        Stathmooda masinissa is one of the most serious lepidopteran pests which damaging the furit of persimmon. Its pheromone composition has been idetified as (E4,Z6)-4,6-hexadecadienyl acetate (E4,Z6-16Ac) and (E4,Z6)-4,6-hexadecadien-1-ol (E4,Z6-16OH). We evaluated electrophysiological response of (E4,Z6)-4,6-hexadecadienal (E4,Z6-16Ald) and attractivenss of E4,Z6-16Ald by combination of two pheromone components. E4,Z6-16Ald evolked electrophysiological responses as same to that of two pheromones. The lure combined with E4,Z6-16Ald and two pheromone components attracted more male S. masiissa.

        Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes and its female produces sex pheromone with two isomeric components, 2Z-homofarnesal and 2E-homofarnesal. Two day old virgin adults were exposed to 0, 200, 300, 400, 500 & 600 Gy gamma radiation and effect on longevity, fecundity, sterility and pheromone production were studied. Longevity (female; P < 0.001, male; P < 0.001) and fecundity (P < 0.001) were dose-dependently affected by the gamma irradiation. Both adults were totally sterilized by the tested doses of gamma irradiation as depicted by the null hatchability of laid eggs. Gas chromatography-mass spectrometry for solid phase micro extraction revealed that both of the pheromone components were significantly but not completely reduced by 300 Gy. It is a pre-requisite for a successful sterile insect technology that the sterility of ABB is induced without the total disruption of calling behavior.

        Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes. It is ideal to estimate its field population before it invades the stored legume stuffs. The seasonal occurrence was monitored with rocket traps supplied with synthetic female sex pheromone and with sweep netting during 2015-2016. Harvest damage was evaluated by taking purposive samples of the pods at harvest. Over-wintering stage was identified from the pod samples of left over plants. The results ascertained that October was the peak season of ABB in the azuki bean field. Grain damage and weight loss of the harvested azuki bean were 2.7% and 2.4% respectively, which could be the inoculum for storage loss. The adult emergence only from live pupae collected from pods revealed for its most probable over-wintering stage. In all, this study provides insight into some field ecological parameters of ABB that could be helpful in adopting its management strategies.

        Plant essential oils (EOs) exhibit an array of biological activities against insect pests. However, their negative influences on the pheromonal activity of azuki bean beetle (ABB), Callosobruchus chinensis L., the field-to-storage pest of legumes, have not received research attentions. We evaluated the effects of three EOs and their two major components on the attractiveness of male ABBS to synthetic homofarnesal (2E- : 2Z-homofarnesal = 6:4) using Y-tube olfactometry in laboratory and rocket traps in the semi-open vinyl house. The tested EOs of Illicium verum, Croton anisatum and Gaultheria fragrantissima as well as the major components, trans-anethole and methyl salicylate ascertained significant negative effect against homofarnesal both in Y-tube olfactometry and in semi-open vinyl house tracing out a new opportunity of integrating them in ABB management programs both in field and storage.

        The purpose of this study was to identify the effect of chiropractic treatment on the alignment of the lower extremities and plantar pressure in subjects with pelvic misalignment. The study included 20 subjects with pelvic misalignment. They were divided into two groups: the chiropractic treatment group (n=10) and stretching group (n=10). They performed the intervention for 10 minutes, twice a week, for weeks, and pelvic displacement, functional leg length, and plantar pressure were measured In chiropractic group, both pelvic displacement and plantar pressure distribution were significantly decreased and leg length difference was significantly increased (p<.05). However, in the stretching group, only pelvic displacement was significantly reduced (p<.05), and leg length difference and plantar pressure distribution decreased slightly. There was no significant difference in all variables between the groups. This study suggests that chiropractic and stretching are effective in changing pelvic displacement, leg length difference, and plantar pressure distribution.

