최근 한국 사회는 반려견을 키우는 인구가 빠르게 증가하고 있다. 한국 사회의 주거환경 특성상 소형 견종을 반려하는 가정이 많은데, 시츄, 말티즈, 푸들 등이 이에 해당한다. 이들 견종은 흐르는 눈물 과다로 인한 문제를 겪는 대표적인 견종이다. 이를 개선하기 위하여 현재 시중에는 이미 다양한 제품이 나와 있으나 그중 몇 가지 제품에서 타일로신이 발견되어 논란이 되었다. 타일로신은 설사 위장장애 등의 부작용을 야기하여 수의사의 처방이 필요한 항생제이다. 이 때문에 한약재(Compound A, Compound B)을 활용하여 부작용이 없는 안전한 보조제를 개발하고자 한다. 실험에 참여하는 반려견의 몸무게에 비례하여 2주간 보조제를 복용하고 눈물검사키트를 사용하여 전과 후를 비교하고 육안으로 확인되는 변화를 관찰한다. 실험 결과 전체적으로 흐르는 눈물의 양이 감소하였고, 부가적으로 발견한 효과로 눈물양이 부족하거나 과다한 반려견의 눈물양이 정상화된 것을 발견할 수 있었다.

환경에서 받는 스트레스는 질병의 원인이 되며 현대인의 주요 사망 원인이 되기도 한다. 그만큼 현대사회에서 받는 스트레스가 사람에게 큰 영향을 주는 만큼 스트레스를 해소하는 것이 중요한데 스트레스를 해소하는 여러 방법 중 하나로 치유곤충에 대해 조사해 보았다. 치유곤충은 소리치유, 관찰치유, 음식치유 3가지로 구성되어 있으며 소리치유는 쌍별 귀뚜라미나 방울벌레 등의 울음소리를 들을 수 있게 돼 정서적 안정감을 높일 수 있는 치유이며 관찰치유는 곤충을 키우면서 노인들의 우울증과 인지기능 개선을 통한 정서적 안정에 도움을 주고 음식치유는 식용곤충을 이용한 치유 방법으로 식용곤충은 영양 가가 좋고 현대인의 질병을 치유하는데 많은 도움을 준다고 한다. 또한 2017년 72억명 수준 세계인구가 2050년에는 90억명을 넘어설 전망이며, 지구촌 전체가 심각한 식량난에 시달릴 것으로 예상되며 국제연합식량농업기구(FAO) 전문가들은 식량난과 영양소 부족 문제를 동시에 해결할 미래 식량 자원으로 곤충에 주목하고 있다. 앞으로 점점 중요해질 곤충 산업에 대해 사람들의 생각을 알아볼 필요성을 느껴 식용곤충에 대한 연령별로 조사하여 300명을 설문하였다. 설문조사에서는 향후 식용곤충에 대해 부정적이 응답이 꽤 높았으나 곤충의 외형이 남아있지 않는 가공식품이 향후 식용곤충을 먹겠다는 응답자 들에게서 인기가 좋은 것으로 보아 가공된 식품으로 대중화 한다면 긍정적인 결과가 나올 것으로 판단한다.

In this article, we reviewed how the therapy animals for animal assisted intervention (AAI) could be treated ethically in the aspects of animal welfare. Our goal is to reexamine the animal-human partnership from the animal's viewpoint to see what the benefits might be for the animal, or to see if the raising, training, and deployment of assistance and therapy animals is causing significant degradation in animal welfare. Also, we want to make an impression for AAI therapists to examine their ethical responsibility for the welfare of their therapeutic assisting animals. Animal assisted psychotherapist must respect the integrity of the animals and recognize that their rights and safety are safeguarded. In this article, we intend to provide recent advanced knowledge on the animal welfare and ethical reference in the filed of animal-assisted intervention.

Digital games are conducted by the interaction between players and characters. Even if it’s same in the MOBA games, the characters in these games are not the ones which players can bring themselves in. But they do occur player’s semiotic process by controlling them. To prove this hypothesis, this study analyzes the correlation between MOBA game player and game character based on the player’s consumption behavior. The two MOBA games, League of Legends and Heroes of the Storm have been selected for the study, by the reason of semiotic difference between the characters. As focusing on the particular structures of MOBA games, this study can confirm the characteristic of this game genre.

