      • 現行 高等學校 物理 敎科書의 比較 分析 硏究

        宋寅命,李春雨,李聖瑞 공주대학교 사범대학 과학교육연구소 1982 과학교육연구 Vol.14 No.1

        An analysis on the main structure and contents of the current five physics text books of the high school was made from a statistical view point. Also some comparative characteristics of those five texts are checked and some ambiguities of physical representation are also pointed out. Finaly improvable suggestion for new curriculum of the high school physics are presented.

      • 國民學校 및 中學校의 科學科 敎育課程의 系列性에 關한 硏究(物理科學分野)

        宋寅命,禹榮均,金千中 공주대학교 사범대학 과학교육연구소 1976 과학교육연구 Vol.8 No.1

        The results of the examination for the new science curriculum shows that the selection and arrangement of the contents of the teaching subjects is reasonable, but that the contents is difficult and the quantity of the subjects is abandant in both side of teaching and learning is dominant opinion. The results of the sequence analysis of the teaching contents are as follows: (1) the selection of the fundamental concepts, the level of teaching in primary and junior high school, and the sequence of the contents are of no gross faults. (2) The sequence of the "Waves" included the properties of light is cut off, because they do not deal with the waves in the energy concept in junior high school. (3) The unit, "Magnetic Effect of a Current" is dealt with in interaction unit in primary school, and on the other hand it is dealt with in energy unit in junior high school. So, there is room for examination in magnetic effect of current from a viewpoint of the concept development and sequence maintenance. Next, we discussed the theoretical background for the formation of sequence and especially have set up the hierarchy of the inquiring process, in the viewpoint of organizing the contents and techniques dealt with in inquiring activities. And, on the basis of a survey of public opinion, analysis of sequences, and general theory of formation of sequence, we proposed the general rule for organizing the sequence of the concepts and the process-skills between the primary and the junior high school, and for organizing the sequence of the seience curriculum in itself. On the basis of these discussion, we have selected some unit and framed the teaching programme which will serve as a good reference to the practical teaching. We hope that a large number of teachers put the contents proposed in this paper and teaching programme organized process-skills into practical use, and they research and practice the various teaching techniques continuously in order to reach to educational purpose of the new science curriculum.

        Lifestyle changes and perceived restrictions in daily life during the COVID-19 pandemic: Analysis of the 2020 Community Health Survey data

        인명 대한산업경영학회 2022 산업융합연구 Vol.20 No.8

        This study aims to examine the extent of lifestyle behavior changes, perceived restrictions in daily life, and their relationship during the COVID-19 pandemic. Using the 2020 Community Health Survey data, this study calculated perceived restrictions in daily life among adults in Korea during the pandemic by sociodemographic characteristics and lifestyle behavior category (physical activity, sleeping duration, drinking, smoking, social contact, public transport use, food delivery, instant food consumption). The generalized linear model examined the relationship between behavior change and perceived restriction on daily life. A total of 227,808 respondents were analyzed. 56.70% of the population perceived their daily lives restricted by 50% and more during the pandemic. The majority of the population decreased physical activity, social contact, and public transport use (52.71%, 89.70%, and 63.74%, respectively). Individuals who decreased physical activity, sleep duration, and social contact frequency, and those who increased drinking frequency, food delivery, and instant food consumption perceived greater restrictions in daily life than those who did not change respective behaviors (p<0.001). In conclusion, decreases in social contact and physical activity and increases in use of food delivery and instant food consumption were associated with greater perceived restrictions of daily life during the pandemic. Efforts to alleviate the negative impact of the pandemic on psychological well-being may need to involve attempts to improve healthy life behaviors.

      • Sputter 薄膜의 垂直磁氣異方性과 回轉履歷損失

        宋寅命 공주대학교 사범대학 과학교육연구소 1984 과학교육연구 Vol.16 No.1

        Magnetization(Ms), magnetic perpendicular anisotropy constant(??), sin 2θ and sin 4θ component of Ku (??,??), rotational hysteresis loss(??) and rotational hysteresis loss integral(J) of sputtered ?? film and amorphous ?? film are obtained from measurement of the magnetic torque and M-M loop. The samples show suitable characteristics as a vertical magnetic recording media. Field dependence of ?? and ?? of the samples exhibits complex changes with increasing external field. After annealing, magnetization and perpendicular anisotrory constant of the films increased in CoCr but decreased in Gd Tb Fe, respectively, but distribution of ?? of the films does not implied transitional change of magnetization mode. It is presented a magnetization mode considered the Ganssian type random uniaxial anisotropy as well as ordinal uniaxial anisotropy. The mode utilized to analyse distribution of magnetic dispersion and rotational hysteresis loss in the films but the mode is not utilized to check the magnetization reversal mode. On the basis of calculated critical diameter of colmn(??), at which the magnetization reversal transition occurs from coherent rotation to curling, distribution of anisotropy, rotational hysteresis loss integral(J) and of observed columnar diameter of the films or magnetic bubble observations of other worker, proposed the magnetization reversal modes occurs in CoCr film and in GdTbFe film.

