본 연구는 USCG phase-II의 형식승인 기준인 자연상태 생물군집의 75 % 이상 유지하여야 하는 평가체계에 대비하여 자연생물군집 농축 및 선박평형수관리시스템(Ballast Water Management System, BWMS) 처리 전 후 생물사멸시험을 실시하였다. 자연 식물플랑크톤군집의 농축 조사는 중영양수계인 장목만과 부영양화수계의 마산만에서 동계에 수행하였다. 장목만과 마산만에서 1톤 기준으로 생물을 농축하였을 경우, 10-50 μm 크기 생물 현존량은 4.7 × 10⁴ cells mL-1과 0.8 × 10⁴ cells mL-1 이었고, 농축생물의 생존율은 90.4 %와 88.0 %로 각각 나타났다. 특히 장목만에서는 Skeletonema costatum-like species 같은 체인을 형성하는 소형 규조류가 극우점한 반면, 마산만에서는 <10 μm보다 작은 편모조류 및 체인을 형성하지 않는 대형 와편모조류(Akashiwo sanguinea, Heterocapsa triquetra)가 우점하였다. 이와 같은 우점종 세포크기의 차이로 장목만 농축효율이 마산만보다 높게 나타났다. BWMS 장비를 통과한 처리 당일 생물 사멸률은 장목만이 90.4 %로, 마산만의 93 %보다 약간 낮았고, 장목만에서 BWMS 처리 5일 경과 후, 대조군의 대상생물의 사멸률은 6.7 %로 나타났다. 처리군에서는 >99 %로 대부분 사멸되어, 시험생물로서의 적용 가능성을 확인할 수 있었다. 결과적으로 동계와 같이 해역내 생물량이 낮을 경우, 주간 8시간 수행한 네트의 생물농축만으로는 USCG Phase II의 형식승인 기준인 500톤 탱크에 1.0 × 10³ cells mL-1 이상으로 자연생물 개체수 밀도를 충족하기는 쉽지 않다는 것을 파악하였고, 이를 보완하기 위해서는 일정기간 자연생물을 대량 배양 및 채집할 수 있는 시스템 도입이 필요할 것으로 판단된다.

본 연구는 S. Typhimurium을 대상으로 paraformaldehyde 35%를 함유한 훈증소독제의 살균효과를 평가하기 위해 수행되었다. 예비 시험에서, S. Typhimurium의 현탁액 균수는 모두 3.9 × 108CFU/mL이었으며, 훈증소독제에 노출시킨 모든 담체의 균수는 평판배지법과 여과법으로 배양한 시험균주 현탁액의 균수의 50%보다 많았다. 또한, 대조담체로부터 회복된 S. Typhimurium 균수는 모두 3.3 × 106 CFU/mL이었다. 훈증소독제의 살균효과 시험에서는, 훈증소독제를 처리한 담체의 S. Typhimurium의 감소 균수는 5.22 log CFU/mL로 나타났다. 이상의 결과로부터, paraformaldehyde를 주성분으로 하는 훈증소독제는 S. Typhimurium에 대해 효과적인 살균력을 갖는 것으로 확인되었으며, 병원성 세균에 오염된 식품재료 및 주방용품의 소독에 적용할 수 있을 것으로 사료된다.

In this study, the virucidal efficacy of a fumigant (35% paraformaldehyde) against avian influenza virus (AIV) was examined. After AIV suspensions had been deposited on stainless steel carriers, the dried carriers were exposed to the fumigant in a 300-m3 test room for 3 h. Thereafter, all carriers were submerged in a neutralizing solution to scrape off the surviving viruses, and the respective suspensions were diluted. Each dilution factor was respectively inoculated into the allantoic membrane of five 10-day-old embryos. After incubation, AIV viability in the collected allantoic fluids was examined and the EID50 was calculated. The fumigant inactivated ≥5.7log10EID50 of AIV and was nontoxic to the embryos.

Recent studies have shown that during the playing of violent online games, it is not increased aggression but rather alleviation in aggression that is critical in determining whether playing gaming has positive outcomes on the venting of aggression. Drawing from the aggression catharsis perspective and gaming research, we extend this line of investigation by exploring whether gaming results in a decrease in aggression, across a wide variety of games. Using data from a survey of 771 online game users in Korea, we examined the associations among Therapeutic Catharsis Seeking, Game Self-Efficacy, Big Five Personality Traits, Game genre (violent or nonviolent), Daily online gaming time, and Demographic variables. Results showed that therapeutic catharsis seeking and game self-efficacy decreased user aggression. Neuroticism negatively affected aggression while agreeableness enhanced the degree of aggression regardless of game genre. These findings have important implications for the use of gaming as a mood management tool.

