송인명 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.

송인명 한국보건정보통계학회 2022 보건정보통계학회지 Vol.47 No.4

Objectives: Loneliness poses a serious health risk. However, little is known about the state of loneliness in the Korean population. This study analyzes the prevalence of and risk factors for loneliness with a particular focus on marriage status in Korean adults using nationwide survey data. Methods: Using individual-level data from the 16th Korean Welfare Panel Study in 2021, this study analyzed 9,422 participants aged 30 years and older, who responded to a question, “how many days during the past week did you feel lonely as if you were alone in the world?”. Multiple logistic regression analy- sis was conducted to examine the likelihood of feeling lonely at least once a week according to marital status and other sociodemographic characteris- tics (gender, education level, household income status, employment status). Multivariate-adjusted odds ratio (OR) and 95% confidence intervals (CI) were calculated. Subgroup analysis was conducted by sex. Results: 20.2% of the study population were estimated to have felt lonely at least one day a week. 52.4% of widowed individuals and 47.6% of the divorced reported being lonely. Widowed and single people were more than two times as likely to feel lonely as the married (OR = 2.60 for the widowed; OR = 2.43 for the single; p < 0.001). Divorce and separation increased the odds of feeling lonely (OR = 4.02; 95% CI, 3.20-5.04; p < 0.001). ORs for loneliness for all non-married statuses (widowed, divorced/separated, single) were greater in men than in women. Conclusions: Loneliness is a highly prevalent public health problem in Korean adults. Marital status was strongly associated with increased risk for loneliness. Public health policies should consider targeting individuals who are more susceptible to the risk of loneliness.

Sputter 薄膜의 垂直磁氣異方性과 回轉履歷損失

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.

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.

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.