      • Prescribing patterns for attention deficit hyperactivity disorder medications among children and adolescents in Korea, 2007-2011

        인명,신주영 한국역학회 2016 Epidemiology and Health Vol.38 No.-

        OBJECTIVES: This study analyzed the prevalence of attention deficit hyperactivity disorder (ADHD) medication use among children and adolescents in Korea between January 1, 2007 and December 31, 2011. METHODS: Using the Korea National Health Insurance claims database, we identified patients between one and 17 years of age who had at least one medical claim for the diagnosis of ADHD (International Classification of Diseases, 10th revision: F90.0). The annual prevalence of ADHD diagnoses was calculated, using national census data from Statistics Korea on the population aged between one and 17 years as the denominator. The prevalence was age-standardized using the 2010 population as the standard population. The number of patients who were treated with methylphenidate and/or atomoxetine and the prevalence of total patients with ADHD that were treated with either drug were also calculated for each year. All analyses were stratified according to gender and age group (1-5 years, 6-12 years, and 13-17 years). RESULTS: The number of patients diagnosed with ADHD increased from 72,704 persons (0.71%) in 2007 to 85,468 persons (0.93%) in 2011. The annual age-standardized prevalence of ADHD diagnoses increased from 0.67% in 2007 to 0.94% in 2011. The prevalence of methylphenidate use among children and adolescents with ADHD decreased from 73.91% in 2007 to 70.33% in 2011, whereas that of atomoxetine use increased from 5.77% in 2009 to 13.09% in 2011. CONCLUSIONS: While methylphenidate remains the most commonly prescribed ADHD drug, the use of atomoxetine has increased.

      • 제조업체에서의 생산공정유형과 환경경영활동간 관계에 관한 연구

        인명,김지수,정은재 한국경영과학회 1998 한국경영과학회 학술대회논문집 Vol.- No.1

        Many studies expressed the necessity of dynamic environmental management strategy considering production ● product type, industry conditions, local situations. In this respect, some researches examined the integration between operations management(O.M.) strategy and environmental management (E.M.). With theoretical background of these researches, this study performed a case study on the relationship between production process and environmental management practices. As our cases, Korean 4 companies are chosen, which are largely grouped into project shop process type company(1 shipbuilding company, 1 heavy machinery company) and continuous process type company(2 petro-chemical plant companies). The following results are identified: 1) the present level of environmental management pactices of all 4 companies is a receptive stage which is either just out of end-of-pipe control stage(in project shop type 2 firms) or mainly production process control through process change(in continuous type 2 firms). 2) In terms of operations management strategy, there exist some difference between project shop and continuous production process in competitive dimensions: i.e., project shop companies like shipbuilding and heavy machinery seem to pursue design capacity, delivery speed while continuous process companies to pursue cost and quality as order winning factors. 3) We could also find the difference of environmental management practices between project shop and continuous production process. Project shop companies are trying to enhance environmental capability development and corporate image while continuous process companies to achieve waste minimization and restoring. 4) There is some inter-relationship between O.M. strategy competitive dimensions and E.M. practices. In other words, strong relationship between cost reduction and waste minimization exists at continuous process type companies like petro-chemical plant, but at project shop type companies there is weak connection between design capacity/delivery speed and environmental capability/corporate image.

        Loneliness as a Risk Factor for Suicidal Ideation and Depressive Mood Among Korean Adolescents in 2020–2021

        인명 대한산업경영학회 2023 산업융합연구 Vol.21 No.5

        Suicide is the leading cause of death among Korean adolescents. There is a growing interest in the role of loneliness as a risk factor for suicide ideation and depressive symptoms. However, little is known in the Korean context. This study analyzed a total of 109,796 respondents from the Korea Youth Health Behavior Survey in 2020 and 2021. Multiple logistic regression models were implemented to test the association between loneliness and either of suicidal ideation and depressive mood. Covariates included demographic characteristics, school enrolled, household income, living arrangement, self-rated health, and the number of times treated for violence. Adjusted odd ratio (OR) and 95% confidence intervals (CI) were computed. 12.0% of adolescents reported to have felt lonely frequently and 3.0% always. 11.8% and 26.0% had suicidal ideation and depressive mood, respectively. The prevalence of suicidal ideation was higher in the always-lonely adolescents (52.6%) than in the frequently-lonely adolescents (35.1%). The always-lonely adolescents were nearly 30 times more likely to have suicidal ideation (OR=30.7; 95% CI, 27.1 – 34.8) and to feel depressed (OR=32.5; 95% CI, 29.2 – 36.4) than adolescents who felt never lonely. In conclusion, Loneliness was a major risk factor for suicidal ideation and depressive mood among Korean adolescents. Monitoring and addressing the condition of loneliness may help reduce suicidal ideation and depressive mood.
