The Cheolwon-Pyeonggang Lava Plateau on the Chugaryeong tectonic valley is one of the most extensive volcanic areas in central Korea. However, formative age and process of the plateau still remains a controversial issue. This study presented OSL ages on the upper and lower sedimentary layers of basalt from four sites in the Cheolwon and Yeoncheon areas and estimated age and process of plateau formation based on sedimentary- and chrono-stratigraphy and topographic analysis. The results suggested that most of the initial topography of the plateau on the Cheolwon and Yeoncheon areas had been almost completed before approximately 90 ka. However, the last lava flow around Jangheung-ri, Cheolwon, seemed to occur until 20-30 ka and had led to complete the present plateau, while the last lava flow in the Jeongok area, Yeoncheon, was estimated to occur at approximately 40 ka.

Purpose - Korean women suffered from serious experience at unfair personnel practice in the work and coexistence between work and home affairs. The study examined woman workers' career plateau perception and success who worked for local public enterprises, that is to say, regional public corporation invested by local government, and investigated mediating effect of dual commitment as well as control effect of self-efficacy from point of view of various access to variables. Research design, data, and methodology - The study investigated women employees of regional public corporation by empirical analysis. The author collected 337 copies from 380 copies and made use of 325 copies after excluding copies with improper answer. SPSS 24.0 and AMOS 24.0 were used. Results - The study investigated effect of career plateau (structure and content) upon subjective career success (job satisfaction and career commitment) according to questionnaire material: First, not only structural plateau but also content career plateau had negative influence upon dual commitment (structure and career). Second, dual commitment had positive influence upon subjective career success from point of view of organizational commitment and career commitment. Third, structural career plateau had positive influence upon career success, and content career plateau had positive influence upon job satisfaction. Fourth, structural career plateau did not have significant influence upon job satisfaction, content career plateau and career satisfaction. Fifth, subordinate variables (organizational commitment and career commitment) had mediating influence upon career plateau cognition and subjective career success. Sixth, self efficacy did not control career plateau cognition and subjective career success. Conclusions - Women employee's career plateau cognition mediated dual commitment to have influence upon career success and to be likely to help career success theory study. Career plateau had negative influence upon dual commitment and career success of women workers. The study shall give base of counteraction from point of view of control and motivation of women workers thinking of career plateau.

This study tried to reveal incision rate and its change by formation of lava plateau in the Cheorwon-Jeongok area. Incision rates of 0.421 m/ka and 0.101 m/ka in the upper and lower reaches of Hantan-gang, respectively, were calculated from sites before formation of lava plateau. These incision rates indicate that the upper and lower reaches of Hantan-gang have much higher and slightly lower incision rates than streams with similar distances from the Taebaek Mountains. However, sites after formation of lava plateau mostly showed incision rates ranging from 0.5 m/ka to 0.9 m/ka. Streams flowed on the lava plateau revealed 2-3 times higher incision rates than unrelated-streams or paleo-streams to formation of lava plateau did. These results suggest that incision rate in the study area was greatly influenced by formation of lava plateau and resultant geomorphic avulsion with rearrangements of stream.

Purpose - The purpose of this study was to examine the relationship between organizational tenure, structural career plateau, and interpersonal deviant behavior for nurses. Moreover, this study also investigated moderating role of proactivity on the effect of organizational tenure on structural career plateau. Design/methodology/approach - This study utilized 448 nurses working at three different types of hospital. The Exploratory Factor Analysis (EFA) and the multiple regression analysis were conducted to verify the hypotheses. Findings - The results showed that organizational tenure is positively related to structural career plateau and structural career plateau is positively related to interpersonal deviant behavior. However, moderating effect of proactivity is not significant. Research implications or Originality - Nurses are critical to the competitiveness of hospital organizations considering the proportion of manpower and the role of nurses. One of the important factors that decrease the motivation of nurses is structural career plateau. This study analyzed the antecedent and consequence of structural career plateau. In addition, practical implications for resolving the problem of structural career plateau were provided.

