최근의 4차 산업혁명은 디지털 전환에 따른 변화를 가속화하고 있다. 이러한 추세에 따라 기존의 창업 패러다임이 변화하고, 새로운 기술과 창조적인 아이디어에 의한 신규 비즈니스 모델이 등장하고 있다. 또한, 온라인 멘토링(e-mentoring), 역 멘토링(reverse mentoring), 그룹 멘토링, 다중 멘토링(Multiple mentoring) 등 멘토링 관계 및 환경의 다양성도 증가하고 있다. 하지만, 창업 현장에서 주로 활동하고 있는 5060세대 대부분의 멘토는 그동안 자기 경험과 전문성에 기반하여, 멘티에게 많은 도움을 줄 수 있었지만, 새로운 기술과 환경에 대한 이해도 및 경험 부족으로, 변화하는 환경에 대응하는 데 많은 어려움을 겪고 있다. 이러한 변화에 잘 대처하기 위해서는 새로운 기술과 환경에 대한 이해도를 높이기 위해 끊임없이 공부해야 하며, 최신 기술을 습득하고 적용해 나가야 한다. 또한 멘토링 관계와 환경의 다양성에 대한 이해와 존중을 갖추어야 하고, 이를 적극적으로 활용하여 멘토링의 효과를 극대화할 수 있어야 한다. 그리고 멘토는 멘티의 성장과 발전에 직접적으로 영향을 미치는 존재임을 인식하고, 끊임없이 새로운 지식과 기술을 습득하여 전문성을 유지하고 발전시켜야 하며, 자신의 지식과 경험을 잘 정리하여 멘티에게 적극적으로 전달해야 한다. 이에 본 연구에서는 멘토링이 멘토의 개인학습 및 자기효능감을 통해 멘토의 직무만족도에 미치는 영향 관계에 대해서 실증적으로 분석하고자 했다. 실증 분석 결과는 다음과 같다. 멘토링의 기능 중 경력 기능과 역할 모델링은 매개변수인 개인학습 및 자기효능감과 종속변수인 직무만족도에 대하여 모두 긍정적인 영향을 미치는 것으로 나타났다. 반면 심리·사회적 기능은 개인학습에 대해서는 긍정적인 영향을 미치지만, 자기효능감과 직무만족도에 대해서는 영향을 미치지 못하는 것으로 나타났다. 그리고 매개효과를 분석한 결과, 경력 기능에 대해서는 매개효과가 모두 확인되었으며 역할모델링에 대해서는 자기효능감의 매개효과만이 확인되었다. 본 연구를 통해 멘토링이 직무만족도, 개인학습 및 자기효능감을 촉진하는 중요한 요소이며, 멘토의 만족도를 높이는 요인으로 개인학습과 자기효능감을 확인하였다는 점과 멘토링에 관한 연구의 초점을 멘티에서 멘토로 옮겨 멘토링이 멘토에게 미치는 영향을 연구하였다는 점에서 학술적 및 실무적으로 의미 있는 연구라 할 수 있을 것이다.

The emergence and use of synthetic cannabinoids have greatly increased in recent years. These substances are easily dispensed over the internet and on the streets. Some synthetic cannabinoids were shown to have abuse liability and were subsequently regulated by authorities. However, there are compounds that are still not regulated probably due to the lack of abuse liability studies. In the present study, we assessed the abuse liability of three synthetic cannabinoids, namely JWH-030, JWH-175, and JWH-176. The abuse liability of these drugs was evaluated in two of the most widely used animal models for assessing the abuse potential of drugs, the conditioned place preference (CPP) and self-administration (SA) test. In addition, the open-field test was utilized to assess the effects of repeated (7 days) treatment and abrupt cessation of these drugs on the psychomotor activity of animals. Results showed that JWH-175 (0.5 mg/kg), but not JWH-030 or JWH-176 at any dose, significantly decreased the locomotor activity of mice. This alteration in locomotor activity was only evident during acute exposure to the drug and was not observed during repeated treatment and abstinence. Similarly, only JWH-175 (0.1 mg/kg) produced significant CPP in rats. On the other hand, none of the drugs tested was self-administered by rats. Taken together, the present results indicate that JWH-175, but not JWH-030 and JWH-176, may have abuse potential. More importantly, our findings indicate the complex psychopharmacological effects of synthetic cannabinoids and the need to closely monitor the production, dispensation, and use of these substances.

Objectives: The purpose of this study was to examine the perception of dental hospital accreditation and the awareness and practice of infection control in dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygienists working at dental hospitals in Gwangju Jeonnam and analyzed from October 24, 2016 to September 22, 2017. Data were analyzed with the independent t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis using the Statistical Package for the Social Sciences software, version 21.0. Results: Compared to non-accredited dental hospitals, all three variables were high for accredited dental hospitals. In accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness (r=0.407) and practice (r=0.533) of infection control, and awareness of infection control correlated to its practice (r=0.725). In non-accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness of infection control (r=0.239), and awareness of infection control correlated to its practice (r=0.481). Accredited dental hospitals showed healthcare accreditation expectancy effects (${\beta}=0.258$) and awareness of infection control (${\beta}=0.556$), and non-accredited dental hospitals were influenced by the number of employees (${\beta}=0.567$) and awareness of infection control (${\beta}=0.376$). Conclusions: It is necessary to develop efficient and systematic infection control programs to improve the awareness and practice of infection control in dental hygienists and patient's safety in the clinical field.

