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.

Purpose: This study was conducted to examine the degree of career plateau in general hospital nurses, to examine the affects of career plateau on nurses' job satisfaction and nursing competency. Methods: The sample consisted of 234 general hospital nurses. Data were analyzed using t-test, ANOVA, Pearson's Correlation and Hierarchical Multiple Regression. Results: Nurses' career plateau was associated with their job satisfaction, nursing competency. A statistically significant difference in job satisfaction was career plateau, charge nurse or higher in position and resilience predicted 41% of variance in job satisfaction of general hospital nurses. A statistically significant difference in nursing competency was total clinical experience, career plateau, preceptorship experience, charge nurse or higher in position and resilience predicted 43% of variance in nursing competency of general hospital nurses. Conclusion: These results of this study as presented above show that general hospital nurses' career plateau is associated with their job satisfaction and nursing competency. Career plateau is the most important variable in nursing competency. Based on the findings, general hospital nurses' career plateau management is empirically verified as a useful and effective method to increase their job satisfaction and nursing competency.

Objective: The intestinal microbiota enhances nutrient absorption in the host and thus promotes heath. Qinghai semi-fine wool sheep is an important livestock raised in the Qinghai-Tibetan Plateau; however, little is known about the bacterial microbiota of its intestinal tract. The aim of this study was to detect the microbial characterization in the intestinal tract of the Qinghai semi-fine wool sheep. Methods: The bacterial profiles of the six different intestinal segments (duodenum, jejunum, ileum, cecum, colon and rectum) of Qinghai semi-fine wool sheep were studied using 16S rRNA V3-V4 hypervariable amplicon sequencing. Results: A total of 2,623,323 effective sequences were obtained, and 441 OTUs shared all six intestinal segments. The bacterial diversity was significantly different among the different intestinal segments, and the large intestine exhibited higher bacterial diversity than the small intestine. Firmicutes, Bacteroidetes, and Patescibacteria were the dominant phyla in these bacterial communities. Additionally, at the genus level, Prevotella_1, Candidatus_Saccharimonas, and Ruminococcaceae_UCG-005 were the most predominant genus in duodenal segment, jejunal and ileal segments, and cecal, colonic, and rectal segments, respectively. We predicted that the microbial functions and the relative abundance of the genes involved in carbohydrate metabolism were overrepresented in the intestinal segments of Qinghai semi-fine wool sheep. Conclusion: The bacterial communities and functions differed among different intestinal segments. Our study is the first to provide insights into the composition and biological functions of the intestinal microbiota of Qinghai semi-fine wool sheep. Our results also provide useful information for the nutritional regulation and production development in Qinghai semi-fine wool sheep.

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.

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.

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.

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.

The current study confirmed the existence of an ip prosodic level in French intonation structure, as previously proposed by Sun-Ah Jun & $C\acute{e}cile$cile Fougeron (2000). However, in contrast to the previous suggestion of the plateau realized in an ip in several syntactic structures, the current study supposed that the plateau doesn't come from the different type of syntactic structures but arise from the unspecified syllables without any PA in an ip. Because if we limited ip phrasal tone to the syntactic structure, it would be difficult to find the more general reasons of ip level. Besides /Hi/ and /$H^*$/ we also used /$Hi^*$/ for the focused syllable in the current study. In emphasized sentences, in general, /$Hi^*$/ appeared in the first or second syllable of a leftward AP in an ip and /$H^*$/ in the final syllable of a rightmost AP of an ip, In contrast to these PAs, /$Hi^*$/ might appear in any syllable in an ip, but not to far from /$H^*$/ because the duration time and length t of plateau realized between /$Hi^*$/ and /$H^*$/ or /Hi/ and /$H^*$/ would make an essential harmonious rhythmic unit, Therefore, the current study determined the duration time and the number of syllables realized in each plateau in an ip level composed of more than one AP. As a phrase constituent structure, there is a practical need for intermediate prosodic units to allow for generalization over the many possible combinations of prosodic patterns that can occur. Further evidence is still needed to analyze and relate the different pitch ranges of the plateau of an ip according to the syntactic structure, to identify the considerable character in the French prosodic hierarchy.

The changes of plastic plateau in the stress-strain curves of annealed polypropylene (PP) films during stretching under room temperature were followed and the corresponding melting properties and microstructure were characterized by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). It was found that during stretching the plastic plateau disappeared progressively with the increase of drawing ratio. At the same time, the endotherm plateau in DSC curves also disappeared progressively. The presence of the plastic plateau was attributed to the stretching of unstable crystalline part which was formed by tie chains around initial row-nucleated lamellae structure during annealing. During stretching, the unstable part was stretched and converted to bridges connecting separated lamellae. There was direct relationship between the disappearance of plastic plateau and pore formation.