본 연구는 R&D인력이 경험하는 경력정체를 구조적 정체와 직무내용 정체로 구분하여 조직몰입과 관계를 규명하면서, 추가적으로 개인의 연령 및 창의적 행동특성이 경력정체와 조직몰입의 관계에 미치는 조절효과를 분석하는데 초점을 두고 있다. 국내 정부출연 연구기관에 근무하는 418명의 R&D 인력을 대상으로 실증 분석한 결과, 첫째 구조적 정체와 조직몰입의 관계는 연령에 따라서 차이를 보인다. 즉, 주니어 R&D인력일수록 구조적 정체가 조직몰입을 감소시키는 효과가 강하게 나타났다. 둘째 직무내용 정체는 조직몰입에 부정적인 영향을 미치며 개인의 창의적 행동특성에 따라서 차이를 보인다. 즉, 창의적 행동특성이 강한 R&D인력의 경우에 직무내용 정체와 조직몰입의 부정적 관계가 더욱 강하게 나타났다. 이러한 분석결과를 바탕으로 R&D인력의 경력정체 이슈에 관한 이론적인 함의 및 실무적 시사점에 대해 논의하였으며, 끝으로 연구의 한계점 및 향후 연구방향을 제시하였다.

Objectives: This study analyzed the influence of the career plateau phenomenon and distributive justice among hospital nurses on their turnover intention and the moderating effect of proactivity on these correlations. Methods: Survey data from 459 out of 500 hospital nurses at 9 hospitals were collected and used for analysis. SPSS 24.0 was used for conducting regression, validity, and reliability analyses. Results: Career plateau was positively related to turnover intention, whereas distributive justice was negatively related to turnover intention. Proactivity strengthened the positive influence of career plateau on turnover intention. By contrast, proactivity alleviated the negative relation between distributive justice and turnover intention. Conclusions: This study empirically confirmed that career plateau and distributive justice are important antecedent factors of the turnover intention of hospital nurses. Proactivity played a key moderating role between these antecedent factors and turnover intention. Theoretical and practical implications of this study were also discussed.

Coenurosis is an important zoonotic helminthic disease caused by the larval stage of the tapeworm Taenia multiceps. This parasite typically infects the brain of the intermediate hosts, including sheep, goat, cattle and even humans. We report a case of T. multiceps infection in a yak confirmed by clinical symptoms, morphological characteristics, and molecular and phylogenetic analyses. The coenurus was thin-walled, whitish, and spherical in shape with a diameter of 10 cm. The parasite species was identified as T. multiceps by PCR amplification and sequencing of the 18S rRNA, cox1 and nad1 genes. Three gene sequences all showed high homology (all above 97%) with the reference sequences from different hosts. Moreover, phylogenetic reconstructions with the 3 published Taenia gene sequences confirmed that the Qinghai yak isolate was closely related to T. multiceps. Although there are advanced diagnosis and treatment methods for coenurosis, early infection is difficult to diagnose. Importantly, the findings of yak infection case should not be ignored due to its zoonotic potential.

This study was carried out to determine the pathogen-causing diarrhoea in sheep Ovis aries in the Qinghai Tibetan Plateau Area, China. A trophozoite was identified as species of ciliate alveolates infecting the sheep based on morphological characteristics examined by microscope. It was mostly spherical, colourless and transparent, with many vesicles. Macronucleus and contractile vacuoles could not be distinguished. Size of the trophozoite was $80-180{\times}70-150{\mu}m$ and its surface was covered with cilia. Molecular analysis based on sequences of 18S rRNA and ITS genes confirmed the ciliate species as Balantidium coli. According to the literature, there have been many epidemiological investigations of B. coli infection in pigs, monkeys and humans. To our knowledge, this was the first report of B. coli infections in sheep in the Qinghai Tibetan Plateau Area of China, or eleswhere around the world. Importantly, the sheep case was rare but raised our concern that B. coli may spread across species and expand its host range.
