Purpose:
For students who have already decided on their career path by entering the aviation departments, this study aims to analyze organizational commitment and teamwork relationships using the Myers-Briggs Type Indicator (MBTI) personality type as a tool.
Methods:
In order to investigate the career choices of aviation workers according to MBTI personality types, a survey was conducted targeting enrolled in and graduating from the aviation departments, and organizational commitment and teawork were analyzed using SPSS WIN 21.0.
Results:
Sening, Feeling, and Perceiving were mainly found in students who chose cabin crew as their career, whereas students in department of flight crew and aviation maintenance showed high level in Instuition, Thinkg, and Juding. As a result of the analysis, the MBTI type for each career path of aviation students was mainly ENTP for flight crew students, ESFP for cabin crew students, and INTP for aviation maintenance students.
Conclusion
Even if students make their choice based on advice, subjective and objective judgments in choosing a career path, there are cases in which the chosen job does not suit them. Therefore, it is hoped that various indicators such as the MBTI will be used to help studnes choose their career path.

BACKGROUND: It is well established that vascular contraction is caused by not only an increase in cytosolic Ca2+ level but also activations of Ca2+-sensitizing mechanisms including protein kinase C (PKC) and low molecular GTP binding protein. However, the roles of PKC and RhoA, a low molecular GTP-binding protein, on the receptor agonist-mediated contraction in swine pulmonary artery has not been clarified. In the present study, we examined the contribution of PKC isoform and RhoA to the arterial stimulants-induced contraction in swine pulmonary artery. METHOD: The large (> 5 mm), medium (1-3 mm) and small (< 1 mm in outer diameter) sized pulmonary arteries were excised and the contractions were recorded isometrically. The contents and subcellular distribution of PKC isoforms and RhoA were detected using immunoblotting. RESULTS: In medium pulmonary artery, norepinephrine (NE, 10 nM-30micrometer) led contraction in a dose-dependent manner. In large and small pulmonary arteries, however, NE failed to induce a contraction. Adding of 12-deoxyphorbol 13-isobutyrate (DPB, 1micrometer), a PKC activator, developed muscle force in 1 mM EGTA-contained Ca2+-free physiological salt solution. The expressions of PKC alpha, elsilon were significantly increased in medium pulmonary artery. NE (10micrometer) evoked the translocation of RhoA from cytosol to the membrane but not those of PKC isoforms. In Ca2+-free physiological salt solution, DPB (1micrometer) caused a translocation of PKC isoforms. CONCLUSIONS: These results support that NE induces contraction via RhoA pathway but not PKC pathway in swine pulmonary artery.

BACKGROUND: Little has been known about the incidence, the relationship with H. pylori infection and the prognosis of the multiple gastric polyposis. Recently, it was suggested that the eradication of H. pylori infection led the disappearance of the gastric polyps associated with H. pylori. We carried out a prospective study to determine the effect of H. pylori eradication on multiple gastric polyposis associated with H. pylori. METHODS: From July 1997 through August 2000, 13 patients who had multiple gastric polyposis on upper gastrointestinal endoscopy were recruited for this study. After eradication of H. pylori, we performed follow-up endoscopy at 2-3 months and 5-6 months later. RESULTS: The topographical distributions of gastric polyps were as following : antrum only in 7 cases, antrum and lower body in 4 cases, antrum and fundus area in 1 case, and entire stomach in 1 cases, respectively. The histopathological findings were as following : 13 cases showed chronic active gastritis, 2 cases with hyperplastic polyps, and 1 case with adenomatous polyps. After eradication of H. pylori infection, regression of multiple gastric polyps occurred in 7 cases (53.8%). In 7 cases with regression, regression was observed in 5 cases with chronic active gastritis alone, 1 case with hyperplastic polyps, and 1 case with adenomatous polyps. The re-biopsy specimens in 7 cases with regression revealed that the grade of inflammation decreased from 2.2 to 1.5 by the histological index of the updated Sydney system. CONCLUSION: With these results, we may conclude that the development of multiple gastric polyposis might be closely related with chronic H. pylori infection, and the eradication of H. pylori could lead to the regression of polyposis.
