Understanding climate change is not only complex but also extensive. Humanity has never embarked on such a huge challenge of trans-national scope: a problem that began in the past continues now and will be continuing for a long time in the future. Nepalese have also significantly felt the impact of global climate change. The scenarios of climate change indicate that the increased temperatures will cause snow-melt which will result in floods, droughts, and uneven weather patterns. The impact of such unexpected climate hazards and weather patterns have already been felt and will continue to be felt in Nepal. These climate change-induced hazards and risks particularly threaten the agriculture sector, which results in food insecurity and makes poor and vulnerable people face increasingly unanticipated impacts to their lives and wellbeing. This paper explores the climate vulnerability of the Nepalese in terms of their physical, social, economic and primarily agricultural losses due to the increasing impact of climate change. The paper argues the need for a timely adaptation of measures to maintain an environment suitable for agriculture and for the well-being of the population residing in the area.

얼굴 자극의 성별 및 종족과 라인업 절차에 따른 얼굴 인식에서의 차이를 알아보기 위해 두 편의 실험을 수행하였다. 실험 1에서 사용된 자극은 동남아시아인 및 동북아시아인 남성의 정면 얼굴 이미지였으며 얼굴 자극의 종족과 실험참가자의 종족이 동일할 때 얼굴 인식이 향상될 수 있는지(동종족 우세 효과)를 알아보았다. 실험 2에서는 동북아시아인 남성 및 여성의 정면 얼굴을 자극으로 사용하여 참가자와 얼굴 자극의 성별이 같을 때 얼굴 인식이 더 정확한지(동성별 우세효과) 알아보았다. 두 실험에서 실험참가자는 모두 동북아시아인이었으며 라인업 절차의 동시제시 조건과 순차제시 조건을 사용하여 얼굴 자극 제시 방법에 따른 차이도 비교하였다. 실험결과 동종족 우세 효과와 라인업 절차에 따른 얼굴 인식 정확도의 차이는 관찰되지 않았으나 표적이 동남아시아인 자극일 때 얼굴 인식 정확률이 높았다. 흥미롭게도, 동성별 우세 효과는 여성 실험참가자에 한해 관찰되었다. 이러한 결과를 통해 얼굴 인식이 주의에 의해 영향을 받을 수 있을 가능성에 대해 논의하였다.

본 연구에서는 도시와 농ㆍ어촌 아동들의 가족건강성과 자아탄력성에 의한 학교생활 만족도에 대해 비교 분석을 중심으로 두 지역간의 차이를 검증하고 이에 관련된 변인들을 규명하였다. 또한 아동의 가족건강성과 자아탄력성이 학교생활 만족도에 미치는 영향에 대해 분석해 보았다. 좀 더 나아가 지역적 요소를 변인으로 넣어 도시와 농ㆍ어촌 지역의 아동들의 학교생활 만족도를 비교 분석하여 환경적인 측면이 아동들에게 어떻게 영향을 미치는지 대해서도 알아보았다. 지역적으로 비교분석을 하기 전에 아동의 가족건강성과 자아탄력성, 학교생활 만족도, 즉 독립변인과 종속변인의 상관관계를 분석한 결과 가족건강성과 자아탄력성, 가족건강성과 학교생활만족도, 자아탄력성과 학교생활만족도 간에 통계적으로 유의미한 정적 상관이 있는 것으로 나타났다. 이것은 어떠한 변인보다 가족건강성과 자아탄력성이 학교생활 만족도에 영향을 미친다는 결과라고 볼 수 있다. 이 연구의 의의와 그 시사점을 논하고 제언을 제시하였다.