Five reading steps of reading strategy were instructed associated with skill practices, annotating, note-taking and summary outlining. A total of 23 students in a college academic reading class participated in the study. Students’ self-selected academic reading materials were used for the course. Reading self-efficacy survey and the academic reading part of IELTS practice test were conducted before and after the instruction. Student products such as annotated texts and reaction writing as well as portfolios were collected and analyzed. The survey and academic reading test results indicated that the learners’ reading self-efficacy and their reading ability were improved and that the students seemed to have gained more confidence in academic reading.

Malassezia pachydermatis (M. pachydermatis) otitis is an important infectious disease of dogs throughout the world. In the present study, the presence, diagnosis, clinical signs and chemotherapy of M. pachydermatis were studied in clinical otitic dogs of Lahore and its suburbs. During two-year study period, a total of 200 ear cerumen samples from otitic dogs were examined microscopically. Of these, 46 (23%) were found positive for M. pachydermatis. The difference in the prevalence of infection between the pendulous ear and erected ear dogs as well as sex predilection was found nonsignificant (P>0.05). However, a significantly (P<0.05) higher prevalence (86.90%) was recorded in dogs of more than one years of age group. The animals determined positive for the M. pachydermatis were divided into two groups (A and B) and treated with Clotrimazole and Nystatin, respectively. Efficacy of both the antifungals was evaluated on the basis of reversal of clinical signs scoring and cytological examinations at 7, 14, 21-day post treatment. The overall efficacy of Clotrimazole and Nystatin was 73% and 68%, respectively. Clotrimazole showed better results as compared to Nystatin in accomplishing cure rate from mycological infection. It was concluded that M. pachydermatis is a significant cause of otitis in dogs wherein Clotrimazole proves to be a more effective drug in eliminating the infection in the affected Dogs.

The present study investigated which facets of perceived self-efficacy (PSE) in L2 reading are significantly related to L2 reading proficiency (L2RP), which type of linguistic knowledge feeds into PSE, and how they are related to L2RP when considered together. Participants (n = 95) were college students from two universities in Seoul. Four subcomponents of PSE were identified for investigation: text-based PSE, general PSE, PSE in linguistic knowledge, and PSE in authentic reading. The result of stepwise multiple regression analysis showed that the general PSE whose items reflect dimensions of social comparative influences and perceived controllability over environments was the only significant predictor of L2RP (R2 = 17.7%). For the relationships between linguistic knowledge and PSE, vocabulary knowledge (VK) was shown to be the only significant predictor of PSE when considered together with grammar knowledge (GK) and L2RP (R2 = 22.9%), while VK and GK were significant predictors of L2RP (R2 = 69.4%). PSE was not found to make an independent contribution to L2RP when considered with linguistic knowledge.

Recently, increased caffeine intake has led to an increase in caffeine addiction and withdrawal symptoms. Coffee is surreptitiously consumed in as an additive to milk and caramel. There are few studies on how coffee affects the health of modern people. The purpose of this study is to determine the efficacy and side effects of coffee by awareness of coffee consumption patterns among college students, who are the principal consumers. A survey was conducted from May 11 to 17, 2015 and 302 questionnaires were analyzed. The respondents were 140 men (46.4%) and 162 women (53.6%). In terms of coffee additives, 151 (50.0%) respondents chose ‘americano’ and 111 (36.8%) ‘variation’. The frequency of coffee intake and sleep time for college students was negatively correlated, with the correlation coefficient of －0.145 and significance probability of 0.019. The group that was ‘positively’ aware of the principal ingredients of coffee had a higher level of academic training than those with ‘negative’ awareness (p=0.000). Women recognized a larger number of side effects than men: 1.99 and 1.36, respectively, on average (p=0.001). ‘Time for consumption’ had statistically significant effects on the side effects of coffee consumption: consumption before/after lunch, before/after supper and before going to bed led to 0.4 times (p=0.048) and 0.3 times (p=0.023) more side effects, respectively, than consuming coffee after getting up and before/ after breakfast. Excessive caffeine intake through coffee led to limited sleep time and poorer learning concentration. The guidelines for proper coffee consumption should be created to help students consume coffee properly so that it will not affect sleep, learning concentration or adversely affect health.

