The genus Ypsolopha Latreille is the largest taxa in Ypsolophidae, comprising over 140 species worldwide. More than 100 species have been described from the Palaearctic and Oriental Regions. In Korea, 10 species have been listed by Byun et al. (2009), and recently 3 new recorded species were reported by Sohn (2010). Ypsolopha species have been known feeding on conifers and dicotyledonous plants. But studying of host plants is still not discovered thoroughly. In the present study, I carried out to breed larvae ofYpsolophid moth based on Japanese study in a laboratory. And reported one newly recorded species from Korea. Also, we provide description of adult, pictures of adults genitalia and a checklist of host plants is also provided.

Purpose: Yoga center is a service industry that sell intangible goods. And service quality depends on who, when, where and how and it can be evaluated differently depending on characteristics of users. At this point, yoga centers that experienced operational difficulties, it can``t be understand the needs of diversified users with increasing of yoga centers. It is a task of great significance to analyze selection attributes of yoga center users with IPA (importance-performance) to develop the yoga industry and secure competitive advantage with other industry. Therefore, the purpose of this study was to analyze selection attributes of yoga center users with IPA method and provide efficient management strategy for the operator of yoga center in the operation``s difficulties according to excessive competition. Method: This researcher distributed 250 importance-satisfaction questionnaire sheets about the yoga center in busan metropolitan city. And 233 questionnaires were finally used for this study excluding 17 considered to have insincere answers or low reliability out of 250 questionnaires in total and then treated the data as below using SPSS 21.0. For collected data, the statistically significant level was all set up as α=.05. First, the study conducted frequency analysis to know characteristics of the subjects. Second, it conducted exploratory factor analysis and reliability analysis to know reliability and validity of each item of the questionnaires. Third, it conducted paired sample t-test for the difference verification of IPA. Result: The main results of the study were as follows. First, there was partially significant differences between importance and performance regarding the sub-categories of program, leader, facility and convenience. Second, as the results regarding IPA, quadrant Ⅰ indicating ``Keep up the Good Work`` included program interesting, leader expertise, leader words and actions, leader career and leader features, etc. Third, quadrant Ⅱ indicating ``Concentrate Here`` included program composition, cleanliness state and lesson fee. Fourth, quadrant Ⅲ indicating ``Low Priority`` included program diversity, class space and interior, presence of incidental facilities and discount benefit, etc. Lastly, quadrant Ⅳ indicating ``Possible Overkill`` included time of the program, lighting state and transport convenience. Conclusion: First, there was partially significant differences between importance-performance on all items. Second, in the priority order of importance, program composition indicated high order but in the priority order of satisfaction, leader expertise was indicated high. Third, program composition, cleanliness state and lesson fee were included to quadrant Ⅱ. If improving search for the insufficient part by analyzing and understanding about these properties, it can be increase customer satisfaction and lead to increase the membership of the yoga center.

The advent of the Internet of Things (IoT) technology, which brings many benefits to our lives, has resulted in numerous IoT devices in many parts of our living environment. However, to adapt to the rapid changes in the IoT market, numerous IoT devices were widely deployed without implementing security by design at the time of development. As a result, malicious attackers have targeted IoT devices, and IoT devices lacking security features have been compromised by attackers, resulting in many security incidents. In particular, an attacker can take control of an IoT device, such as Mirai Botnet, that has insufficient security features. The IoT device can be used to paralyze numerous websites by performing a DDoS attack against a DNS service provider. Therefore, this study proposes a scheme to minimize security vulnerabilities and threats in IoT devices to improve the security of the IoT service environment.

Trimethylamine (TMA) is a well-known off-odor compound in fish and fishery products and is a metabolic product of trimethylamine N-oxide (TMAO) generated by the enzymatic action of microorganisms. The off-odor is a factor that can debase the value of fish and fishery products. The present study aimed to remove TMA using lactic acid bacteria (LAB). A total of fifteen isolates exhibiting the TMA reduction efficacy were isolated from Korean traditional fermented foods. Among these isolates, five LAB isolates (Lactobacillus plantarum SKD 1 and 4; Lactobacillus paraplantarum SKD 15; Pediococcus stilesii SKD 11; P. pentosaceus SKD 14) were selected based on their high TMA reduction efficacy. In situ reduction of TMA efficacy by the LAB cell-free supernatant was evaluated using a spoiled fish sample. The results showed effective TMA reduction by our selected strains: SKD1 (45%), SKD4 (62%), SKD11 (60%), SKD14 (59%), and SKD15 (52%), respectively. This is the first study on TMA reduction by the metabolic activity of LAB and in situ reduction of TMA using cell-free supernatant of LAB. The present finding suggests an economically useful and ecofriendly approach to the reduction of TMA.