Recently, the pedestrian protection regulations of Europe and Japan are becoming more stringent. However, it is difficult to evaluate the performance of protection because each regulation has different test conditions such as dummy, impact speed and so on

This survey focused on consumer's consumption patterns for buying factors of domestic live stock products after foot and mouth disease (FMD). The purpose of this survey was to suggest basic information to reduce consumption when livestock diseases are occurred. Two methods were used for this survey. First method was to investigate internal data to understand consumption patterns when buying domestic livestock products. Second method included empirical analysis to understand how FMD affected consumer's consumption pattern. Survey was conducted in Chuncheon city. As the result of this survey, factors that affected the buying patterns of domestic livestock products were brand and expiration date. These results suggested that consumers recognized brand livestock products were safer than general livestock products and they have more interest for food safety than quality attributes of food when buying domestic livestock products.

This study investigated refinement behaviors of TiC powders produced under different impact energy conditions using a mechanical milling process. The initial coarse TiC powders with an average diameter of 9.3 were milled for 5, 20, 60 and 120 mins through the conventional low energy mechanical milling (LEMM, 22G) and specially designed high energy mechanical milling (HEMM, 65G). TiC powders with angular shape became spherical one and their sizes decreased as the milling time increased, irrespective of milling energy. Based upon the FE-SEM and BET results of milled powders, it was found initial coarse TiC powders readily became much finer near 100 nm within 60 min under HEMM, while their sizes were over 200 nm under LEMM, despite the long milling time of up to 120 min. Particularly, ultra-fine TiC powders with an average diameter of 77 nm were fabricated within 60 min in the presence of toluene under HEMM.

The advancement in technology and availability of Computer Mediated Communication (CMC) technology and the Internet made meaningful interaction possible in both on and offline environments, which is referred to as blended learning. Blended learning has recently begun to gain popularity in ELT, and appropriate models of blended learning need to be developed for EFL classrooms. However, there have not been many attempts to investigate its application and development of appropriate teaching and learning models of blended learning in the field of ELT, especially in relation to English language skills and subskills. Therefore, the purposes of this study are to investigate the students’ perspectives and effectiveness of blended learning in English pronunciation skills, and to explore gender differences in blended learning. The subjects of this study consist of 173 Korean university students, and quantitative data including questionnaire and pre-experiment were collected. The major findings of the study are as follows. First, students’ perspectives in blended learning, its components, and tools were very positive. Second, blended learning was found to be effective in the development of segmental and suprasegmental pronunciation skills. Third, there were few significant gender differences found regarding social aspects of online interaction. Implications and suggestions based on the findings and discussion are provided.

청소년들의 학습, 일, 수면, 기타 필수적인 것에 소요된 시간을 제외한 교제 및 여가활동을 위한 기준시간은 통계청의 자료에 의하면 1일 평균 4시간 45분으로 나타나고 있다. 급격한 정보화가 진행되면서 청소년들의 여가활동은 TV시청 이나 컴퓨터게임 등에 편중되고 있어 정부에서는 이에 대한 부작용을 최소화하기 위해 게임셧 다운 제도까지 도입하였다. 그래서 본 연구에서는 청소년들의 취미ㆍ특기를 일반청소년과 범죄청소년간의 차이, 취미ㆍ특기별 성격유형이 범 죄에 미치는 영향, 범죄청소년과 취미ㆍ특기별 성격유형을 비교분석하였다. 범 죄청소년은 노래부르기, 구기운동, 정적형, 당구 등 순으로 선호하고, 일반청소년은 구기운동, 노래부르기, 예술형, TV시청 등 순으로 취미ㆍ특기활동을 하는 것으로 나타났다. 그러나 전자게임ㆍ격투기ㆍ영화감상ㆍ음악감상ㆍ스포츠 등은 일반ㆍ범죄청소년 사이에 유의미한 차이가 없었다. 취미ㆍ특기종류별 성격유형 이 청소년범죄여부에 대해 스포츠형(67.9%), 독서(54.6%), 그림그리기(46.2%), 격투기(41.8%), 정적형(39.7%), 예술형(39.5%), TV시청(36.8%), 영화감상 (35.7%) 음악감상(22.6%), 구기운동(17.3%), 전자게임(13.3%), 노래부르기 (9.8%) 등 순으로 유의미한 영향을 미치는 것으로 나타났다. 범죄청소년과 취미 ㆍ특기종류별 성격유형에서는 노래부르기ㆍ격투기ㆍ당구ㆍ영화감상ㆍ정적형 등은 준법성이 낮게 나타나는 등 유사한 형태를 보이고 있다. 반면에 구기운동 ㆍ예술형ㆍ독서ㆍ스포츠형ㆍ요리 등은 준법성이 높게 나타나며 범죄청소년과 차이를 보이고 있다. 한편 전자게임과 TV시청은 범죄청소년 보다 준법성은 높으나 자아정체성, 창의성, 사교성이나 친화력, 인자함과 탐구성 등에서 범죄청소년들보다 매우 낮게 나타나고 있어 청소년의 인성발달에 부정적 영향을 준다고 볼 수 있다.