A two-layer quasi-geostrophic numerical model is used to investigate the temporal variability of the East Korea Warm Current (EKWC), especially the separation from the Korean coast and the generation of warm eddies. An attention is given on the active role of the nonlinear boundary layer process. For this, an idealized flat bottom model of the East Sea is forced with the annual mean wind curl and with the inflow-outflow specified at the Korea (Tsushima) and Tsugaru Straits. Two types of separation mechanisms are identified. The first one is influenced by the westward movement of the recirculating leg of the EKWC (externally driven separation),the second one is solely driven by the boundary layer dynamics (internally driven separation). However, these two processes are not independent, and usually coexist. It is hypothesized that 'internally driven separation' arises as the result of relative vorticity production at the wall, its subsequent advection via the EKWC, and its accumulation up to a critical level characterized by the separation of the boundary flow from the coast. It is found that the sharp southeastern corner of the Korean peninsula provides a favorable condition for the accumulation of relative vorticity. The separation of the EKWC usually accompanies the generation of a warm eddy with a diameter of about 120 km. The warm eddy has a typical layer-averaged velocity of 0.3 m/s and its lifespan is up to a year. In general, the characteristics of the simulated warm eddy are compatible with observations. A conclusion is therefore drawn that the variability of the EKWC is at least partially self-excited, not being influenced by any sources of perturbation in the forcing field, and that the likely source of the variability is the barotropic instability although the extent of contribution from the baroclinic instability remains unknown. The effects of the seasonal wind curl and inflow-outflow strength are also investigated.

InGaZnO (IGZO) thin-film transistors (TFTs) are very promising due to their potential use in high performance display backplane [1]. However, the stability of IGZO TFTs under the various stresses has been issued for the practical IGZO applications [2]. Up to now, many researchers have studied to understand the sub-gap density of states (DOS) as the root cause of instability [3]. Nomura et al. reported that these deep defects are located in the surface layer of the IGZO channel [4]. Also, Kim et al. reported that the interfacial traps can be affected by different RF-power during RF magnetron sputtering process [5]. It is well known that these trap states can influence on the performances and stabilities of IGZO TFTs. Nevertheless, it has not been reported how these defect states are created during conventional RF magnetron sputtering. In general, during conventional RF magnetron sputtering process, negative oxygen ions (NOI) can be generated by electron attachment in oxygen atom near target surface and accelerated up to few hundreds eV by self-bias of RF magnetron sputter; the high energy bombardment of NOIs generates bulk defects in oxide thin films [6-10] and can change the defect states of IGZO thin film. In this study, we have confirmed that the NOIs accelerated by the self-bias were one of the dominant causes of instability in IGZO TFTs when the channel layer was deposited by conventional RF magnetron sputtering system. Finally, we will introduce our novel technology named as Magnetic Field Shielded Sputtering (MFSS) process [9-10] to eliminate the NOI bombardment effects and present how much to be improved the instability of IGZO TFTs by this new deposition method.

In this paper, Capstone Design Education Program Learning Model was developed and recommended in order to foster convergent talents armed with practical competences and real cooperative capabilities. In this era of convergence and creativity, the fashion world needs human resources with cooperative skills and true professional abilities. A case analysis, an in-depth interview, and 1,2 test method were used for data acquisition and analysis. The summary of this study is described below. First, this program needs to complement the NCS fashion design learning module. Second, material changes to creativity and practical competencies - knowledge, skills, and attitudes - of the students are assessed after applying Capstone Design to the NCS fashion design learning model. Third, the process of converging fashion curriculum with IT and electronic technology, developing a fashion design learning program, and applying the Capstone Design was tested to prove the effectiveness of convergent fashion design education. Among the changes observed between the trial and control groups, it was confirmed that sub-factors of creative personality, i.e. self-assurance and openness, were increased along with knowledge, core competences including communication capability, and self-directed learning capability. The greatest improvement on the technological side was observed in IT literacy while ability to respond to changes was also increased. Besides, effects were demonstrated in behavioral factors such as initiative, spirit of challenge, experience, and openness. Lastly, the Capstone Design Education Program Learning Model was proposed in order to foster convergent talents in the fashion world.

Junior Ranger is a self-directed interpretation program for young visitors at national parks in the United States. The success of this program can be largely attributed to the role of an activity book which is given an applicant free of charge at a visitor center. This study aims to analyze the main characteristics of activity books for 14 national parks' Junior Ranger and to draw some implications for Korean geomorphological education. Although the activity books are varied in size, volume and printing, all of them offer diverse activities which are composed of different contents related to park resources in four fields and are performed in different ways such as Q&A, picture and word game, and creative activity. The time-consuming activities including attendance at a ranger-led program prevent the participant from making a superficial visit to be a junior ranger. The implications of the study are as follows: Firstly, the geomorphological education for children is needed to be strongly based on field experience learning and to be more carried out using a way of game rather than conventional Q&A, suggesting that it encourages students not to lose their interest for learning. Secondly, it is also necessary for the learning contents to be focused on various resources related to landform as well as landform itself. In addition, a creative activity such as writing verse or drawing feeling should be more applied to the geomorphological education in order to enhance their effects on affective domain beyond cognitive one. It is likely to be an alternative approach to understand landform by internalizing a sense of landform.