        The aim of the study was to investigate the effects of incentive spirometry and Ujjayi breathing technique on the pulmonary function of smokers. Subjects were individuals who had a smoking habit of at least a year. Subjects were randomly divided into 3 groups: the incentive spirometry group (n=8), Ujjayi breathing technique (n=9), and a group applying both incentive spirometry as well as Ujjayi breathing technique (n=8). Each intervention was performed twice a day, 5 times a week, for a total of 8 weeks whereupon the change in pulmonary function was evaluated. A spirometer was used to measure FVC, FEV1, and FEV1/FVC. The survey used for this study included the Fagerström Test of Nicotine Dependence (FTND) and the Shortness of Breath Questionnaire (SOBQ). Study results for the comparison within groups showed that in the group that performed both the incentive spirometry and Ujjayi breathing technique, FEV1 improved with statistical significance (p<.05). Furthermore, within this comparison the FEV1/FVC improved with statistical significance. Comparison amongst the groups showed no statistically significant differences in all areas. Following, to effectively increase pulmonary function in young adult smokers, both incentive spirometry and Ujjayi breathing technique should be employed together.

        The purpose of this study was to measure the mean peak mobilization forces to the cervical spine 3-5 with grade III and grade IV of posteroanterior (PA) mobilization. Asymptomatic 25 college subjects were participated in the trial and eligible physical therapists performed cervical mobilization. The mean peak mobilization force was measured during the PA mobilization with grade III and grade IV by attaching a flexible force transducer over the C3-C5 spinous process. Three cycles of PA mobilization were performed in each spine and the therapist took approximately 2.5s to complete mobilization. After applying the grade III mobilization to the C3-C5, 30 minutes later, the grade IV mobilization was applied to the same area again. There were no significant differences between C3, C4 and C5 during grade III as well as grade IV. Upon comparing the mean peak force of grade III with mean peak force of grade IV at the C3, C4 and C5 respectively, an insignificant difference was also observed. The mean peak mobilization force was 4.53±1.79 N at the C3, 5.10±1.91 N at the C4, and 5.17±2.63 N at the C5 during grade III force was applied. The mean peak mobilization force was 4.40±1.56 N at the C3, 5.53±2.01 N at the C4, and 5.38± 2.73 N at the C5 during grade IV force was applied. This study suggested that the mean peak force of the grade III and grade IV mobilization in the C3-C5 was similar each other, also there was no difference between mean peak force of grade III and grade IV on C3, C4 and C5.

        The entomopathogenic fungus Metarhizium anisopliae B is a powerful biological control agent against Monochamusalternatus, a crucial mediator of the pinewood nematode Bursaphelenchus xylophilus. In this study, production of destruxins(dtxs), insecticidal cyclic hexadepsipeptides, was monitored in the submerged culture of M. anisopliae B. Three typesof dtxs, i.e., destruxin A, B, and E, were produced during the culture. Among the three dtxs, the production yield ofdestruxin A was best, followed by destruxin B and E. Destruxin A production was increased when pH was controlledat 6.0, whereas production of destruxin E was not affected by the pH control. The highest yield of dtxs A, B, and Ewere 16.4, 7.3, and 6.1 mg L-1, respectively. Considering that process for dtxs production has not been optimized, M.anisopliae B has more powerful implication as a biocontrol agent.

        The entomopathogenic fungus Metarhizium anisopliae is one of potent biological control agents against a variety ofinsect pests. In this study, we investigated enzyme production of M. anisopliae strains A and B. They produced extracellularenzymes for degrading the epidermis of Monochamus alternatus, a crucial mediator of the pinewood nematode Bursaphelenchusxylophilus. With Q-TOF MS/MS analysis, 29 kDa protein, a major band on a SDS-PAGE gel, was identified as subtilisin-likeserine protease PR1A. M. anisopliae A produced an extracellular enzyme more efficiently than M. anisopliae B: however,enzyme activities targeted for the cuticle were comparable. Our results suggest that the two strains of M. anisopliae havethe biological potential against M. alternatus with insecticidal protease production.

        An increased use of organic phosphorous based chemical pesticides in domestic and overseas agriculture has resultedin emergence of tolerant strains of insect pests. These pests have spread throughout South Korea and are responsible forsignificant reduction in crop yields. Furthermore, as yet there is no effective way of controlling these insects or the damageresulting from pest infestation. To this end, we are attempting to develop biological control based methods to protectcrop plants against insect pests. A screen for biocontrol agents conducted in five farms that were heavily infested bynematodes in 2015-2016 identified Aspergillus niger F22 strain that was very effective against root-knot nematode. Afour-time treatment with A. niger F22 at an internal of ten days was able to reduce nematode population by 70-90%compared to untreated controls. The biocontrol agent was also more effective compared to ograno-phosphorus based pesticide,which caused a 30% reduction in nematode population. Notably, the extract (suspension concentrate) prepared from A.niger culture was equally effective in controlling the root-knot nematode and is currently being developed as a marketableproduct under the brand name “NAMAFREE”.