This paper examines the experiences of selected academics pioneering e-learning in Malaysian tertiary institutions. It begins with an overview of the broad factors shaping the Malaysian educational environment and then proceeds to examine the experience of individual teachers and e-learning programs. It takes an in-depth qualitative approach to engaging with this case study material drawing heavily on semi-structured interviews with key actors. Conversations with several respondents suggested that the social networks of mentor relations found in the Malaysian case studies might be aptly described as ‘bamboo networks’. Bamboo, which happens to be plentiful in the Malaysian peninsula where these case studies are based, spreads from clump to clump through a series of underground connections involving a mature clump of bamboo sending out a subterranean runner, often over very long distances that then emerge into the open as a new bamboo clump. All of those interviewed reported that they have found it difficult to find a support base in their first years of pioneering online developments. Consequently, they tended to fall back on their peer networks linked to the institutions at which they had studied. Prominent individuals championing e-learning in the institutions where they teach tend to form small groups for information sharing and networking. They do look to their management for tacit ‘permission’ rather than direct encouragement. Consequently, the active promotion of e-learning in Malaysia can be described as being ‘middle-down’ rather than ‘top-down’ in nature. That is to say, it is mid-level teachers that inspire those below them to join in the development of e-learning programs. They are internally driven and strongly motivated. In time, their activity should produce new generations of locally developed e-learning experts but this has yet to take place in a substantial fashion. This study shows that both men and women ‘academic guanxi’, or peer networks, play a key role in the adoption of online technologies. Key early adopters become change-agents by inspiring a small network of their peers and via their guanxi networks. It was also discovered that motivation is not simply an individual matter but is also about groups and peer networks or communities of exchange and encouragement. In the development of e-learning in Malaysia, there is very little activity that is not linked to small clusters of developers who are tied into wider networks through personal contacts. Like clumping bamboo, whilst the local clusters tend to be easily seen, the longer-range ‘subterranean’ personal connections are generally not nearly so immediately obvious. These connections are often the product of previous mentoring relationships, including the relationships between influential teachers and their former postgraduate students. These relationships tend to work like bamboo runners: they run off in multiple directions, subterranean and unseen and then throw up new clumps that then send out fresh runners of their own.

Restaurant managers seeking to maximize revenue should look carefully at how long their tables are occupied and how much the average diner spends. This study examined the effect of the customer's party size on restaurant revenue. The dining periods were divided into 2 types (lunch vs. dinner/weekdays vs. weekends), which were combined to show the average spending per minute (SPM), to determine if the dining periods have measurable effects on the dining duration and average bill. The results show that the dining duration for dinner was much longer than that for lunch and there was no significant difference in dining duration between weekdays and weekends. On the other hand, customers in larger parties at lunch time had a higher SPM than those in smaller parties. A larger customer party size was associated with a longer dining duration for dinner and on weekdays. During all operating periods (lunch, dinner, weekdays, weekends), the party size had a significantly positive effect on the mean spending per minute. For restaurant managers, these findings suggest opportunities to increase revenue and adopt revenue management strategies.

