This study is to analyze and verify the effect of middle-aged and elderly adults’ life conditions on suicidal ideation through pessimism. As a research method, 542 people aged 50 or older were selected from the KGSS (2018) data and logistic regression analysis was performed with the SPSS 23 version program. As a result, among various life conditions, the economic dimension (homeownership) showed a negative effect on suicidal ideation and pessimism, while the family dimension (loss of spouse) showed a positive effect. The economic dimension showed a complete mediation effect, while the family dimension showed a partial mediation effect. Based on these research results, this study suggested the need for social response to the factors that reinforce the pessimism of the middle-aged and elderly and the policy practice plan for suicide prevention considering life conditions.

사서교사의 저작권 수업 방식이 고등학생의 저작권 지식과 태도에 미치는 영향 연구

오지민,김기영 한국정보관리학회 2018 정보관리학회지 Vol.35 No.4

This study aims to identify the effects of instruction methods on the students’ knowledge and attitudes to persue an effective instruction for information literacy. For this purpose, a copyright class as a quasi-experiment is provided to students in a high school in different ways including the teacher-centered lecture and the student-centered Jigsaw cooperative learning program. As a result, Group D (Jjgsaw method) showed the highest educational effectiveness among the four groups in terms of the knowledge of copyright. the group also showed higher instructional effectiveness compared to other groups in the practical attitude, which was one of the three types of attitude to copyright. 본 연구에서는 사서교사가 제공해야 할 정보활용교육의 일부로서 저작권 교육 관련 자료를 새로 개발하였다. 그리고 Jigsaw 협동학습법을 적용하는 집단과 강의식 교수법을 적용하는 집단, 아무런 수업을 하지 않는 집단으로 나누어 수업을 진행하였다. 수업이 끝나고 교수법이 고등학생들의 저작권 지식 및 저작권 태도에 미치는 효과를 분석함으로써 보다 더 효과적인 저작권 수업 방식을 모색하려 하였다. 실험 결과 저작권 지식 부분에서는 Jigsaw 협동학습법이 가장 높은 교육적 효과를 보였으며 저작권 태도 부분에서는 Jigsaw 협동학습법이 실천적 태도 부분에서 강의식 교수법보다 더 높은 교육적 효과를 나타내었다.

Fine Mapping of Grain Weight QTLs Using Near Isogenic Lines from a Cross between Oryza sativa and O. grandiglumis

오지민,안상낙,윤동범 한국작물학회 2010 Journal of crop science and biotechnology Vol.13 No.1

In a previous study, we reported the grain weight QTL, tgw2 in the 150 F2:3 lines derived from a cross between Oryza sativa subssp. Japonica cv. Hwaseongbyeo and HG101. This QTL was confirmed in F4 lines (CR1242) segregating for the target region. For fine mapping of tgw2, one F5 plant homozygous for the O. grandiglumis DNA in the target region was selected from CR1242 and crossed with Hwaseongbyeo to produce the F₂ and F₃ populations. QTL analysis using 490 F₂ plants confirmed the existence of tgw2 with an R² value of 28.0%. This QTL explained 61.3% of the phenotypic variance for 1,000-grain weight in 64 F₃ lines. Substitution mapping with 47 F₃ lines and 74 F₄ plants with informative recombination breakpoints in the target region was carried out to narrow down the position of the tgw2. The result indicated that tgw2 was located in the 384-kb interval between two SSR markers, RM12813 and RM12836. Annotation data of BACs in this 384-kb region revealed that forty-five putative genes exist in this interval including the GW2 gene responsible for grain weight and width. Considering the position of the QTL tgw2, it appears that tgw2 is functionally related to the gene GW2. However, the possibility that another unknown mechanism might be responsible for regulation of grain weight at tgw2 cannot be ruled out. Four QTLs for grain length, grain width, and grain thickness were also located in the same interval suggesting that a single gene is involved in controlling these four traits. Substitution mapping also indicated that two QTLs for grain weight and culm length, tgw2 and cl2, were tightly linked.