        This study was carried out to investigate the management characteristics and techniques by comparing and analyzing the process of mixing, sterilization, cooling, inoculation and incubation for bag cultivation of L. edodes. The medium was sterilized after mixing it for 30 minutes, 1 and 2 hours respectively. The general moisture content of the sawdust substrate has been adjusted to 65%, while the case of the L. edodes substrate was 55%. Only 5% of wood chips of 5-8 mm in particle size were mixed to secure the space of the sawdust particles. As a result, mycelial growth was 1.4cm faster and the density was better(+++) than control(++). Wood chips are soaked in advance for a week during winter and 4 days during summer. There is an average number of 1.6x108 (cfu) of microorganisms in the sawdust that has been piled for six months outdoor. In summer, it has to be used immediately after mixing sawdust. High-pressure sterilization should be performed to use as a mushroom spawn, and to improve physical properties, it was great to sterilize the medium at a normal-pressure. There are height and width type for bags to be consumed for bagging. When the height was reduced into 17cm and the width was increased into 13cm, the browning period was shortened by 30 days and the period of mycelial growth was shortened by 25 days. The sterilized medium had an average of 4x103(cfu) of microorganisms at 25°C and 1.3×102 (cfu) at 15°C. After 25 days from inoculation in vitro, the growth condition of sawdust was the best with 13.2 cm, followed by grain spawn and liquid respectively. When inoculated with liquid spawn, the moisture content of substrate should be adjusted to 55% to 50% in advance.

        This study aims to identify the effects of extracorporeal shock wave therapy and stretching technique on flexibility, muscle tone and pressure pain threshold of a shortened hamstring. A total of 40 patients with hamstring shortening was randomly assigned to either the extracorporeal shock wave therapy group (n=20) or extracorporeal shock wave therapy with stretching technique group (n=20) to identify the effects of the two different forms of physical therapy intervention. All the participants underwent extracorporeal shockwave therapy twice a week for 3 weeks, and the extracorporeal shockwave therapy with stretching technique group performed stretching techniques with the same frequency for 3 weeks. To measure hamstring flexibility before and after intervention, the passive straight leg raising test was performed, and muscle tone and pressure pain threshold were assessed. The flexibility of the hamstrings significantly improved, while the pressure pain threshold increased in both groups. These findings suggest that the effective in improving hamstring flexibility, reducing muscle tone, and increasing pressure pain threshold in adults with hamstring shortening.

        The aim of the present study was to compare the effects of Rolfing and Swedish massage. In total, 105 patients with cervical myofascial pain syndrome were divided into two groups based on the intervention: a 40-min Rolfing session (n = 52) or a 40-min Swedish massage session (n = 53). Pre- and pos-tintervention visual analog scale (VAS) scores for pain, muscle tone (Myoton F), muscle elasticity (Myoton D), and muscle stiffness (Myoton S) were measured to compare treatment effects between the two groups. The results revealed a significant decrease in the VAS score for pain, Myoton F, and Myoton S (p < .05), with no change in Myoton D (p > .05), after the intervention in the Rolfing group. Similar findings were obtained for the Swedish massage group. Intergroup comparison of the degree of improvement after the intervention revealed no significant difference for any variable. The findings suggest that both group indicated a similar decrease in pain, muscle tension, and muscle stiffness after the intervention, with no significant improvement in muscle elasticity.