Voltage-dependent anion channel (VDAC) is mitochondrial protein of all eukaryotes. It has been reported that VDAC is a large voltage-dependent channel, regulation of ion (including Ca2+), and transportation of various metabolites. Ca2+ is an important factor in sperm function. In our previous study, we found high frequency of VDAC2 expression in spermatozoa from low-fertility bulls. However, to date, there is limited information available on its effects on male fertility. Therefore this experiment was designed to evaluate the effects of VDAC and Ca2+ on sperm function in vitro. To achieve this, four treatment conditions were established with or without Ca2+ and VDAC inhibitor, namely, 4’-diisothiocyano-2,2’-disulfonic acid stilbene (DIDS). Spermatozoa from adult ICR were collected and released into modified Tyrode’s salt media. And then, they were incubated in the different media with or without Ca2+and DIDS for 90 min at 37℃ in 5% CO2. Intracellular pH ([pH]i) and Ca2+ ([Ca2+]i) were measured by their fluorescent indicators, 2,7-bicarboxyethyl-5,6-carboxy- fluorescein acetoxymethyl ester (BCECF- AM) and fura-2 AM, respectively. Western blot of extracted sperm proteins with an anti-phosphotyrosine antibody (pY20) was carried out to determine tyrosine phosphorylation after sperm incubation in different treatments. To evaluate the fertilizing ability after treatments, in vitro fertilization was performed. DIDS significantly decreased [Ca2+]i regardless of Ca2+. [pH]i was efficiently affected by the presence of Ca2+ and/or DIDS. However, the highest decrease of pH level was observed under the presence of DIDS and the absence of Ca2+ in culture condition. Tyrosine phosphorylated protein 1 was significantly different under all treatments. However, tyrosine phosphorylated protein 2 was not significantly different under the presence of DIDS. Fertilization rate was significantly decreased under the presence of DIDS. Blastocyst formation was significantly altered different to compare to control and each treatment group. Therefore it suggests that a voltage-dependent anion channel may involved paramount importance in regulation of male fertility.

This study presents how a professional development program (PD) of K-12 teachers affects participants' use of the earth system approach and their perceptions of using the urban environment for their science teaching and lesson unit development. This study utilized mixed methods to collect and analyze the data. Eleven urban teachers' pre-post lessons (45 lessons) were analyzed quantitatively using a lesson plan analysis tool, modified by the author, and their lesson reflections were analyzed qualitatively. The findings of this study show that the PD program influences the teachers to choose more topics and content knowledge based on the earth system approach and to assess the topics and content knowledge with more appropriate methods. Specifically, the teachers use more urban environmental factors/topics in their post lesson to teach the environmental topics of urban area. However, according to the statistical analysis of pre-and postlesson plan scores, the accuracy of the earth system knowledge that participants used in their lessons did not change significantly (p〈0.05) (Table 4), which means that the PD program did not affect the improvement of the teacher's content knowledge in earth system science. Implications of this study are discussed.

Alloys of nylon(PA6) and ethylene-propylene-diene polymer, modified with maleic anhydride(MEPDM) were prepared using a melt kneading process. This study focuses on the effects of the content of MEPDM in PA6 blend on the mechanical and thermal properties of such blends where MEPDM is the dispersed phase. Mechanical properties were examined by stress-strain measurements and impact strength test. Both impact strength of PA6/MEPDM at room temperature and at -20℃ were improved up to 400-550% with the amounts of MEPDM. However, PA6/MEPDM containing 3-5 wt% of MEPDM showed the about 700kgf/m2 of the maximum tensile strength but 8.5 % of the lowest elongation. For certain compositions of PA6 with rubbery MEPDM, the interesting reduction of elongation is caused by the reaction of the polyamide amine end groups with maleic anhydride portion in MEPDM, that provided a reinforcement in the PA6 matrix. In addition, the introduction of antistatic agent on the surface of alloys causes significant reduction of their surface electrostatic resistance.
