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.

The recent developments of artificial intelligence (AI), such as Google AlphaGo and IBM’s Watson, defeating human experts in public game venues, have instigated much surprise and awe among us. We are now genuinely curious about the true growth potential of AI into the future. Some of us are already imagining a darkening future where all human managerial positions can be replaced by machines leaving humans in a marginalized place after the point of singularity where machine intelligence achieves intellectual superiority over us and becomes a truly autonomous being. Likewise, the potential of AI has been overestimated or underestimated; rarely has it been addressed in the open context where marketing academics serve the role of an architect of future marketing AI, to provide valuable insights. We are enlightened about a possibility that the future of and marketing can greatly benefit from advanced forms of artificial intelligence. But how and where can this new technology be integrated in the every-day lives of consumers, to optimize business functions and create much higher levels of collective value for consumers, companies, and machines altogether? In this talk, we will discuss the following three points related to the AI and its potential future in the field of marketing. First, for consumers, we will discuss how marketing AI can help consumers to make better decisions about their eating, health, and consumption to enjoy better life, do more, and be happy. Second, for business, we will discuss the roles of AI and design a collaborative work process that can employ both human ingenuity and machine accuracy. Third, we suggest ethical issues related to marketing AI, delineating its boundaries and suggest governing policies to prevent potential danger spots. The purpose of talk is not to present a definitive answer, but to instigate an open discussion among the marketing academics, about the future of marketing, where AI will be an indispensable partner in the value creation process.

The purpose of this study is to provide fundamental clinical data for the treatment plan and rehabilitation of patients with cervical hypolordosis by comparing the cervical headache and muscle activity after cervical stretching exercise and cervical traction, which are generally applied to patients with cervical hypolordosis. The research subjects included 20 patients without gender division who were diagnosed with cervical hypolordosis. After applying cervical stretching exercise and cervical traction for six weeks, cervical headache and the activity of the muscles around the cervical vertebra(upper trapezius muscle, sternocleidomastoid muscle, splenius capitis muscle, and anterior temporal muscle) were investigated and the following results were obtained. In a comparison of the within group intervention effects of the two groups, cervical pain statistically significantly decreased in the cervical stretching exercise group. According to the results of analyzing the change of muscle tension in the upper trapezius muscle, both the cervical traction group and showed a statistically significant within group difference in the left and right side. According to the results of analyzing the change in the muscle tension of the splenius capitis muscle, both groups showed a statistically significant within group difference in the left and right side. In a betweengroup comparison, a statistically significant difference in the right side was observed. These results confirm that cervical vertebra traction and cervical stretching exercise decrease the cervical headache and muscle activity of the upper trapezius muscle and the splenius capitis muscle among patients with cervical hypolordosis.

The goal of this research was to develop a portable system that could be used to evaluate the quality of milk in real time at a raw milk production site. A real-time portable quality evaluation system for raw milk was developed to enable non-destructive quality evaluation of somatic cell count (SCC), fat, protein, lactose, and total solid (TS) in milk samples. A prediction model of SCC, fat, protein, lactose, and TS was constructed using partial least squares (PLS) and 200 milk samples were used to evaluate the prediction performance of the portable quality evaluation system and high performance spectroscopy. Through prediction model development and verification, it was found that the accuracy of high performance spectroscopy was 90% for SSC, 96% for fat, 96% for protein, 91% for lactose, and 97% for TS. In comparison, the accuracy of the portable quality evaluation system was relatively low, at 90% for SSC, 95% for fat, 92% for protein, 89% for lactose, 92% for TS. However, the measurement time for high performance spectroscopy was 10 minutes for 1 sample, while for the portable quality evaluation system it was 6 minutes. This means that the high performance spectroscopy system can measure 48 samples per day (8 hours), while the portable quality evaluation system can measure 80 (8 hours). Therefore, it was found that the portable qual ity evaluation system enables quick on-site quality evaluation of milk samples.