Various insect pests and plant disease can outbreak in a field. For the effective control of pests and plant diseases during crop cultivation, farmers simultaneously or sequentially spray various eco-friendly agricultural materials (EFAM), chemical pesticides and microbial control agents on the same fields. It was reported that many agrochemicals are harmful to entomopathogenic fungi, especially some fungicides with broad spectrum activity that are routinely applied for the control of plant diseases. In addition, some pesticides may antagonize the potential insecticidal activity and efficiency of entomopathogenic fungi. Therefore, sometimes the utilization of fungal entomopathogen in forestry and agricultural production is limited because of the undesirable interference from some fungicides and pesticides. There is little research that examines the compatibility of these EFAMs with entomopathogenic fungi and the influence of EFAMs on the control efficacy of mycopesticides. We conducted a study of influence of pretreated eco-friendly agricultural materials on control efficacy of Isaria javanica isolate against sweet potato whitefly.

A mycoinsecticide, Beauveria bassiana (strain GHA) marketed as BotaniGard® ES, was evaluated as a biological control agent against Riptortus pedestris (Fabricius) (Hemiptera: Alydidae) a major soybean pest. It was tested on commercial soybean fields with one time spray of both high (1×109) and medium (1×108spore/ml) concentration and double spray of the medium concentration. Nymph population decreased in all treated fields regardless of dose and frequency of spray. But, adult and egg populations were not affected. Alive nymphs collected from the fields and kept in laboratory showed infection rate ranging 35-68% in treated plots while 0% in control plots. It also reduced damage on soybean pods and seeds by 17.7-21.2 and 18.0-22.5% compare to control, respectively. Additionally, B. bassiana reduced other pests found in soybean fields including brown marmorated stink bug Halyomorpha halys (Stål) and two striped leaf beetle Medythia nigrobilineata Motschulsky. Also there was no negative effect on the parasitism of released non-viable eggs of R. pedestris. These results suggest that, in field condition, one time spraying of B. bassiana in the concentration of 1×108spore/ml can help reducing crop damage as well as R. pedestris nymph population.

The purpose of this study is to explore the effects of mobilization of C0-C1 and C7-T1 applied to asymptomatic individuals with reduced upper cervical rotation during the FRT. Design: parallel randomized controlled trial. 48 subjects(38.52 years±15.13) with C1-C2 rotation hypomobility in TFR joined the study and were randomized into three groups(C0, C7, control group). FRT in both directions was measured before and after the intervention. C0 intervention consisted of a dorsal translatoric mobilization of C0-C1 in the cervical neutral position. C7 intervention consisted of a ventral cranial translatoric mobilization of C7- T1 in neutral position and the control group maintained a supine position. C0 group experienced a FRT ROM to the restricted side increase of 17.64。(SD=4.55), that was significantly greater (P<0.001) than 5.95。 (SD=4.81) of the C7 group and 2.45。(SD=5.05) of the control group. The results showed that a dorsal translatoric mobilization of C0-C1 in neutral position restored the physiological FRT mobility in subjects with C1-C2 hypomobility and experienced statistical significant improvement in FRT as compared to a C7-T1 translatoric mobilization and a control group. (Level of evidence: 1b).

기후변화에 따른 해충개체군 증감모형은 해충방제를 위 한 초발생예찰과 연속적 해충변동 양상의 파악에 매우 중 요하다. 이러한 예측은 농약사용의 효율성을 높이고, 환경 에 적은 영향을 줄 수 있으므로, 현대 해충방제전략의 화두 로 볼 수 있다. 본 연구는 온도변화에 따른 해충의 농약효과 에 따른 사충률의 변화를 개체군 모형과 결합시켜 모의했다. 감수성 점박이응애를 강낭콩을 기주로 20, 25, 30, 35℃에서 Acrinathrin-Spiromesifen 혼합제와 Azocyclotin 유기주석계 농약에 노출시켰다. 생물검정 결과 점박이응애의 사충률은 온도와 농약의 종류에 따라 유의한 차이가 발생했다. 점박이 응애의 개체군 밀도변동 모의는 DYMEX를 이용했으며, 모 의결과 농약의 종류별로 기후변화에 따른 초기방제 시기와 방제횟수에 차이가 나타날 것으로 예측됐다. 본 연구결과는 미래의 기후변화에 대응한 해충방제 전략과 농약 선발에 있 어 중요한 시사점을 제공할 것으로 사료된다.

