  • Distribution aspects and extinction threat evaluation of the endangered species, Rhynchocypris semotilus were investigated in Goseong-gun, Gangwon-do, Korea, June 2020. Among the 12 sampling sites investigated during the study period, samples of R. semotilus were collected 268 individuals at 6 sites. The streams inhabited of R. semotilus were Songhyeoncheon (3 stations), Gojindong (2 stations) and Osodong (1 station). The main habitats of R. semotilus were uppermost and upper stream (Aa type) with 3~15 m water flow width, 0.3~1.3 m depth and high ratio boulder and cobble bottoms. The estimated age of the R. semotilus (June) based on their total length distribution indicated that 0-, 1-, 2-, 3- and more than 4-year-old were 6~27 mm, 38~59 mm, 60~75 mm, 78~93 mm and 96~125 mm, respectively, and their has matured reproductive organs over two years old. R. semotilus investigation results of the threat of extinction showed no tendency to decrease in population size, but estimated to be less than 1,000 mature individuals, with a small range of extend of occurrence (39.668 km2), area of occupancy (16 km2), and number of disconnected locations (3 locations). Therefore, R. semotilus is now considered vulnerable (VU D2) based on the IUCN Red List categories and criteria.

  • The present study explored Korean parents' perceptions of and behavior toward game use among teenagers in Korea. A total of 600 Korean mothers of teenagers residing in Seoul and five other metropolitan areas participated in the survey. The survey was constructed based on five categories of variables, including the overall perception of games and game use, specific attitudes toward game use, cognitions about and attitudes toward game addiction, factors predicting parental monitoring of children's game use, and views and opinions about what needs to be done to promote healthy game cultures as well as to prevent problematic game use among teenagers in Korea. Results indicate that the respondents' overall perceptions of and attitudes toward games and game use are negative. In contrast, attitudes toward game use of the respondent's own child are contingent upon various comparison standards. Results also indicate that the respondents tend to overestimate the possibility that their own child is addicted to games, and their perceptions of game addiction are based on a narrow range of behavioral symptoms. Additional analyses indicate that parental monitoring of teenagers' game use can be predicted by the theoretical model driven from Ajzen(1991)'s theory of planned behavior. Finally, results also indicate that, in order to deal with the problems associated with teenagers' game use, proactive approaches to promote healthy game cultures as well as various initiatives to prevent problematic game use are necessary. Implications of the findings and future direction were discussed.

  • Burning mouth syndrome(BMS) is defined as chronic, painful burning sensation in the oral mucosa. Treatments for BMS include medication and psychiatric interventions. Capsaicin, alpha-lipoic acid, and topical and systemic clonazepam showed more effective in reducing the symptoms of BMS in the previous studies. The purpose of this study is to evaluate of the therapeutic efficacy of systemic clonazepam in BMS and to elucidate the relationships between such a efficacy and various clinical features, including age, pain intensity, pain duration, previous dental history and condition of oral mucosa. A retrospective clinical records audit was performed of patients diagnosed with BMS between January 2011 and August 2012. Patients were prescribed 0.5 mg clonazepam two times daily. Pain was assessed by patients on an 11-point numeric rating scale (NRS; 0 to 10) before and 1-2 weeks after systemic administration of clonazepam. The efficacy of clonazepam was evaluated in terms of patient's age, initial pain intensity, pain duration, presence or absence of precipitating event, condition of the tongue, presence or absence of denture. A total of 50 patients (46 women, 4 men) were included in this study. The patients were divided into two or three groups according to above clinical features. The amount of mean NRS reduction in patients with severe initial pain was $3.33{\pm}2.74$, whereas that in patients with mild initial pain was $1.64{\pm}1.54$. The amount of mean NRS reduction in oldest patients was $3.53{\pm}1.94$ (${\geq}$70yrs), and those in another younger patients were $2.88{\pm}1.80$(< 60yrs) and $1.54{\pm}2.86$(60yrs ${\leq}$ age < 70yrs), respectively. It was concluded that the older patients and the patients with higher intensity of initial pain tend to show better efficacy of clonazepam. However, There were no statistically significant differences according to pain duration, presence or absence of precipitating events, tongue fissuring, and wearing dentures.

  • This study aims at estimating the consumer's demand and willingness to pay(WTP) for horse meat in Korea. Three econometric models are employed to examine the multiple layers of the demand, including the current demand, the potential demand and latent demand. Findings indicate a substantial demand for horse meat. Dichotomous choice contingent valuation method is used to elicit the WTP. We assess the mean WTP for horse meat using a double-bounded logistic model. As a result, consumers are willing to pay at 67.8 percent of the beef prices of the third quality grade to purchase horse meat. And, for the factors that influence on WTP, only sex, age and recognition of horse meat are statistically significant.

  • This study analyzed the factors related to labor market transition of job injured workers. The Workers' Compensation Insurance Panel data ver.1, which that was surveyed by the Korean Workers' Compensation & Welfare Service in 2013, was used. Four key findings were made: first, the economically inactive populations are 7.2% and unemployed is 22.3% of occupational accident workers who finished the treatment period; second, 31.5% of laborers who returned to a new workplace went into another type of occupation; third, the results showed that socio-demographic factors, such as gender, age and education years, injury-related factors, such as the treatment period and work limitation, and workplace factors, such as company size and employment status, were associated with the return to work; and fourth, a relatively higher proportion of people who has received occupational training could not return to work and the disability grade was not associated with the return to work. These results suggest that policy makers need to understand the characteristics of labor market transition of job injured workers and develop efficient intervention programs based on the transitional labor market.

  • The purpose of this study was to analyze how much demographic and disability-related characteristics influence the quality of life that employed and unemployed disabled people, and determine difference in the influence of those factors between the two disabled groups. For this purpose, the study utilized 1st-year(2016) data from the 2nd wave of the Korean Panel Study on Employment for the Disabled. The findings of this study can be summarized as follows. First, employment is a critical factor that influences the disabled's quality of life. Besides, there are some financial, socio-relational and physical factors on which that quality is heavily dependent. Second, employed disabled people's quality of life is even more influenced by financial factors, socio-relational factors and health state than demographic factors. Third, unemployed disabled people's quality of life is significantly influenced by some demographic factors like gender and age and some physical factors like disability grade and disability period as well as by factors found influencing employed disabled people's quality of life. Thus, the two disabled groups are different from each other in which factors influence their quality of life. Based on these findings, this study made suggestions for the disabled's better quality of life.