We compare American and Korean reactions to the persuasiveness of environmental advertising campaigns. Findings indicate that the effectiveness of the message assertiveness varies depending on recipients’ cultural backgrounds. Study 1 demonstrates that among Americans an assertive recycling message that contains imperatives such as should, must and ought is less effective than a non-assertive message that contains terms such as could, might and worth, yet among Koreans such reactance-driven boomerang effect is not observed. Study 2 extends the findings by conceptually replicating this finding in a different context—energy saving campaign—and further shows that perceived threat to freedom mediates the effects

The purpose of this study is to observe how balance exercise on an unstable platform and on a stable platform affects balance ability. The subjects were 35 adults in their 20s and were randomly assigned to a stable platform group and an unstable platform group. They performed balance exercise three times per week for six weeks. Balance exercise introduced by previous research was modified and complemented for use in this study. Balance ability of the subjects was measured through center of pressure(COP) area, medial-lateral displacement, and anterior-posterior displacement using a portable balance platform BT4. There was significant difference in the COP area between the unstable platform exercise group and the stable platform exercise group. In comparison in differences between the unstable platform exercise group and the stable platform exercise group after the exercise, there was significant difference in anteriorposterior movement. Therefore, exercise on an unstable platform is more effective than exercise on a stable platform in strengthening balance ability.

This study was conducted to investigate the effect of biological membrane transfer modifier, lysophospholipd (LPLs) on the parameters from in vitro rumen simulated fermentation. Commercially available LPLs product (LipidolTM) was supplemented into experimental diets which consisted of orchard grass and concentrate diet (60:40) in different levels (0.1%, 0.3% and 0.5%). Then in vitro rumen simulated fermentation was performed. Although, a declining trend of pH was found in treatments, all pH values were detected in a range relevant to normal rumen fermentation. Gas production, ammonia nitrogen and total VFA production were greatly influenced by the supplementation of LPLs. All parameters were increased along with increased levels of LPLs in diet. As a result, 0.1% of LipidolTM is recommended based on the determined in vitro rumen fermentative parameters in this study.

The purpose of this study was to analyze lower limb muscle activity and 3D motion analysis according to change foot arch height during walking. We selected 9 young and healthy people who have been normal foot. And we selected 7 young and healthy people who have been flatfoot. So, people were divided into 2 groups and walked platform during 2 minutes twice for checked by 3D motion analysis. These data were characterized by EMG measurements of three muscles( tibialis anterior, medial and lateral gastrocnemius) while they were walking. The collected data were analyzed by Independent t test using the SPSS statistics program(Ver 12.0). In foot arch change, there were no significant difference in three muscles 3D motion analysis also found that there were no significant difference in joint angles. In this study was to analyze lower limb muscle activity and 3D motion analysis according to change foot arch, but there were no significant difference in 6 muscles neither joint angles.

This research was attempted to seek for a positive approach within the framework of physical therapy instead of the drug treatment in the past, with regard to the ischemic brain injury in the early stage. Accordingly, the aim of this research is to observe the change of HSP27 and HSP70, the genes that are expressed in the early stage of brain injury and to investigate the effects of needle electrode electrical stimulation(NEES), upon applying NEES after ischemia. The experimental method is to give rise to global ischemia and apply NEES to 27 SD-Pat rats with the particulars of being eight-week-old, male, around 300g, and adapted to laboratory environment for more than a week, and divide them into three groups, that is, GV20 NEES group(n=9), L14 NEES group(n=9), no applied NEES global ischemia(GI) group(n=9), and then observe their changes of HSP27 and HSP70 at the time lapse of 6, 9 hr and 12 hr after ischemia, using immunohistochemistry methods. Upon observing through the immunohistochemistry method, it was noticed that there was a significant difference between the GV20 NEES group and the L14 NEES group as for HSP27 and there were significant differences among all groups as for HSP70(p<.05). Accordingly, it is supposed that the application of NEES after the outbreak of cerebral ischemia delay the apoptosis in the early ischemic part of forebrain or protect neurons against apoptosis.

