Purpose: Many university students are under a lot of job-seeking stress because the employment rate is low. This study sought to determine the relationship between job-seeking stress, self esteem, self efficacy and appearance management behavior amongst university students focusing on nursing. Methods: This descriptive correlational study evaluated the relationships between job-seeking stress, self esteem, self efficacy and appearance management behavior of 340 university students was conducted between September 1 and October 5, 2015. Results: The correlational analysis between job-seeking stress, self esteem, self efficacy and appearance management behavior revealed a negative correlation between job-seeking stress, self esteem and self efficacy and a positive correlation between job-seeking stress and appearance management behavior. In addition, age also correlated with self esteem, self efficacy and appearance management behavior. Conclusion: Stress correlated with self esteem and self efficacy and appearance management behavior. Therefore job-seeking stress may be reduced through not only self esteem and self efficacy enhancement programs but also management according to age.

자동차의 air-bag 장치에 실용될 수 있는 압저항형 단결정 실리콘 가속도센서 칩을 개발하기 위하여 결정 실리콘 미세구조의 제조방법을 확립하고, 단위공정의 검증을 통하여 일괄공정에 의한 PROTO-TYPE 칩을 만드는 기술을 연구하였다. 단결정 실리콘 미세구조는 선택확산법을 이용하여 정확히 선택된 영역에만 air-gap을 형성하여 미세구조의 측면식각을 방지하는 선택확산법에 의한 실리콘 마이크로머시닝 기술로 제조하였다. 일괄공정을 위한 단위공정확립을 위하여 PROTY-TYPE 8빔 브릿지형 가속도 센서를 제조하였다. 제조된 칩의 가속도에 따른 출력전압은 선형성을 나타내고 있으며, 감도는 약 50 ㎶/V·g로 나타났다. 이 감도는 50G용 가속도센서의 사양을 만족하지 못했다. 이는 공정에 의한 문제라기 보다는 가속도센서의 시뮬레이션에 의해 설계한 구조가 이미 원하는 감도에 못 미친다는 것으로 생각된다. 따라서 2차 공정으로 제조될 가속도센서의 파라미터를 SuperSAP 유한요소 패키지를 이용하여 실리콘 미세구조부의 파라미터에 따른 특성을 시뮬레이션하였다. 설계된 50G용 가속도센서의 mass Pad의 반경 및 빔 길이, 빔 폭, 빔 두께, 그리고 mass의 각 파라미터 값은 700 ㎛, 120 ㎛, 5 ㎛, 1.0 ㎎ 이었다. 반도체 공정기술, 관성질량 제조법 및 선택확산을 이용한 마이크로머시닝을 사용하여 일괄공정으로 8빔 브린지형 가속도센서를 제조하였다. We researched the establishment of the silicon microstructure fabrication technique to develop a piezoresistive type silicon acceleration sensor chip and the technique to make a proto-type chip by the verification of the unit-process. Silicon microstructure is fabricated silicon micro-machining by selective diffusion method. This method prevent a side-etching of microstructure because selective diffused region is only formed an air-gap. We fabricated a proto-type 8-beam bridge-type acceleration sensor to establish the unit-process for the batch-process. The output voltage of the chip represented linearity with acceleration, and the sensitivity was about 50 ㎶/V·g. But this sensitivity dosen't satisfy the requirements of a practical acceleration sensor. The cause of this result is assumed not process problem, but the structure designed by simulation isn't suitable already. Threfore, the characteristics of parameters of the acceleration sensor that will be fabricated by 2nd-process is simulated by SuperSAP finite-element package. The determined parameter values of beam length, beam width, beam thickness, mass, and mass radius are 120 ㎛, 5 ㎛, 1.0 ㎎, and 700 ㎛, respectively. We fabricated 8-beam bridge-type acceleration sensor by batch-process using a semiconductor process technique, proof-mass fabrication method, and micromachinig using selective diffusion.

Hui Yu,Yu Liu,Ya Liu,Dongliang Wang,Yuling Xu,Binan Jiang,Weili Cheng,Lixin Huang,Weineng Tang,Wei Yu 대한금속·재료학회 2023 METALS AND MATERIALS International Vol.29 No.7

The microstructure and mechanical properties of micro-alloyed Mg-0.5 wt%Ce alloys are investigated systemically in this study. It shows that Mg-Ce binary system is very sensitive to extrusion temperature. On the one hand, the high tensile yield strength (TYS) of 343 MPa was obtained by extrusion at 250 °C mainly due to the combined effects of profuse nano-precipitation phase, grain refinement, texture strengthening and high-density dislocation; On the other hand, the excellent elongation of 30% was acquired by extrusion at 300 °C resulting from the elimination of dislocations as well as the modification of texture.

