본 연구에서 다루고자 하는 이동통신 서비스는 제품과 서비스가 융합된 가장 대표적인 예일 것이다. 따라서 이동통신의 품질은 제품 자체(통신 단말기)의 품질 수준뿐만 아니라 서비스(통신 서비스)의 품질 수준이 모두 고려되어야 할 것이다. 본 연구에서 이 두 가지 품질수준을 모두 고려하여 이동통신의 품질을 측정하였으며, 단일 차원의 충성도가 아닌 인지적, 감정적, 행동적 충성도와 같이 다차원의 충성도 개념을 도입하여 이동통신 제품의 품질과 서비스 품질이 각각의 충성도 형성에 어떤 영향을 미치는지를 실증적으로 고찰해 보았다. 그 결과, 이동통신 서비스의 품질은 인지적 충성도와 감정적 충성도 형성에 직접적 영향을 주었으며, 행동적 충성도에도 간접적 영향이 미치고 있는 반면에 이동통신 제품의 품질, 즉 단말기 품질은 행동적 충성도에 직접적인 영향이 있었다. 추가적으로 충성도 형성의 경로는 단말기와 서비스의 사용기간에 따라 다른 경로를 나타냄을 발견하였다. 본 연구의 결과를 통해 각 이동통신사에 대한 이용자의 충성도는 이동통신 서비스의 품질뿐만 아니라 제품(단말기) 품질에 의하여 크게 영향을 받는 것으로 조사되었다. The recent mobile services are characterized as the convergence of service and product. Thus the quality of the mobile services should be measured by both quality of product(device/phone) and service as well. This study explores the effects of service quality and product quality in building customer loyalty toward mobile services. In addition, this study investigates the interactions among three different kinds of loyalty: cognitive loyalty, affective loyalty, and behavioral loyalty, in building the loyalty. As a result, service quality indirectly affects the behavioral loyalty through the cognitive and the affective loyalty, while product quality directly affects on only the behavioral loyalty. This result shows that the quality of the mobile services is affected by both service quality and product quality. This study also finds that the path of building loyalty has been shown differently in accordance with the usage duration of product and service.

