Nepal is a small country (147,181㎢) located in a borderline between two bio-geographical regions, Palearctic in the north and Oriental in the south. It has wide altitudinal variation from flat plain to high Himalaya (60-8848m). Due to the unique climatic and geographical variations, it is rich in biodiversity. Altogether 211 species of mammals, 878 species of birds, 182 species of herpeto-fauna and 232 species of fishes have been recorded in Nepal. Mammalian species occupied the 4.2% species of all mammals of the world. All together 46 species of mammals are listed under the categories of threatened IUCN threatened category including one regionally extinct, eight critically endangered and 25 endangered species. Small mammals have significant part (71.6%) in total mammalian species of Nepal. It occupies 151 species under seven orders and 25 families. Two species of small mammals Himalayan Field Mouse (Apedoemus gurkha) and Mouse-eared Myotis (Myotis csorbai) are endemic to Nepal. Among the small mammals (for example, rodents) occupied the highest number (52 spp.) and Chiroptera occupies the second position (51 spp.). Field-collection and observation of small mammals has been done three times since December, 2014 to February, 2016 in three different locations Kathmandu (1,200-1,800m), Pokhara (827-2,600m) and Lumbini (65-2,000m) of Nepal. Live-traps (Sherman trap) and traditional mouse-catching live-traps in different size were used to collect small mammals. A total of 221 individuals were captured from different habitats, human settlement (129 individuals), grassland (46 individuals), forest (25 individuals) and agriculture land (21 individuals). 99 individuals were collected from Lumbini following by 83 individuals from Pokhara and 39 individuals from Kathmandu. Morphological measurement has done in each species and their biological samples were collected. Altogether, four orders, four families and 19 species of small mammals were collected and identified. In addition, three species of monkey (Macaca assamensis, Macaca mulata and Semnopithecus schistaceus) and one species of flying fox (Pteropus giganteus) were observed in their natural habitats. A total of eleven taxa of Muridae family (Bandicota bengalensis, Canomys Badius, Mus booduga, Mus musculus, Niviventer fulvescen, Rattus nitidus, Rattus norvegicus, Rattus pyctoris, Rattus rattus, Rattus tanezumi, and Tatera indica) were identified within species level but three taxa were identified within genus level (Mus spp., Niviventer spp. and Rattus spp.). Among the collections, Rattus rattus was most dominant (33.93%) and Suncus murinus (20.81%) as well as Mus musculus (12.21%) occupied second and third position, respectively. Rattus rattus, Rattus tanezumi, Rattus norvegicus and Suncus murinus were abundant in all habitats but Rattus pyctoris, Canomys badius and Tatera indica only found in wild habitats, grassland and forest. In this study Canomys badius, Niviventer fulvescen, Tatera indica and Semnopithecus schistaceus are truly wild species but remaining 19 species are urban species. This study shows that large numbers of small mammals are urban type and their habitat is associated with human beings. For more clear understanding the ecological roles of Nepalese small mammals found, further continious monitoring and comprehensive studies are required to obtain abundant information applicable to comparative analyses of intraand inter-species interaction in the wild and urban habitats of Nepal.

