  • In this study, the physicochemical and sensory characteristics of such as enzymatically treated and texture modified elderly foods made with beef, squid, eel, and mackerel were investigated. The enzymatically treated squid sample showed the proper texture hardness level corresponding to Universal Design Food (UDF) level 1 and all other elderly foods showed hardness consistent with UDF Level 2. The moisture contents were higher than 70% in the enzymatically treated boiled down squid and the two texture modified samples made with eel and mackerel, respectively. The enzymatically treated beef and squid samples contained 25.26 and 21.73% of crude protein, respectively. One serving portion of these enzymatically treated samples provided over 50% of daily needed protein intake of 65 years and older. According to the sensory evaluation of the samples, elderly recognized the differences between all enzyme treatment samples and controls in terms of hardness and chewiness, which are the main factors of the elderly food. In addition, the easier swallowness of texture modified foods were perceived. The positive assessment of elderly on the enzymatically treated samples using beef and squid were confirmed by preference tests.

  • This study was designed to investigate the role of weight control in the formation of underlying pathology in eating disorder or eating related problems. The subjects were 304 college athletes(Male : 187. Female: 121) and they were divided into two groups according to need for weight control(Weght control group: 110, Weght non control group: 194). The authors used self report questionnaire which was composed of epidemiologic data, food habit scale, eating attitude test, scale for locus of control for weight, scale for food preference and eating behavior. And we also used Eysenck Personality Questionnaire of Korean standardized edition for assessment of personality characteristics, Beck depression inventory, and the scale of hypochondriasis. The results were as follows: 1) Body mass index and the amount of cigarrette smoking and alcohol drinking showed significant differences by sex but not by need for weight control. 2) Eating habit of female athletes was the worst in all athletes. The score of eating attitude test of female athletes was higher than that of male athletes but there was no significant difference by need for weight control. Food preference and eating related behavior was also different by sex. 3) There were no significant differences in all subscales of Eysenck Personality Questionnaire, Beck depression inventory, and the scale of hypochondriasis between two groups which were divided by need for weight control. Neuroticism score was higher in female atheletes and psychoticism score was the highest in weight control male atheletes. 4) There was no significant difference in number of population with abnormal EAT score(to-tal score$\geq$26) between two groups which were divided by need for weight control. 5) The score of eating attitude test had positive correlation with the score of psychoticism and the tendency of depression in weight control male athletes but not in non-weight control male athletes. In non-weight control male athletes, the score of eating attitude test had positive correlation with the score of lie scale. so its correlation is different from those of weight control male athletes. But in female athletes, the score of eating attitude test had significant positive correlation with the score of psychoticism in both groups. In conclusion, these results suggest that the differences of eating traits in athletes are depend upon the sex difference, not upon the need for weight control. and that the role of weight control in eating disorder or abnormal eating attitude differs according to sex.

  • The emergence and use of synthetic cannabinoids have greatly increased in recent years. These substances are easily dispensed over the internet and on the streets. Some synthetic cannabinoids were shown to have abuse liability and were subsequently regulated by authorities. However, there are compounds that are still not regulated probably due to the lack of abuse liability studies. In the present study, we assessed the abuse liability of three synthetic cannabinoids, namely JWH-030, JWH-175, and JWH-176. The abuse liability of these drugs was evaluated in two of the most widely used animal models for assessing the abuse potential of drugs, the conditioned place preference (CPP) and self-administration (SA) test. In addition, the open-field test was utilized to assess the effects of repeated (7 days) treatment and abrupt cessation of these drugs on the psychomotor activity of animals. Results showed that JWH-175 (0.5 mg/kg), but not JWH-030 or JWH-176 at any dose, significantly decreased the locomotor activity of mice. This alteration in locomotor activity was only evident during acute exposure to the drug and was not observed during repeated treatment and abstinence. Similarly, only JWH-175 (0.1 mg/kg) produced significant CPP in rats. On the other hand, none of the drugs tested was self-administered by rats. Taken together, the present results indicate that JWH-175, but not JWH-030 and JWH-176, may have abuse potential. More importantly, our findings indicate the complex psychopharmacological effects of synthetic cannabinoids and the need to closely monitor the production, dispensation, and use of these substances.

  • Most investment evaluations and economic assessments of road transport proposals in Korea omit a valuation of the time spent in transit for loads of freight. These days there were few attempts to estimate value of freight travel-time savings in Korea, but most of them included rail or marine with statewide area so that couldn't obtain unique travel-time savings for road freight transport. This study applied revealed Preference method and associated binominal logit models to estimate the value of travel-time savings in transit from an statewide survey of road freight transport in 1997. Data sets were segmented according to transport areas and business types. The results of this study showed that the value of freight travel-time savings varied wide ranges from 53,449 won per hour in urban transport to 29,397 won per hour in regional transport, that the use of statewide value of freight travel-time savings can drives wrong results into economic assessment, and that the use of adequate value of freight travel-time savings according to assessment area is very important.

  • The objective of this study was to analyze characteristics of distribution of amphibian species and the affecting ecological factors. For the study, habitat environment factors were determined and applied to a habitat suitability model for the data collected from the Seom River in Hoengseong County and Wonju City, Gangwon Province, Korea between March 2013 to October 2013. The analyzed amphibian species were Rana nigromaculata, Hyla japonica, Rana dybowski, and Rana rugosa Temminck and Schlegel, and a logistic regression model was used with the pseudo-absence data. The result of the model analysis suggests that the major factors for Rana nigromaculata are distance to vegetation and rock and that for Hyla japonica is waterway. Rana dybowski and Rana rugosa Temminck and Schlegel have similar habitat characteristics, but the latter is shown to be dominant due to its wider habitat preference. According to the species richness model, the analyzed amphibian species are shown to have tendency to move between valleys or streams. This study quantitatively analyzed habitat environment characteristics using species distribution model, however, there is a limitation in terms of analysis on food factor and connectivity with other species. Combined with additional density or habitat analysis on birds or fish, this study can lead to more comprehensive analysis on biological environment factors.

  • The offshore wind farm is increasingly attractive as one of future energy sources all over the world. In addition, the capacity of an offshore wind turbine gets larger and its physical characteristics are big and heavy. In this regard, a special port is necessary to assemble, store, and transport the offshore wind systems, supporting to form the offshore wind farms. Thus, this study aims to provide a policy maker which evaluation factors can significantly affect to the optimal site selection of a offshore wind port. For this, Fuzzy-AHP method is applied to capture the relative weights. The results of this study can be summarized as follows. Five criteria in level I was defined such as the accumulation factor, the regional factor, the economic factor, the location factor, and the consortium factor. Of these, the accumulation factor(37.4%), the location factor(34.2%), and the economic factor( 24.5%) were analyzed by major factors. In level II, three assessment items of each factor were selected so that total fifteen items were formed. To sum up, the site selection of offshore wind port should consider the density of the wind industry, cargo volume of securing the economic operation of terminals, the development degree of offshore wind related industry, and the proximity to the offshore wind farms. In other words, the construction of offshore wind port should be paid attention to considering not only the proximity to offshore wind farms but also the preference of turbine manufacturing companies.