온도조건이 벼멸구(Nilaparvate lugens Stal)의 발육과 산란에 미치는 영향을 정밀하게 조사하여 벼 포장에서의 온도변화에 따른 벼멸구의 발육경과를 예측함으로서 방제적기를 포착하는데 필요한 기초자료를 얻고자 정온과 변온의 식물 생장조정항온기 내에서 벼멸구의 발육속도 및 산란력을 측정하는 실험을 수행한 바 그 결과를 요약하면 다음과 같다. 1. 정온조건에서의 발육 및 산란 벼멸구 난의 부화율은 $25^{\circ}C$에서 가장 높았으며 그 이하나 이상의 온도로 변함에 따라 낮아지는 경향이었다. 난기간은 $27.5^{\circ}C$에서 가장 짧았으며 온도가 낮아짐에 따라 난기간이 길어지는 경향이었고 $30^{\circ}C$ 이상의 고온에서도 난의 발육이 지연되었다. 우화율은 $27.5^{\circ}C$에서 가장 높았고 온도가 낮아짐에 따라 낮아져 $32.5^{\circ}C$와 $35^{\circ}C$에서는 전혀 우화하지 못하였다. 약충기간은 $27.5^{\circ}C$와 $30^{\circ}C$에서 가장 짧았으며 온도가 낮아짐에 따라 길어지는 경향이었다. 우화성충의 수명은 온도가 낮아짐에 따라 길어지는 경향이었고 수컷은 $27.5^{\circ}C$에서 수명이 가장 짧았다. 산란전기는 $32.5^{\circ}C$에서 가장 짧았으며 온도가 낮아짐에 따라 길어져 $17.5^{\circ}C$에서는 $32.5^{\circ}C$에서보다 약 6.5배에 달했다. 산란수는 $25^{\circ}C$에서 가장 많았으며 그 이하나 이상의 온도로 변함에 따라 적어지는 경향이었다. 2. 변온조건과 정온조건에서의 발육 및 산란 같은 유효적산온도에서, 난의 부화율은 정온 조건에서보다 변온조건에서 약 10% 정도 높았으나 난기간은 큰 차이가 없었다. 우화율은 $22^{\circ}C$ 동일 유효적산온도 조건의 경우 변온에서 약 8% 정도 높았으나 $28^{\circ}C$ 동일 유효적산온도의 경우 반대로 정온조건에서 약 8% 정도 높았다. 약충기간은 정온조건에서보다 변온조건에서 약 $4{\sim}6$일 정도 길었다. 같은 유효적산온도에서, 성충의 수명과 산란수는 성충기의 온도가 정온인 것보다 변온인 것에서 길었으며 산란수도 많았다. 한편, 난기에서부터 약충기까지 노출시켰던 온도를 고려해 보면 약충기까지 $28^{\circ}C$ 정온에서 노출시켰던 구에서 각 온도 공히 성충의 수명이 길어져 성충의 수명은 약충기의 온도에 영향을 받았다. 산란전기에는 약충기와 성충기의 온도가 함께 영향을 주었으며 산란수에는 성충기의 온도가 큰 영향을 주었다. 3. 각 발육단계별 발육임계온도 및 유효적산 온도 본 실험결과 계산된 발육임계온도는 난기에서 $14.12^{\circ}C$, 약충기에서 $14.76^{\circ}C$, 성충기에서 $9.12^{\circ}C$, 산란전기에서 $15.95^{\circ}C$로 나타났다. 각 발육단계별 유효적산온도는 난기에서 141.25 온일도(Degree-Day), 약충기에서 167.83 온일도, 성충기에서 349.64 온일도, 그리고 산란전기에서 58.60 온일도 이었다. This study was conducted to know the effects of temperature conditions on the growth and oviposition of the brown planthopper(BPH), Nilaparvata lugens $St{\aa}l$. Results obtained were to predict the timing of the BPH control by measuring population dynamics of the BPH in response to temperature fluctuations upon migration of the insects in paddy fields. Developmental and ovipositional rates under constant and alternating temperature conditions were observed in a plant growth cabinet. Hatchabilities of eggs of the BPH were the highest at $25^{\circ}C$ and were decreased below or above the optimum temperature. Egg periods were the shortest at $27.5^{\circ}C$ and prolonged with decreasing temperature, but retarded at higher temperature above $30^{\circ}C$. Adult emergence rates were the highest at $27.5^{\circ}C$ and reduced with decreasing temperature, and no adult emerged at $32.5^{\circ}C$ and $35^{\circ}C$. Developmental period of nymph was the shortest at both $27.5^{\circ}C$ and $30^{\circ}C$, but extended with decreasing temperature. Female longevity was increased with decreasing temperature and the male longevity was the shortest at $27.5^{\circ}C$. Preoviposition period was the shortest at $32.5^{\circ}C$, but prolonged with decreasing temperature. It was about 6.5 times longer at $17.5^{\circ}C$ than that at $32.5^{\circ}C$. Number of eggs oviposited per female was the greatest at $25^{\circ}C$, but decreased at the temperature below or above the optimum. Under the same total effective day-degrees, hatchabilty at the alternating temperature was about 10% higher than that at the constant temperature but egg period at the alternating temperature was nearly identical as that at the constant. Under the $22^{\circ}C$ condition, emergence rate was about 8% higher at the alternating temperature than that at the constant, however, at the $28^{\circ}C$, the rate was about 8% higher at the constant than that at the alternating. Nymphal period was about $4{\sim}6$ days longer at the alternating temperature than that at the constant. Under the same total effective day-degrees in adult stage, both longevity and oviposition period were longer at alternating temperature than those at the constant. Number of eggs oviposited per female was also higher at the alternating. Longevities of females reared under $28^{\circ}C$ of constant temperature was the longest no matter what temperatures they were exposed after the emergence. This result seems to be indicating that female longevity is greatly influenced by the temperature to which they were exposed durings immature stages. Preoviposition period was affected by the temperature exposed during the nympal and adult stage whereas the number of eggs oviposited was affected by the temperature during the adult stage only. Based on the results from this study, the developmental threshold temperatures seem to be $14.12^{\circ}C$ for eggs, $14.76^{\circ}C$ for nymphs, $9.62^{\circ}C$ for adults, and $15.95^{\circ}C$ for preoviposition period. Estimated values of the total effective temperature for completing each stage were 141.25 day-degrees for eggs, 167.83 day-degrees for nymphs, 349.64 day-degrees for adults, and 58.60 day-degrees for preoviposition.