본 연구는 2005년과 2007년에 시행한 중소기업기술통계조사에 모두 응한 중소 기업 중 전자부품, 영상, 음향, 통신 장비 업체(KSIC 32) 142개사를 대상으로 외부 자원 활용 과 흡수능력이 2년 후 경영성과와 혁신성과에 어떠한 영향을 미치는지, 또한 흡수능력이 이 들 관계를 어떻게 조절하는지를 실증 분석하였다. 분석 결과, 공동기술개발 여부와 정부지원액으로 측정한 외부 자원 활용은 성과에 유의미 한 영향을 미치지 않았고, 매출액에 대해서만 R&D투자비는 정(+)의, R&D인력비는 부(-)의 영향을 끼쳤다. 그리고 흡수능력의 조절효과는 측정방식과 독립변수에 따라 다르게 나타났 다. 즉, 공동기술개발을 수행할 때의 성과는 R&D투자비가 증가할수록 향상했지만, R&D인 력비는 반대로 작용했다. 그리고 정부의 자금지원이 늘어날수록 성과가 향상하는 기업은 R&D투자비가 낮거나 R&D인력비가 높은 기업이었다. 이러한 연구 결과는 중소기업의 외부 자원 활용이 내부 역량을 대체하지 못하며 오히려 흡수능력을 축적하여 외부 자원 활용의 효과를 극대화 할 필요가 있음을 보여준다. 또한, 공 동기술개발을 수행할 때에는 중소기업의 적극적인 R&D투자가 필요하며 정부의 자금지원은 R&D인력을 보유하고 있으나 자금을 확보하지 못해 독자적인 기술개발이 어려운 기업에 더 욱 효과적이다. 본 연구는 제한된 산업과 표본에서 이루어진 한계가 있지만, 종단적 자료를 통해 인과관계를 규명함으로써 기존 연구들의 한계를 극복하였다.

An acoustic and trawl pilot survey using a small vessel was conducted in Jinhae bay of the South Sea of South Korea on April 13~14, May 11~13 and June 8~10, 2015. During the survey, acoustic data was collected and bottom trawls were conducted at the same time. First, various noises were eliminated by using the Park method based on the Wang method(Wang et al., 2015; Park et al., 2015), the species compositions and catch rate from each bottom trawl were observed, and spatial distribution of fishery resources in the water column and their nautical area scattering coefficient (NASC) were investigated through acoustic data. During the entire survey period, 12 orders, 33 families and 41 species were caught. The most caught species in April, May and June were Okamejei kenojei, Zoarces gilli and Pholis nebulosa, respectively. Fish schools were observed near the line of net mouth height in April. Numerous weak scatters were presented on the echograms in May and June. Many fish schools appeared in between the water surface and 20 m deep in May. The NASC value from entire water columns was the lowest in April (35.9 m2/n･mile2) and highest in June (1541.3 m2/n･mile2).

본 연구는 소형 고속정의 운항한계를 검토하기 위하여 수행되었다. 일반적으로 내항성능의 검토는 선형의 결정 단계 전에 이루어지지만 본 연구는 선박의 건조가 완료된 후에 이루어졌다. 검토 결과, 종동요, 수직 및 수평가속도, 슬래밍의 운동성능은 특정한 조우각을 제외하고는 만족하였으나 갑판침수의 경우에는 해석을 수행한 모든 조건에서 만족하지 않았다. 이것은 대상선박의 크기가 소형이기 때문에 선박의 속도나 파도와의 조우각보다는 해상상태가 설정한 내항성능 기준의 만족 여부에 더 큰 영향을 미쳤기 때문으로 보인다.

Yield per recruit model is the most popular method for fisheries stock assessment. However, stock assessment using yield per recruit model can lead to recruitment overfishing as this model only considers the maximum yield per recruit without spawning biomass for reproduction. For this reason, spawning biomass per recruit model which reveals variations of spawning stock biomass per fishing mortality (F) and age at first capture (tc) is considered as more proper method for stock assessment. There are mainly two methods for spawning biomass per recruit model known as age specific selectivity method and knife– edged selectivity method. In the knife–edged selectivity method, the spawning biomass per recruit has been often calculated using biomass per recruit value by multiplying the maturity ratio of the recruited age. But the maturity ratio in the previous method was not considered properly in previous studies. Therefore, a new method of the knife–edged selectivity model was suggested in this study using a weighted average of the maturity ratio for ages from the first capture to the lifespan. The optimum fishing mortality in terms of F35% which was obtained from the new method was compared to the old method for small yellow croaker stock in Korea. The value of F35% using the new knife–edged selectivity model was 0.302/year and the value using the old model was 0.349/year. However, the value of F35% using the age specific selectivity model was estimated as 0.320/year which was closer to the value from the new knife–edged selectivity model.