        Type1 diabetes mellitus (DM) is generally known to be caused by destruction of insulin-producing pancreatic β cells or an immune-related problem. Polydipsia is a representative symptom of DM, and it has been reported that this condition is closely related to xerostomia and is considered that hyposalivation from the salivary gland results in this phenomenon. Although various studies have reported that induction of diabetes reduces endogenous stem cells in other organs (heart, brain etc.), diabetes-related changes in endogenous stem cells in the salivary gland have not yet been well established. Therefore, in this study, to verify the change in salivary gland stem cells after diabetes, salivary gland tissues in the control and diabetes-induced groups were processed by histochemistry (Masson’s trichrome staining) for morphological analysis, TUNEL assay for cell death, and immunohistochemistry (Ki-67 and c-Kit) for cell proliferation and maturation. Diabetes induced by STZ leads to vacuolization, apoptosis, and reduction in proliferating cells/salivary gland stem cells in salivary glands of rats. This result suggests that diabetes may be associated with reduction in salivary gland function such as degeneration and inhibition of regeneration in the salivary gland.

        The concept of „Sustainability‟ has become as major concern and it used by consumers and corporations to convey the concept of taking care of the environment. Environmental concern has led to sustainable consumption in a variety of product categories, such as electricity, textiles, apparel, food, and grocery products (Chan, 2001; Harrison, Newholm, & Shaw, 2005; Vermeir & Verbeke, 2006a, 2006b). Interest of the negative environmental impacts are rapidly increasing in present fashion business and consumer behavior has become a rising concern of the consumption and fashion supply chain to apply sustainable consumption (Birtwistle & Moore, 2007; Fineman, 2001). The environmental and social concern recognized in fashion industry from 1990‟s. However, the complexity of conceptual definition of sustainability and ecologically responsible consumer generates different and mistaken perception to consumer. In addition, in fashion industry, the terms of „eco-fashion‟, „environmentally friendly fashion‟,„green fashion‟, „ethical fashion‟, and „sustainable fashion‟ are frequently used interchangeably to describe the same concept. These interchangeable terminology is leading to confusion of the readers by the non-unified terminology (Choi et al., 2012). Also, consumers seem to have narrow scope and little understanding of sustainable fashion. In general, consumers focuses on environmental aspect not the wide-range of complexity of environment, social, and economical concern (Cervellon, Hjerth, Ricard, & Carey, 2010). The growing number of fashion brands are leveraging on green branding initiatives. Green marketing is increasing rapidly in corporate aspects and for a consumer perspective, global consumers are recognizing a personal accountability to take responsibility for social and environmental issues. Despite the fact many of individuals‟ willingness to purchase green products has increased in the last few years, however, there is limited studies suggest that purchase of green or sustainable products. Consumer research on sustainable fashion has mainly focused on consumer behaviors towards sustainable fashion products (SFPs); however, relevant studies that examined the whole process of the predicting proenvironmental behavior cross nationally value and the eWOM are still scarce. The purposes of research model are 1) to identify the determinants of eWOM intention on consumers' purchase intentions, 2) to examine the information adoption process as precursors of purchase intention of sustainable fashion, and 3) to testify different message types effects to information adoption process.

        This study focuses on exploring how to close attitude-behavior gap of consumers with regards to both recycled and upcycled fashion products. Specifically, this study is to explain the purchase gap between purchase intention and purchase experience of these sustainable products. Although many consumers had positive attitudes toward sustainable products, they often ended up not purchasing them. Factors including perceived values, risks, environmental concern, perceived consumer effectiveness, subjective norms, and demographic variables were examined to understand the discrepancy. The results indicate that antecedents of purchase intention were different from those of purchase experience and that influencing factors for recycled products were different from those for upcycled products. This study provides insights into understanding consumers and developing effective strategies to encourage desirable behaviors.

        With the increasing popularity of social media, opinion leaders who have lots of followers have recently created strong advertising effects and generated greater sales. The emergence of online stars, Wang Hong in China, comes at a time when self-media gains popularity and e-commerce requires innovative ways to endorse brands in fashion industry. This study examines how these influencers impact consumers’ attitude toward the products they use and recommend. Specifically, this study investigates whether and how source attributes, social media content characteristics and judgment of product fit affect attitude of Chinese fashion consumers. As the perceived fit between the endorser and the product positively affect source credibility (Kamins, 1990) as well as consumer attitude toward the advertised product (Till & Busler, 2000), the present study hypothesized that the fit between the online star and the product will increase the perceived endorser credibility and product attitude of consumers. The effect of the fit between the product and the self-media content on the attitude toward the content or the product was also examined. Implications for managing marketing strategies as well as future research directions are subsequently discussed.