김천대학 대학생들의 모발관리 행태에 관한 연구

오지민 김천대학교 2000 김천대학교 논문집 Vol.21 No.-

This research was performed to investigate the behavioral differ-ences according to the age and regional group, gender in hair care types. The research is also focused to develop the educational pro-gram concerned with hair care, and maintain the basic statues for better health to the students. Futhermore, it could be possible to forecast the perspective way of Korean market in hair care fields. The result was not showed many difference in hair care state, but there was a significant difference in the hair care methods. The ratio 72.4% of freshmen replied that they shampoo everyday while only 41.9% of the sophomores wash their hair everyday. It shows that the sophomores realize the damage due to the over usage of shampoo. While 72.1% of the sophomores use shampoo and condi-tioner independently, 55.2% of the freshmen uses shampoo and con-ditioner at the same time. This tells us that shampoo and condition-er having the different functions are being used separately to well-educated students during the academic course. Also the sopho-mores showed a tendency to perm their hair much less frequently than freshmen. From these results, the freshmen classes is sup-posed to induce changes in hair care methods and perform the cor-rect hair care, and it is also considered that lots of professionals in hair care field are necessary to do teaching those students and hair care amateur.

A Case of Isoniazid Intoxication in a Dog

오지민,김홍석,Ji-Houn Kang,강병택,양만표,김학현 한국임상수의학회 2021 한국임상수의학회지 Vol.38 No.4

A seven-month-old castrated male Chihuahua weighing 1.6 kg presented with generalized tonic-clonic seizure following ingestion of isoniazid. Emergency treatment with three doses of diazepam (total 1.5 mg/kg, intravenous [IV]) and phenobarbital (15 mg/kg IV) was administered. The seizure stopped after administration of propofol (constant rate infusion [CRI]; 0.2 mg/kg/min). Blood analyses showed mildly increased serum blood glucose concentration, hyperkalemia, and hyperphosphatemia. On suspicion of isoniazid toxicity, activated charcoal (1 g/kg, orally), lipid emulsion (CRI; 9 mL/hr), and pyridoxine hydrochloride (70 mg/kg IV) were added to the treatment regimen. Twelve hours after presentation, the dog showed increased serum liver enzyme activities, serum blood urea nitrogen, and creatinine concentrations indicating hepatic and renal failure. Twenty-two hours after presentation, blood analysis still revealed increased liver enzyme activities, blood urea nitrogen, and creatinine concentrations with low blood glucose concentration. Twenty-six hours after presentation, the dog’s vital signs deteriorated and the owner elected for the dog to be euthanized. This is the first report of the clinical course of isoniazid toxicosis in a dog in South Korea. Furthermore, to our best knowledge, this is the first report where secondary multiple organ failure was observed due to isoniazid toxicosis. Clinicians should be aware of the possibility of isoniazid toxicosis in dogs. Rapid initiation of treatment after clinical recognition is warranted in such cases.

Sliding Mode Observer Driver IC Integrated Gate Driver for Sensorless Speed Control of Wide Power Range of PMSMs

오지민,김민기,석정희,양일석,허세완,박기태,김진성 한국전자통신연구원 2015 ETRI Journal Vol.37 No.6

This work proposes a highly efficient sensorless motor driver chip for various permanent-magnet synchronous motors (PMSMs) in a wide power range. The motor driver chip is composed of two important parts. The digital part is a sensorless controller consisting mainly of an angle estimation block and a speed control block. The analog part consists of a gate driver, which is able to sense the phase current of a motor. The sensorless algorithms adapted in this paper include a sliding mode observer (SMO) method that has high robust characteristics regarding parameter variations of PMSMs. Fabricated SMO chips detect back electromotive force signals. Furthermore, motor current–sensing blocks are included with a 10-bit successive approximation analog-to-digital converter and various gain current amplifiers for proper sensorless operations. Through a fabricated SMO chip, we were able to demonstrate rated powers of 32 W, 200 W, and 1,500 W.

미용사(메이크업) 과정평가형 국가기술자격의 대학 교육과정 운영 : 경북지역 G 전문대학을 중심으로

오지민,오지영 대한미용학회 2020 대한미용학회지 Vol.16 No.1

In 2015, course-based qualification (CBQ) was started to develop talents linked with industrial sites based on the national competency standards (NCS), which were set to build a competency-centric society. The CBQ for make-up artist was launched in 2018. The present study, through analysis of learners' awareness, achievement and satisfaction, attempted to provide basic data needed to operate curriculums linked with CBQ for make-up artists of cosmetologyrelated departments in different colleges. Results showed that those who completed CBQ, took the course to receive license to cultivate their practical skills. They also understood that the CBQ course is helpful to generate make-up artists. They were also aware of the strong connection of the curriculum with field jobs and the neccessity of the CBQ. They are highly satisfied with the curriculum. It becomes clear that there should be continued studies by academic major on the operation of the course-based curriculum because this can then help the college students obtain the national license after the completion of their course. For such license, the students need not to spend separate time or money. Such effectiveness of the course should develop confidence, and satisfaction in the students' mind.