Life cycles of Sweltsa illiesi and S. lepnevae were determined from a headwater stream in Mt. Jumbong. Identification of nymphs was done by using DNA barcoding. Nymphs begin to have species specific color pattern on their head several months prior to adult emergence and differ in the form of the third antennal segment. Two species appear to have similar semivoltine life cycles in this stream, beginning to hatch from June and finishing adult emergence about 701 days later. The combined annual mean biomass in ash free dry mass (AFDM) was estimated as 96 mg AFDM m-2. The combined annual secondary production were 373 mg and 297 mg AFDM m-2 yr-1, calculated by using size frequency method and increment summation method respectively.

Many enterprises have been adopting management systems good enough for them and operating the schemes to have competitive edge better than their competitor. One of the finest systems that most companies have been selecting is ISO 14001. ISO 14001, environment management system, is widely known as advancing internal efficiency and productivity in the various industries. As a result, the number of companies that have adopted ISO 14001’s certification have been increasing continuously year by year since ISO 14000 standard was called in 1994s from ISO 18000 standard that originally used. The purpose of this study is to present that ISO 14001’s requirement execution influences on management performance in the small manufacturer. In order to carry out this research, we obtained 96 survey sheets and inspected ten assumptions based on the reliability, validity of the questionnaires. The results of regression analysis are summarized as follows; First, the three factors of ISO 14001 requirement, plan, implementation and operation and management consideration, have an important effect on the operational performance. Second, the three elements of ISO 14001 requirement, environment policy, implementation and operation and management consideration, affect to the financial performance significantly. Based on the results, it is sure that the companies that execute the factors of implementation and operation and management policy have a good performance to achieve operational and financial performance so that it is important to clarify the member’s role, authority and follow the procedure by a company’s process. Also, the truth shows CEO’s continuous will and periodical review of ISO 14001 influence on management performance as well.

ISO 9001, quality management system, is widely known as advancing internal efficiency and productivity in various industry. As a result, the number of companies that have adopted ISO 9001’s certification have been increasing continuously year by year since ISO 9000’ family standard was published in 1987s. This fact shows that a lot of businesses are trying to get the accreditation for improving the competitiveness of quality. The purpose of this study is to present that ISO 9001’s certification motives affect to the requirement’s implementation and show that the execution of requirements influences on management performance in the small manufacturer. In order to carry out this research, we obtained 96 survey sheets and inspected twenty assumptions based on the reliability, validity of the questionnaires. The results of regression analysis are summarized as follows; First, the factors of certification motive influence on the requirement’s implementation except resources management. Second, the two elements of ISO 9001 requirement, resources management and product realization, have an important effect on the operational performance and financial performance considerably in the companies that choose the internal motive. Finally, the two requisites of ISO 9001 requirement, resources management and measurement, analysis and improvement, affect to the operational performance and financial performance significantly in the businesses that select the external motive. Based on the results, the companies that choose the internal motive have a good performance to execute the ISO 9001 requirements. Also, to implement the requirements of ISO 9001 is helpful for the companies to produce the operational and financial performance.

This study investigated the potential associations of dog characteristics with serum serotonin (5HT) concentration in dogs with degenerative mitral valve disease (DMVD). Client-owned dogs were prospectively recruited at the Veterinary Medical Teaching Hospital of Chungnam National University between 2010 and 2011. Forty-two dogs (22 females and 20 males) were enrolled in this study. DMVD dogs included Maltese (n=12), followed by Shih-tzu (n=10), mixed breed (n=5), Chihuahua (n=4), Miniature schnauzer (n=3), Miniature poodle (n=3), Miniature pinscher (n=1), Pomeranian (n=1), Yorkshire terrier (n=2), and Spitz (n=1). As inclusion criteria for the study, dogs had to show either direct or echocardiographic evidence of DMVD. Platelet count significantly differed among the three groups, as the moderate (P<0.05) and severe groups (P<0.05) showed significantly higher platelet counts than the mild DMVD group. Additionally, significantly higher LVIDd, LVIDs, fractional shortening (FS), and LA:Ao ratios were observed in dogs with moderate (P<0.05) and severe (P<0.05) DMVD compared to the mild group, respectively. Significant positive correlations between serum 5-hydroxytryptamine (5HT) concentration and platelet count (r=0.273, P=0.03), LA:Ao ratio (r=0.459, P=0.001), and LVIDd (r=0.319, P=0.013) were observed in DMVD dogs. Therefore, serum 5HT concentration may be a potential cause of DMVD progression.