This study analyzed the impact of sense of self-efficacy on job satisfaction and organizational commitment among technical designers in order to acquire information needed for human resources management in the field of technical design. The study was implemented through a normative-descriptive survey method using a questionnaire. The sample consisted of 217 technical designers working at vendors and agents located in Seoul. The results revealed that there were significant differences in the sense of self-efficacy levels among technical designers according to age and work experience. Personal self-efficacy had a positive influence on both intrinsic and extrinsic job satisfaction, but also on affective, continuance, and normative organizational commitment. In addition, personal self-efficacy had a greater influence on extrinsic job satisfaction than social self-efficacy. Both personal and social self-efficacy influenced continuance commitment while there was no relationship between social self-efficacy and affective organizational commitment. However, a clear relationship was found between both social and personal self-efficacy and normative organizational commitment. Nevertheless, social self-efficacy had a greater influence on normative organizational commitment than personal self-efficacy. This fact demonstrates the need to exert more effort to promote the sense of personal self-efficacy of technical designers. These results could be used to provide appropriate proposals for human resources management in the field of technical design.

The purpose of this study was to determine the relationship between children’s dietary self-efficacy, general characteristics and mother’s parenting self-efficacy among elementary school students. Mother’s parenting self-efficacy was significantly higher as parents’ educational levels increased (p<0.001), as family monthly income level increased (p<0.001), and when father’s job was professional or managing work (p<0.001). Children’s dietary self-efficacy was meaningfully higher when parents’ educational levels were higher (p<0.01), and family income level was higher (p<0.01). Mother’s parenting selfefficacy showed a correlation with children’s dietary self-efficacy (p<0.001). All factors comprising parenting self-efficacy, such as ‘general parenting self-efficacy’ (p<0.001), ‘healthy parenting self-efficacy’ (p<0.001), ‘communication parenting self-efficacy’ (p<0.001), ‘educational parenting self-efficacy’ (p<0.001), and ‘control parenting self-efficacy’ (p<0.001) showed correlation with children’s dietary self-efficacy. It is suggested that in order to improve children’s dietary self-efficacy and mothers’ parenting self-efficacy, families, schools, and communities must put forth a concerted effort. By complementing existing nutritional programs focusing on nutritional knowledge, one can develop a education program and social support to enhance children’s dietary self-efficacy and mothers’ parenting self-efficacy.

영지버섯과 상황버섯의 항당뇨 효능을 알아보기 위하여 실험을 수행하였으며, 당뇨병에 negative regulator로 작용 하는 PTP1B의 억제 활성을 살펴본 결과 영지버섯과 상황 버섯이 억제 활성을 보였으며, 타액의 α-amylase는 타액 과 췌장내에서 탄수화물의 소화에 있어서 중요한 효소로 작용하며 이 효소를 저해시킴으로서 탄수화물의 소화 속 도를 지연시켜 식후 혈당 상승을 억제할 수 있다. α- amylase 억제활성정도를 실험으로 확인한 결과 양성대조 구와 비슷한 억제활성을 보였으며, 상황버섯은 89%로 Acarbose와 같은 억제 활성을 보였다. α-glucosidase는 다 당류의 탄수화물을 단당류로 분해하는 탄수화물의 소화와 흡수에 필수적인 효소로 억제활성을 실험으로 확인한 결 과 양성대조구와는 다르게 낮은 억제 활성을 보였다. 두 가지 소화효소에 모두 억제활성을 보이는 기존제품의 단 점을 보완할 수 있을 것으로 생각된다.

본 연구의 목적은 청소년을 대상으로 자기주도학습 코칭프로그램을 적용하여 학업적 자기 효능감에 어떠한 영향을 미치는지 알아보고자 하였다. 연구문제는 첫째, 청소년을 위한 자기주 도학습 코칭프로그램의 구성은 어떠한가? 둘째, 청소년을 위한 자기주도학습 코칭프로그램이 학업적 자기효능감에 미치는 효과는 어떠한가? 이다. 도미향(2014) CPA 코칭 모델과 코칭 대 화모델을 적용하여 자기주도학습 코칭프로그램을 구성하였으며, I.C에 위치한 00학원의 예비 중학생 54명 중 27명은 실험집단으로, 27명은 통제집단으로 선정하여 주 2회 자기주도학습 코 칭프로그램을 70분씩 총 12회기로 진행 후 사전, 사후검사를 실시하였다. 그 결과 첫째, 자기주 도학습 코칭프로그램을 적용한 실험집단의 학업적 자기효능감이 유의미하게 높아졌다. 둘째, 실험집단의 과제난이도 선호와 자기조절 효능감은 유의한 차이가 있었으나, 자신감은 실험 전 과 후의 차이가 나타나지 않았다. 자기주도학습 코칭프로그램을 통하여 학습을 새롭게 보는 시각이 생겼고, 자신의 변화를 느끼고 체험했기 때문에 적극적으로 학습활동에 참여할 수 있 는 원동력이 되었다는 부분이 학업적 자기효능감에 긍정적인 효과를 미친다는 것을 알 수 있 었다.