배순도,김현주,박정규,이건휘,박성태,송유한,Bae, Soon-Do,Kim, Hyun-Ju,Park, Chung-Gyoo,Lee, Geon-Hwi,Park, Sung-Tae,Song, Yoo-Han 한국응용곤충학회 2005 한국응용곤충학회지 Vol.44 No.4

규격이 다른 5가지 사육용기, A용기 (원통형, 직경 10 cm, 높이 4 cm), B용기 (원통형, 지름 14.5 cm, 높이 2.8 cm), C용기 (사각통, 가로${\times}$세로 : $6.5{\times}6.5cm$, 높이 10 cm), D용기 (원통형, 밑지름 9 cm, 밑지름 11.5 cm,높이 10.8 cm), E용기 (원통형, 직경 15 cm, 높이 7.5 cm)에 두류종자 (대두+땅 콩종자) 및 스폰지급수물을 제공하여 $24^{\circ}C$, 16L:8D 실내조건에서 가로줄노린재의 부화율, 우화율 및 산란수를 조사하여 증식율을 구하였다. 난기간은 사육용기에 관계없이 6일 이었다. 부화율은 $63{\sim}80%$로 B용기에서 가장 높았다. 영기별 발육기간은 1령에서 5일, 5령에서 11일로 영기가 증가할수록 현저히 증가하였다. 약충기간은 $35{\sim}36$일로 사육용기에 따른 현저한 차이는 없었다. 우화을은 $65{\sim}82%$로 B용기에서 가장 높았으며, 다음은 A용기 였다. 성충수명은 수컷에서 $35{\sim}83$일, 암컷에서 $32{\sim}79$일 이었고, 성별에 관계없이 B용기에서 가장 길었다. 암컷의 산란수는 $38{\sim}86$개로 사육용기에 따라 현저한 차이가 있었으며, B용기에서 가장 많았고, E용기에서 가장 적었다. 따라서 가로줄노린재의 1세대 증식율은 약 $17{\sim}56$배로 사육용기에 따른 현저한 차이와 함께 B용기에서 가장 높았다. 그러므로 실내에서 가로줄노린재를 가장 안정적으로 사육하기 위해선 B용기를 이용하는 것이 가장 효과적인 것으로 나타났다. The embryonic and postembryonic developments of Pierodorus hybneri Linnaeus were observed in 5 different rearing cages such as A (Cylindrical, 10 cm in diameter, height of 4 cm), B (Cylindrical, 14.5 cm in diameter, height of 2.8 cm), C (Rectangle, 6.5 by 6.5 cm in $length{\times}breadth$, height of 10 cm), D (Cylindrical, 9 cm in bottom diameter, 11.5 cm in upper diameter, height of 10.8 cm) and E (Cylindrical, 15 cm in diameter, height of 7.5 cm) containing soybean and peanut seeds as feeding food, and sponge-water container under laboratory condition of $24^{\circ}C$ and 16L:8D. Egg duration was 6 days regardless of rearing cages. Hatchability ranged from 63 to 80% with the highest in B (14.5 cm in diameter, 2.8 cm in height) rearing cage. Instar duration was longer from 5 days in 1st instar to about 11 days in 5th instar. Nymphal duration showed 35 to 36 days with'3ut significant difference in rearing cages. Percent emergence was in range from 65 to 82% with the highest in B rearing cage. Adult longevity was 35 to 83 days for male, and 32 to 79 days for female, and was the longest in B rearing cage. Total number of eggs laid by female adult was in range from 38 to 86 with significant difference in rearing cages, and was the most in B rearing cage. Accordingly, the reproductive rate of P. hybneri for 1 generation was within 17 to 56 times, and was the highest in B rearing cage. Therefore, it could be concluded that B cage is most suitable for stable rearing of P. hybneri under laboratory condition.

