최근 문제가 된 국내영화“해운대”의 파일 불법 유출사건, 각종 위조상품의 밀수입 증가 등에서 볼 수 있듯이, 국내에서 지적재산권 침해 문제는 사회전반에 걸쳐 광범위하게 영향을 미치고, 피해 규모 역시 증가할 뿐 아니라 침해의 양태 역시 국제화되고 있다. 이러한 상황에서 인터넷 기술의 발전을 통한 불법복제의 증가, 민사적 구제의 어려움 등으로 인하여 형사 절차가 민사 절차 못지 않게 많이 이용되고 있다. 이와 같이 증가하는 형사 사건에 대처하기 위하여 수사기관에서는 형사적 관점에서 상표권의 효력 유무를 판단하고, 특허 전문계약직 공무원 제도의 도입, 위조상품 신고포상금제의운영, 수사기관간 공조수사, 특별사법경찰관의 지정, 범죄수익 환수제도 등 제도를 정비하고 있다. 또한 인터넷을 통한 저작권침해사범의 경우 일반인, 특히 청소년들이 별다른 죄의식 없이 저작권을 침해하고 있고, 이에 대하여 고소가 남용되고 있어 많은 사회적 문제를 야기할 뿐만 아니라 수사력 낭비의 원인이 되어 저작권 교육 조건부 기소유예제도가 도입되기도 하였다. 이와 더불어 형사처벌 범위의 제한 여부, 민사상 인적사항 획득 절차 도입 여부, ISP 업체들의 책임 제한 범위, 온라인을 통한 저작권 침해사범에 대한 관할 확정 문제 등이 추가로 해결되어야 할 과제로 남아 있다. 최근 우리나라의 문화 콘텐츠 및 각종 기술 발달로 인하여 우리나라의 지적재산권 역시 해외에서 보호되어야 할 필요성이 증가하고 있으므로, 우리나라의 형사제도 중 미비한 부분의 정비 뿐 아니라 우리나라의 지적재산권이 침해되지 않도록 국제적인 형사제도를 정비하는 데 있어서도 적극적으로 협력할 필요가 있다.

For recipe prediction of colorant proportion showing nonlinear behavior, we modeled the effects of colorant proportion of basic colors on the target colors and predicted colorant proportion necessary for making target colors. First, colorant proportion of basic colors and color information indicated by the instrument was applied by a linear model and a multi-layer perceptrons model with back-propagation learning method. However, satisfactory results were not obtained because of nonlinear property of colors. Thus, in this study the neuro-fuzzy model with merit of artificial neural networks and fuzzy systems was presented. The proposed model was trained with test data and colorant proportion was predicted. The effectiveness of the proposed model was verified by evaluation of color difference(δE).

Larvae of Monochamus saltuarius showed normal growth and development on conifers of Pinus koraiensis, P. densiflora, Abies holophylla, Larix leptolepsis, P. bungeana, and P. rigida, respectively, but the conifers influenced significantly the body weight and the survival rate of larvae. Though the larval body weights were in a wide spectrum among treatments, growth curves of them were very similar from each other, showing continuous increase from the early larval stage to about 3 months old. The body weight was decreased slightly after the feeding period of the early 3 months. The size of larvae and adults became the largest from P. bungeana fed larvae. The mid-sized ones were from P. koraiensis, P. densiflora and A. holophylla. Small ones came from L. leptolepsis and P. rigida. The larval growth was retarded without water supply. Overall survival rates from the early stage of a larva to a fertile adult were 53.6% from P. koraiensis, 51.8%, P. densiflora, 34.7%, A. holophylla, 17.8%, P. bungeana, 16.7%, L. leptolepsis, and 12.3%, P. rigida. Adults from larvae fed the 6 species of conifers, respectively, were grown into the reproductively potent adults, which laid viable eggs. A few of overwintered larvae did not pupate and remained still as a larva until the late October of the year. Data from the field survey, the head width emerged from P. koraiensis was larger than that of L. leptolepsis. The adult emergence hole in P. koraiensis was larger also. While, the size of the emergence hole was larger in the artificially innoculated log of P. koraiensis, which was kept for a larva to be with a minimized food competition and sufficient water supply, than that of the field.

