypothesized moderating effect of organizational trust in the consistency of HR practices–performance relationship. Specifically, the findings showed that inconsistency in HR practices negatively influences organizational performance. We also found supporting evidence for a moderating effect of organizational trust in consistency of HR practices on performance. However, when the employees level of trust level was high, the consistency of HR practices had a weak negative impact on corporate performance. This study advanced our understanding of the mechanisms linking HR practices to organizational performance by focusing on consistency in human resource management. Based on empirical evidence, we discussed the direction of suggestions and future research to clarify the significance of the study.

The present study attempts to investigate the knowledge, belief, attitude and behavior of healthcare major students and non-healthcare counterparts concerning their oral hygiene. The purpose is to provide basic data for positive oral health activities to the students with non-healthcare major, who tend to have insufficient information on oral hygiene. A survey was conducted to 400 students in K college in Incheon from May 1-30, 2003. A total of 384 surveys were analyzed using the SPSS program Version 10.0. The result is as follows: 1. There was a statistically significant difference in the knowledge on oral hygiene between the healthcare(M=3.08) and non-healthcare(M=2.78) students (pE0,05). 2. As for the beliefs and attitudes toward oral health behaviors, 56.9% of the healthcare students and 60.6% of non-healthcare counterparts responded moderate to the question asking if they liked tooth-brushing. The reason they liked tooth-brushing were cleanliness(60.3% of healthcare and 71.9% of non-healthcare students). They didn`t like brushing their teeth because they felt it was a nuisance(60.6% of healthcare and 54.5% of non-healthcare students). 90.6% of healthcare students and 90.1 % of their non-healthcare counterparts said they wanted to keep their oral health intact. Most of the subjects seemed to acquire information on oral hygiene through mass media (62.2% of health care and 55.3% of non-healthcare students). The persons who give them oral health information are their friends or neighbors(26.8% of healthcare and 22.8% of non-healthcare students), and dental hygienists were the last in the list of the sources of information (3.4% of healthcare and 2.5% of non-healthcare students). 3. Their oral health behaviors were also considered. 64.4% of the healthcare students and 53.7% of the non-healthcare counterparts brush their teeth once or twice a day. 51.4% of the former brush their teeth for 2 minutes and 44.8% of the latter for 3 minutes. Some of them use oral health measures other than tooth-brushing (13.3% of healthcare and 14.3% of non-healthcare students). Not many of them used oral health products(6.6% of healthcare and 5.9% of non-healthcare), and the difference was statistically significant(pE0.05). The largest number of healthcare students brush their teeth right before going to bed(29.9%), while their counterparts do it after breakfast(25.8%).

Objectives: The purpose of this study is to develop a coping plan for verbal abuse in dental hygienists, to improve work environment and performance ability and to offer basic data for reducing turnover rate through surveying verbal abuse degree that dental hygienists experience, and through grasping its effect on job stress, turnover intention and burnout. Methods: A questionnaire survey was conducted from November 18, 2019 to December 6, 2019 targeting 215 dental hygienists who are working at dental hospitals and clinics where are located in Gyeongnam and Busan Metropolitan City. The results are as follows. Results: The verbal abuse in dental hygienists was indicated to be in order of the verbal abuse from patients with 2.00±0.78, the verbal abuse from doctors with 1.91±0.78, and the verbal abuse from Yokefellow with 1.88±0.79. A type of verbal abuse was shown to be the largest in ‘I ve ever been spoken informally. As a result of having analyzed general characteristics, a dentist s verbal abuse was significant in workplace and turnover experience And the verbal abuse was significant in work placeas for turnover intention and in service career as for job stress and burnout. All in the verbal abuse from dentists, the verbal abuse from Yokefellow and the verbal abuse from patients showed statistically significant positive correlation with job stress, turnover intention and burnout. Accordingly, the dental hygienists appeared to have higher job stress, turnover intention and burnout in the more experiences of verbal abuse from patients. Conclusions: To help dental hygienists effectively cope with verbal violence, development of situational manuals and training of programs for prevention and arbitration of verbal violence is necessary.