최근 들어 우리나라에서 토마토 소비가 급증하고 있으며 많은 토마토 품종이 시장에서 거래되고 있다. 그러나 토마토 품종육성에 이용되는 부모 계통의 유전적 다양성이 낮아 형태적인 특성에 의한 토마토 품종의 구분은 매우 어려운 현실이다. 이에 따라 토마토의 품종을 구별해 낼 수 있는 분자표지의 개발이 필요한 실정이다. 본 연구에서는 SNP를 탐색하고 토마토 품종 구분을 위한 SNP 마커를 개발하였다. SNP분자표지는 고추 유전체 서열로부터 파생된 COS Ⅱ 분자표지와 인트론 기반 분자표지를 기반으로 선발되었으며, HRM분석을 통해 다형성을 테스트 하였다. 전체 628개의 프라이머 조합 가운데 PCR을 통해 크기가 500bp 이하의 단일 밴드가 증폭된 417개의 프라이머 조합을 선발하였다. 417개의 프라이머 조합을 이용해 4개의 토마토 계통을 대상으로 HRM 분석을 실시하였으며, 다형성을 보인 70개의 프라이머 조합을 선발하였다. 70개의 프라이머 조합을 이용하여 32개의 토마토 품종을 대상으로 HRM 분석을 실시하였다. HRM분석을 통해 총 11개의 SNP 분자표지가 선발되었으며, 이 분자표지를 이용해 시판중인 32개의 토마토 품종을 모두 구분할 수 있었다. The consumption of tomato has greatly increased recently in Korea, and a large number of tomato cultivars are commercially available in the market. However, identification of tomato cultivars by morphological traits is extremely difficult because of the narrow genetic diversity of breeding lines. Therefore, it is necessary to develop molecular markers for cultivar identification in tomato. In this study, we surveyed single nucleotide polymorphism (SNP), and developed SNP marker sets for tomato cultivar identification. SNP markers were developed based on conserved ortholog set II (COSII) and intron-based markers derived from pepper EST sequences, and marker polymorphism was tested using high-resolution melting (HRM) analysis. A total of 628 primer sets was tested, and 417 primer sets amplifying single bands were selected. Of the 417 primer sets, 70 primer sets showing HRM polymorphism among 4 inbred lines were selected. Eleven markers were selected from the 70 primer sets and subjected to cultivar identification analysis. Thirty two commercial tomato cultivars were successfully identified using the marker set.

We report septicemic colibacillosis accompanied by white-spotted kidney in a 30-day old female Holstein-Friesian dairy calf. Grossly, there were numerous white spots sized average 0.5cm in diameter in both kidneys. When sectioned sagittally, there were radially oriented gray streaks extending outward and reaching the renal cortex. The renal papillae were ulcerated, white to gray in color and very friable. Histologically, there was extensive purulent inflammation characterized by severe neutrophilic cellular infiltrations in the tubular lumens and interstitia. In addition, massive coagulative necrosis were found in the apices of papillae. Numerous Gram-negative bacterial colonies were detected in both of the renal and lung tissues. Beta-hemolytic Escherichia coli (E. coli) was purely isolated from the renal parenchyma, peritoneal surface and pleural surface. Based on the above results, we suggest that the generalized septicemia with pyelonephritis may be oriented from the lower urinary tract infection with E. coli in this case.

This study was conducted in the process that the basic plan of the formation of the thermal energy complex in the Iwon reclaimed land of Taean was being made. Targeting for the large-sized greenhouse to be made in this area, it examined the cooling and heating load and the amount of ventilation, and also analyzed the economic efficiency of heating. The research results are as per the below: The minimum ambient temperature of this area was measured on January 7, 2001, which was $-18.7^{\circ}C$, and the maximum ambient temperature of this area was measured on July 24, 1994, which was $36.7^{\circ}C$. The maximum heating load was 39,011 MJ/h, but the date when the maximum heating load was not consistent with the date when the minimum temperature was measured. The maximum cooling load was 88,562MJ/h, It was approximately 2.3 times of the maximum heating load, which was measured at 14:00 hours on September 4, 2000. The maximum amount of ventilation heat was 138,639MJ/h. Assuming the rate of solar heat use as 10%, 20%, 50%, and 100%, the total sum of cost-benefit would be ￦-193,450,000, ￦-634,930,000, ￦-3,372,960,000, and ￦-9,850,420,000, respectively 20 years later. The break-even point of the geothermal heat pump would be about 4 years for 10% use, about 3 years for 20% or 50% use, and approximately 6 years for 100% use. It was found that 50% use would be most advantageous. In case two systems are combined, the break-even point will be 10 years, 8 years, and 11 years respectively.

Toxocara (T.) canis, round worm of dogs and cats, is probably the most common gastrointestinal helminthes of domestic canid and is ascarid nematodes in the order Ascaridida, family Toxocaridae. The prevalence of patent toxocariasis is highest in the young dogs and much less common in adult dogs. There are few reports on the status of T. canis prevalence of dogs in Korea. Few cases of human visceral larva migrans also reported in Korea. However, as far as we know, there is no report on the canine toxocariasis case determined by pathological findings in Korea until now. In this research, we diagnosed canine toxocariasis by fecal egg test and pathologic findings in 2-month old two Pointer dogs. Typical T. canis eggs were detected in the fecal test. Numerous adult ascarids in the lumen of small intestine and stomach in one dog and multifocal white necrotic lesions in lung, liver, and kidney in another dog were observed grossly. Histologically, multifocal necrosis, eosinophilic inflammation and intralesional ascarid larva were prominent findings in the lung, liver and kidney.