「おぼゆ」「思ほゆ」「思はる」の用法

유춘희(Yu, Chun Hui) 국제언어문학회 2016 國際言語文學 Vol.- No.35

A classical verb 「oboyu」in Japanese is a word from changing of「omohoy u」, which is a verb 「omou」connected with a auxiliary verb 「yu」, and a previous form of 「oboyu」.「omoharu」, which was formed from connecting with 「ru」that has the previous form of auxiliary verb 「yu」, has similarity with 「omohoyu」in the character and meaning. In other words,「oboyu」 「omohoyu」「omoharu」can be postulated as words used within the same boundary in their meaning and usage.「oboyu」「omohoyu」「omoharu」are intensively appeared in mainly 『genjimonogatari』among literary works during Heian period of Japan. By the way, the cases that spontaneity is translated as possibility or passivity are found in the process of interpreting scenes.It can be postulated that「omohoyu」「omoharu」have the same use of spontaneity, possibility, and passivity if「oboyu」has the use of spontaneity, possibility, and passivity. Based on these points, each usage of 「omohoyu」「omoharu」 「oboyu」was examined. The following result was found by comparing them. 「oboyu」and 「omohoyu」have little difference for the usage in 『genjimonogatri』but they are in confrontation with each other over spontaneity and passivity. That is, 「omoharu」is used as passivity that is influenced by the movement of characters while 「oboyu」is used as spontaneity that a certain situation or event is naturally realized for its characters. To sum up,「oboyu」 (「omohoyu」) and「omoharu」have a contrasting relation of spontaneity and passivity. 「omoharu」has only role of passivity. That is, it can be interpreted that 「oboyu」「omohoyu」「omoharu」have a complementary relationship and they share their roles.

Necroptosis is the major cause of death in alveolar epithelial cells (AECs) during acute lung injury (ALI). Here, we report a previously unrecognized mechanism for necroptosis. We found an accumulation of mitochondrial citrate (citratemt) in lipopolysaccharide (LPS)-treated AECs because of the downregulation of Idh3α and citrate carrier (CIC, also known as Slc25a1). shRNA- or inhibitor–mediated inhibition of Idh3α and Slc25a1 induced citratemt accumulation and necroptosis in vitro. Mice with AEC-specific Idh3α and Slc25a1 deficiency exhibited exacerbated lung injury and AEC necroptosis. Interestingly, the overexpression of Idh3α and Slc25a1 decreased citratemt levels and rescued AECs from necroptosis. Mechanistically, citratemt accumulation induced mitochondrial fission and excessive mitophagy in AECs. Furthermore, citratemt directly interacted with FUN14 domain-containing protein 1 (FUNDC1) and promoted the interaction of FUNDC1 with dynamin-related protein 1 (DRP1), leading to excessive mitophagy-mediated necroptosis and thereby initiating and promoting ALI. Importantly, necroptosis induced by citratemt accumulation was inhibited in FUNDC1-knockout AECs. We show that citratemt accumulation is a novel target for protection against ALI involving necroptosis.

Renewable Low-viscosity Dielectrics Based on Vegetable Oil Methyl Esters

Hui Yu,Ping Yu,Yunbai Luo 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.2

Vegetable oil dielectrics have been used in transformers as green alternatives to mineral insulating oils for about twenty years, because of their advantages of non-toxic, biodegradability, and renewability. However, the viscosity of vegetable oils is more than 3 times of mineral oils, which means a poor heat dissipation capacity. To get low-viscosity dielectrics, transesterification and purification were performed to prepare vegetable oil methyl esters in this study. Electrical and physical properties were determined to investigate their potential as dielectrics. The results showed that the methyl ester products had good dielectric strengths, high water saturation and enough fire resistance. The viscosities (at 40℃) were 0.2 times less than FR3 fluid, and 0.7 times less than mineral oil, which indicated superior cooling capacity as we expected. With the assistance of 0.5 wt% pour point depressants, canola oil methyl ester exhibited the lowest pour point (-26℃) among the products which was lower than FR3 fluid (-21℃) and 25# mineral oil (-23℃). Thus, canola oil methyl ester was the best candidate as a low-viscosity vegetable oil–based dielectric. The low-viscosity fluid could extend the service life of transformers by its better cooling capacity compared with nature ester dielectrics.

Thematic Poster : TP-12 ; Experience of Pulmonary Rehabilitation in Patients with COPD in Regional Pulmonary Center

( Yu Hui Won ),( Jin Young Chun ),( Sung Hee Park ),( Jeong Hwan Seo ),( Myoung Hwan Ko ),( Yong Chul Lee ) 대한결핵 및 호흡기학회 2014 대한결핵 및 호흡기학회 추계학술대회 초록집 Vol.118 No.-

Background: Pulmonary rehabilitation (PR) has been demonstrated to reduce dyspnea, increase exercise capacity, and improve quality of life in individuals with chronic obstructive pulmonary disease (COPD). We report our experiences to operate PR program of COPD in our PR clinic which belongs to Regional Pulmonary Center in Chon-Buk area. Methods: From March to June 2014, hospital records of patients in our PR clinic were reviewed retrospectively. For inpatients program, initial assessment were done by rehabilitation physician and individualized PR programs were prescribed considering patient’s exercise capacity. PR program included aerobic exercise for 30 minutes, resistance training using elastic bandage, breathing retraining (diaphragmatic and pursed lip breathing), device training for secretion management using acapella, flutter, PEP device, and VEST (high frequency chest wall oscillation), and respiratory muscle training. Outpatient’s PR program was conducted as hospital based PR or home based PR for 8 weeks. Results: In our PR clinic, among total 154 patients who were consulted for PR, 84 (54.5%) was COPD with acute exacerbation (AE) (Table 1). No serious complications were developed during PR program. Eighteen patients (11.7%) refused to practice PR due to personal reasons. For outpatient clinic, eighteen (56.3%) of 32 stable COPD patients were included (Table 1). Characteristics for COPD patients who received PR program were described in Table 2. Among these COPD patients, 34.3% performed hospital based PR, 34.3% home based PR, 20% home-based PR with weekly or every two weeks hospital visit, and 11.4% was missed follow up. Conclusions: For 4 months, patients who underwent PR were gradually increased. Since PR program has been accepted essential, non-medical treatment for COPD, PR should be included to COPD treatment. Also, korean researches about clinical benefits of COPD management would be necessary to settle down PR in Korea.