신체크기는 다양한 동물그룹에서 짝짓기의 성공을 결정짓는 중요한 요소로 알려져 있다. 그럼에도 불구하고, 한국산 유미양서류의 짝짓기 경쟁에 있어 수컷도롱뇽들의 신체크기가 어떻게 영향을 미치는 지는 연구가 잘 수행되어 있지 않다. 우리는 한국 고유종으로 짝짓기 행동이 알려져 있지 않은 고리도롱뇽(Hynobius yangi)을 이용하여, 큰 고리도롱 뇽 수컷이 작은 수컷에 비하여 짝짓기 경쟁에서 우세한지 여부를 연구하였다. 큰 수컷, 작은 수컷, 암컷 각 한 마리를 그룹으로 수행된 짝짓기 행동을 암컷에 대한 구애행동, 수컷간 경쟁행동, 알의 수정행동으로 구분하여 분석한 결과, 큰 수컷과 작은 수컷 사이의 구애, 경쟁, 수정행동 어느 것에서도 통계적으로 유의한 차이를 보이지 않았다. 이러한 결과는 아마도 고리도롱뇽 수컷들 간 크기 변이 정도가 작으며, 암컷이 알을 산란할 장소가 서식처 내에 풍부함에 기인한 것으로 판단된다. 이 연구는 고리도롱뇽의 짝짓기 행동에 관한 첫 번째 보고이다.

Large spatial structures can not easily predict the dynamic behavior due to the lack of construction and design practices. The spatial structures are generally analyzed through the numerical simulation and experimental test in order to investigate the seismic response of large spatial structures. In the case of analysis for seismic response of large spatial structure, the many studies by the numerical analysis was carried out, researches by the shaking table test are very rare. In this study, a shaking table test of a small-scale arch structure was conducted and the dynamic characteristics of arch structure are analyzed. And the dynamic characteristics of arch structures are investigated according to the various column cross-section and length. It is found that the natural vibration periods of the small-scaled arch structure that have large column stiffness are very similar to the natural vibration period of the non-column arch structure. And in case of arch structure with large column stiffness, primary natural frequency period by numerical analysis is very similar to the primary natural frequency period of by shaking table test. These are because the dynamic characteristics of the roof structure are affected by the column stiffness of the spatial structure.

애멸구(Laodelphax striatellus)는 rice stripe virus (RSV)의 매개충으로 벼에 큰 피해를 주는 해충이다. 본 연구에서는 애멸구의 장·단시형, 암·수, 약·성충에 대한 RSV 보독률과 이병률을 비교하였다. 애멸구의 장·단시형의 RSV 보독률은 각각 60.7%, 63.1%로 크게 차이는 없었다. 암·수에 대한 RSV 보독률은 각각 61.9%, 52.2%로 암컷의 보독률이 더 높았으나 유의성은 없었다. 약·성충의 보독률을 비교한 결과 각각 51.2%, 58.7%로 역시 크게 차이가 나지는 않았다. RSV에 감염된 애멸구에 노출된 건전한 벼의 이병률은 장시형은 53.3%, 단시형은 48.2%를 보였으며, 약·성충의 이병률은 각각 38.2%, 42.6%를 보여 유의성은 없었다. 반면 암컷은 50.5%의 이병률을 보이고 수컷은 22.3%의 이병률을 보여 암컷이 수컷에 비해 22.3% 이병률이 높아 유의성이 있었다. 또한 벼와 애멸구의 RSV 감염여부에 의한 애멸구의 발육기간은 건전한 벼에 RSV 감염 애멸구를 접종 했을 때 가장 긴 것으로 나타났으며, 건전한 벼에 건전한 애멸구를 접종 했을 때 발육기간이 가장 짧은 것으로 나타났다.