Temperature is an important inorganic factor which affects on every aspect in life of phytoseiid mites in general including N. californicus in this study. Cumulative and short-term effects of temperature through different life stages (immature, mating and oviposition periods) on mating duration and total fecundity of N. californicus were investigated at temperatures of 18, 25, 30 and 350C with a photoperiod of 16L:8D. Throughout experiments, females mated once and egg production was observed until they stop oviposition.

Tetranychus evansi Baker & Pritchard occurs on solanaceous plants, and causes serious damage to various crops in Africa and Europe. Tetranychus takafujii Ehara & Ohashi was found on Solanum nigrum L. in Japan in 2001 and described as a new species in 2002. However, because T. takafujii is very similar to T. evansi in morphology, doubt has arisen about the difference between these two species, although there is no report discussing their taxonomic status. Tetranychus takafujii is specialized on solanaceous plants and it is possible that this species gets out of hand after invasion of solanaceous agricultural crops. To evaluate its potential severity as a pest, it is necessary to assess its performance on a variety of food plants in a carefully controlled laboratory set-up. The present study determined the development on 21 crops and weeds, and the reproduction on Solanum nigrum of a Japanese T. takafujii population and six T. evansi populations from abroad. Four plants (potato, horsenettle, pear and cucumber) served as host plant for all seven populations and most larvae successfully reached adulthood. Life-history parameters, such as the rate of development and the intrinsic rate of natural increase (rm), became higher with temperature increasing from 15 to 35°C. The rm-value at 25°C was similar among all populations tested and it was close to the value obtained in T. takafujii [Kotsubo et al. (2004) J. Acarol. Soc. Jpn. 13: 71-76]. This indicates that T. takafujii has the potential to become a serious pest on solanaceous crops, just the same as T. evansi in Africa and Europe.

Arsenic is a naturally occurring element in the earth's crust and is found throughout the environment, but compared with other toxic elements, little toxicological work has been conducted on arsenic. In this study, we tested the effect of two different arsenic compounds (arsenite (NaAsO2) and arsenate (Na2HAsO4)) on the reproduction of soil inhabiting collembolan species (Paronychiurus kimi). The toxicity tests for each arsenic compound were conducted in accordance with the ISO 11267. The estimated EC50s for reproduction of each arsenic compound were 20.43 (16.97-24.60) and 32.86 (25.64-42.13) mg/kg, respectively. There were statistically differences in the toxicity of two different arsenic compounds based on overlapping 95 % confidence intervals. The relative toxicity ratio of arsenite to arsenate (approx. 0.62) as well as the concentration-dependent decrease in reproduction of P. kimi was steeper at arsenite than that of arsenate. These results show that arsenite was more toxic to P. kimi than arsenate.

무당개구리(Bombina orientalis, Korean fire-bellied toad)는 양서강 개구리목 무당개구리과 무당개구리속(Class Amphinia, Order Anura, Family Bombinatoridae Genus Bombina)의 무미양서류이다. 소형으로 행동이 느리고 온순하여 취급이 용이하며 실험모델로써 많은 장점이 있으나 번식기를 제외한 개체를 대상으로 한 연구는 시료확보의 난점으로 무당개구리의 계절번식 특성에 대한 연구는

본 논문은 PDP TV에서 주위 환경을 고려한 색 재현 방법을 제안한다. 관찰자의 시공간적인 위치에 따 라 주변 환경이 변하기 때문에, 디스플레이의 색 재현 과정에서 주위 조명은 반드시 고려되어야 한다. 주변 환경을 고려하기 위한 기존의 방법은 각 채널에서 전압의 이득을 조절함으로써 계조와 포화도를 향상시키기 때문에 인간의 순응 현상을 구현하는데 한계가 있으며, 이에 따라 다양한 주위 조건하에서 인지된 색을 재현하는데 어려움이 있었다. 따라서 이를 해결하기 위해, 본 논문은 PDP의 물리적 특성인 플레어 현상을 고려하였으며, 밝기에 기반하여 특성화 과정을 수행하였다. 또한, 센서로 획득된 주위 조명의 색온도 및 밝기값의 정보를 이용하여 색 순응현상을 적용하였다. 특히 암실에서는 색순응 현상을 적용함으로써 저전력 구동이 가능하였으며, 실험을 통해 제안한 방법이 기존의 방법에 비해 시각적 평가에서 더 우수함을 확인하였다.