Adolescence is the most important period of healthy development. The purpose of this study was to evaluate the food recognition, snack preference, and dietary behavior of 1st grade of middle and high school boys and girls. Subjects were 5,554 students from 16 schools with healthy tuck shop and 3,406 students from 9 schools without healthy tuck shop in Seoul, Korea. Students from schools with healthy tuck shop are significantly higher than control group for facility satisfaction and hygiene satisfaction (all p<0.05). For fruit, the preference (p<0.05) and recognition (attitude, p<0.001: intention, p<0.05: eating habit, p<0.001: social-environment, p<0.001: self-efficacy, p<0.001) of students in schools with healthy tuck shop are significantly higher than those in schools without healthy tuck shop. For the habit of checking the manufacturer, students in schools with healthy tuck shop were significantly higher than students in schools without healthy tuck shop (p<0.05). The result suggested that we have to create an environment in which fruits can be purchased easily at a tuck shop and to educate adolescents for the importance of healthy food purchasing behavior. In conclusion, healthy school tuck shop had a positive effect on accessibility to healthy food.

The purpose of this study was to compare the validity of obesity indices among the body mass index (BMI), waist circumference (WC), and body fat percentage (BF%), and to determine which is the most useful index to predict the risk of chronic diseases of elderly people. This study was conducted as a cross-sectional study at welfare centers in Seoul. The total number of subjects was 261 (68 men and 193 women) with age ≥60 years. The distribution of obesity using 3 obesity indices in the subjects with hypertension, diabetes, or arthritis was BF%>WC>BMI in elderly men and WC>BF%>BMI in elderly women. In elderly women, odds ratios (ORs) for hypertension in BMI and WC quartiles were significantly increased in quartile 2 and 3 (p<0.05). The ORs for hypertension, hyperlipidemia, and arthritis in BF% quartiles were significantly increased in quartile 3 and 4 (p<0.05). The BF% was sensitive obesity index for predicting the occurrence of chronic disease in men, and the WC was sensitive index in women. Our results suggested maintaining BMI less than 23.5 kg/m2, WC less than 82 cm, and BF less than 35% in order to prevent chronic diseases in elderly women.

Kim Jeong-yeon. 2012. Intimacy and Gender in Expressing Gratitude in L2. The Sociolinguistic Journal of Korea 20(2). pp. 115-147. This study examines how Korean learners of English perform the speech act of ‘gratitude’ according to the variables of intimacy and gender. In a contrastive analytic framework, their behaviors are cross-examined against Korean native and English native speakers in terms of their choice of strategies and uses of politeness markers. The data have been obtained from 43 Americans and 91 Koreans assigned to three groups: English native speakers, Korean learners of English, and Korean native speakers. A discourse completion test and a subsequent interview revealed Korean learners of English showed a similar pattern as Korean native speakers in the uses of politeness markers to emphasize their thanking by intimacy levels. However, the way in which they deal with gender in English was divergent not only from American but also from Korean. They depended on the strategy of compliment while performing the speech act of gratitude, and were inclined to use negative politeness strategies, similar to the Korean language group. Korean EFL textbooks and classrooms, therefore, need to include not only more diverse contexts in which ‘gratitude’ is necessary, but also the ways in which the English speech act is performed in a culturally appropriate manner.

Recently, one-dimensional semiconducting nanomaterials have attracted considerable interest for their potential as building blocks for fabricating various nanodevices. Among these semiconducting nanomaterials,, SnO2 nanostructures including nanowires, nanorods, nanobelts, and nanotubes were successfully synthesized and their electrochemical properties were evaluated. Although SnO2 nanowires and nanobelts exhibit fascinating gas sensing characteristics, there are still significant difficulties in using them for device applications. The crucial problem is the alignment of the nanowires. Each nanowire should be attached on each die using arduous e-beam or photolithography, which is quite an undesirable process in terms of mass production in the current semiconductor industry. In this study, a simple process for making sensitive SnO2 nanowire-based gas sensors by using a standard semiconducting fabrication process was studied. The nanowires were aligned in-situ during nanowire synthesis by thermal CVD process and a nanowire network structure between the electrodes was obtained. The SnO2 nanowire network was floated upon the Si substrate by separating an Au catalyst between the electrodes. As the electric current is transported along the networks of the nanowires, not along the surface layer on the substrate, the gas sensitivities could be maximized in this networked and floated structure. By varying the nanowire density and the distance between the electrodes, several types of nanowire network were fabricated. The NO2 gas sensitivity was 30~200 when the NO2 concentration was 5~20ppm. The response time was ca. 30~110 sec.