The purpose of this study was to determine the influence of muscle fatigue in elbow flexors on the sense of force reproduction. Fifteen healthy subjects were recruited for this study. Maximum voluntary force (MVF) of elbow flexor muscles was measured by a digital tensiometer. Force errors were measured to test accuracy of the sense of force reproduction in elbow flexors. The subject was required to flex the elbow joint, to maintain and concentrate on about 20% of the MVF target force under visual feedback for 3 seconds. After a 5 second period rest, the subject was asked to duplicate the target force actively. Muscle fatigue was evoked with isometric contraction of the elbow flexors. Isometric contraction was continued until a 50% drop in MVF. The difference, in kilogram between the target force and the reproduced force was calculated for measuring force error. Force errors were compared between the non-fatigued condition and the fatigued condition by the paired t-test. Force errors were significantly increased in the fatigued condition compare to non-fatigued condition. This result suggests that the sense of force reproduction can be disturbed by localized muscle fatigue.

The two species of rice bugs causing pecky rice, Cletus punctiger and Cletus schmidti are often observed coexisting in the rice fields of nearby fallow land. Direct feeding damage to rice by C. punctiger and C. schmidti can lead to a reduction in grain quality and quantity. These studies were carried out to investigate the development of C. punctiger and C. schmidti at various constant temperatures ranging from 20 to 30℃, 65% RH, and a photoperiod of 16L:8D. Egg hatchability of C. punctiger/C. schmidti at the temperatures of 20, 25 and 30℃ were 80.6/88.0, 91.7/96.3, 96.4/96.2 %, respectively. The development periods of eggs of C. punctiger/C. schmidti at the temperatures of 20, 25, and 30℃ were 16.4/18.4, 9.4/10.2 and 6.4/7.3 days, respectively. Mean developmental periods of lst, 2nd, 3rd, 4th and 5th nymphs of C. punctiger/C. schmidti at 30℃ were 2.1/2.0, 3.5/4.0, 3.3/5.6, 3.2/4.8 and 5.8/6.9 days, respectively. Oviposition began 8.1 days after emergence at 25℃, and the longevity of female and male were 120.0 and 117.3 days, respectively. Total number of eggs through the life of female were 245.5 laying 2.2 eggs a day in average at 25℃. The development periods of egg and nymphs of C. punctiger were relatively shorter than those of C. schmidti. Availability of male had affected the egg hatchability greatly that laid at 30th day after 60 days period of oviposition in the presence of adult male of C. punctiger. The fertile eggs laid by the female together with male was 92.1% but those without male was only 9.6%.

Possible nematicidal effects of plant extracts of 25 species uninfected by M. hapla were observed at the 5 times dilutions in all treatments and at the 10 times dilutions in Anemarrhena asphodeloides, Acorus calamus, Achyranthes japonica, Agrimonia pilosa, Dianthus chinensis, Geum aleppicum, Houttuynia cordata, Rudbeckia bicolor, Ricinus communis, Scrophularia buergeriana, Sesamum iindicum, Sedum kamtschaticum, and Sanguisorba officinalis. The 13 species plant extracts of 5 times dilutions were evaluated for the suppression effects on reducing densities of M. hapla by treating to C. lanceolata sown and transplanted later in pots. All the plant extracts showed suppressive effects on M. hapla except for A. pilosa. The suppressive effects of A. asphodeloides, A. japonica, A. calamus, D. chinensis, R. communis, and S. buergeriana were over 80%. When the selected plants had been incorporated into the soil before C. lanceolata was sown, the numbers of root galls, egg sacs and J₂ appeared lower in the treatment of 12 plant species than ill control except for S. indicum. But the suppressive effects were lower than the effects of selected plants being cultivated simultaneously in the field. A. calamus and A. japonica exhibited over 70% suppressive effects, among the tested plants.