Transparent conducting oxide (TCO) films are widely used for optoelectronic applications. Among TCO materials,zinc oxide (ZnO) has been studied extensively for its high optical transmission and electrical conduction. In this study, the effectsof O2 plasma pretreatment on the properties of Ga-doped ZnO films (GZO) on polyethylene naphthalate (PEN) substrate werestudied. The O2 plasma pretreatment process was used instead of conventional oxide buffer layers. The O2 plasma treatmentprocess has several merits compared with the oxide buffer layer treatment, especially on a mass production scale. In this process,an additional sputtering system for oxide composition is not needed and the plasma treatment process is easily adopted as anin-line process. GZO films were fabricated by RF magnetron sputtering process. To improve surface energy and adhesionbetween the PEN substrate and the GZO film, the O2 plasma pre-treatment process was used prior to GZO sputtering. As theRF power and the treatment time increased, the contact angle decreased and the RMS surface roughness increased significantly.It is believed that the surface energy and adhesive force of the polymer surfaces increased with the O2 plasma treatment andthat the crystallinity and grain size of the GZO films increased. When the RF power was 100W and the treatment time was120 sec in the O2 plasma pretreatment process, the resistivity of the GZO films on the PEN substrate was 1.05×10-3Ω-cm,which is an appropriate range for most optoelectronic applications.

The purpose of this study was to investigate the value evaluation of foodstuff of 448 college students residing in the urban area. As a result of analyzing the value of each foodstuff, two to four factors were drawn from each foodstuff. The factors were classified into the social-conceptual factor, the preparatory factor, the quality factor, the economic factor, the subjective factor, and the complex factor. It was learned that the social-conceptual factor was dominant over the majority of college students in the evaluation of value of foodstuffs. There was a difference in the factor of the value evaluation for each foodstuff according to sex and the main growth region among the college students. A significant difference was found between the sexes regarding the preparatory factor and the economic factor. Also, in accordance with the main growth region, there was great difference in the social-conceptual factor(except for the Korean rice cake).

This study was conducted to investigate the efficacy of larval stages of three species, namely, Tenebrio molitor, Protaetia brevitarsis seulensis, and Ptecticus tenebrifer larvae, in degrading poultry manure, specially, broiler and duck manure. The survival rates of larvae were also noted. For the experiment, T. molitor (n=300), P. brevitarsis seulensis (n=60), and P. tenebrifer (n=300) hatched larvae were randomly divided into six groups with three replicates. The degaradation efficacy tests were then performed for 30 days in a laboratory. The test groups were as follows: T1, 110 g broiler manure + T. molitor larvae (n=50); T2, 110 g duck manure + T. molitor larvae (n=50); T3, 125 g broiler manure + P. brevitarsis seulensis larvae (n=10); T4, 125 g duck manure + P. brevitarsis seulensis larvae (n=10); T5, 105 g broiler manure + P. tenebrifer larvae (n=50); and T6, 105 g duck manure + P. tenebrifer larvae (n=50). The groups showed significant efficacy in degrading broiler and duck manure (p<0.05). The highest survival rates were recorded for T. molitor larvae in both manure types [T1 (92.67%) and T2 (50%)], followed by P. brevitarsis seulensis larvae (T4, 40%) and P. tenebrifer larvae (T6, 14.67%) in duck manure. Next, the survival rates of P. brevitarsis seulensis (T3) and Ptecticus tenebrifer larvae (T5) in broiler manure were 0%. In conclusion, these results point to the feasibility of using insect larvae to degrade broiler and duck manure.