This study was to examine on the respiratory variables, heart rate and muscle activity between the static recovery and dynamic recovery after progressive resistance exercise to maximal point. Subjects were 15 students enrolled in N University. All were tested two times (static recovery and dynamic recovery) and were requested to perform a walking on a treadmill after progressive resistance exercise to maximal point. Electromyography(EMG) was used to monitor the muscle activity(TA: Tibialis Anterior, MG: Medial Gastrocnemius) during gait. CPEX-1 was used to measure the respiratory variables and heart rate. The dynamic recovery group was shown the significant lower heart rate than that of static recovery group at during gait. Respiratory rate showed statistically a significant difference. Electromyography(RMS, root mean square) showed a non-significant difference. But the dynamic recovery group of muscle activity was found highly in TA and MG. This study indicated that the dynamic recovery method evidenced more faster than the static recovery method. And this type of dynamic rest by walking can be a help of recovery after exercise.

봄수확 수삼의 항공 및 선박의 모의수출 유통 중 손실유형을 조사하기 위해 수삼을 기능성 LDPE 필름에 5 kg 대포장 또는 500 g 소포장으로 포장하고 각기 다른 모의수출 유통 온도 및 모의수출 기간 즉 항공 모의수출 유통은 15℃와 25℃로 설정된 저장고에 4일 동안 저장하고, 선박모의수출 유통은 1℃와 5℃로 설정된 저장고에 14일 동안 저장한 뒤 유통실험을 위해 최종 10℃로 설정된 저장고에 수삼을 옮기고 수삼의 품질 변화를 조사하였다. 수삼의 품질 조사는 포장단계부터 10℃유통기간까지 총 기간 수행하였다. 조사결과 수삼의 유통 중 손실률에 가장 크게 영향을 미치는 것은 물러짐과 곰팡이 발생에 의한 부패로 나타났다. 물러짐과 곰팡이에 의한 부패를 합한 종합 손실률에서 손실률 20%를 유통한계 기간으로 정했을 때 항공 모의수출유통 조건인 25℃에서 5 kg 대포장은 10일, 500 g 소포장은 6-7일에 20%에 도달했으며, 15℃는 5 kg 대포장은 17일, 500 g 소포장은 12-13일에 20%에 도달했다. 선박 모의유통 조건인 5℃는 5 kg 대포장은 21일, 500 g 소포장은 28일경에 20%에 도달했고, 1℃는 5 kg 대포장은 24일, 500 g 소포장은 29일 경에 20%에 도달하는 것으로 나타나 수삼의 유통은 모의수출 유통 방법뿐 아니라 포장용량도 손실률에 상당한 영향을 미치는 것으로 나타났다. 수삼의 부패에 관여하는 병원균 중 곰팡이 균은 대부분Fusarium sp., Botrytis sp., Penicillium sp. 균들로 동정되었고, 25℃에서는 Fusarium sp. 균이 우세종이고, 그 이하의 온도에서는 Botrytis sp. 균이 우세종으로 나타났다.

The spermatogenesis is the process by which spermatozoa are generated in the testes. The spermatozoa travel male reproductive tract during which they meet many substances secreted from reproductive organs. One of the substances is epididymal protease inhibitor (EPPIN) that is involved in the post-testicular maturation including capability of fertilizing the eggs. The expression of EPPIN gene was investigated in various tissues of sexually mature and regressed male Syrian hamsters by reverse transcription polymerase chain reaction (RT-PCR). The EPPIN gene was identified in the testis and epididymis of the male Syrian hamsters and compared to the genes reported previously. There was no expression of EPPIN gene in reproductively and completely regressed testes of Syrian hamster. These results suggest that the expressions of the EPPIN gene are associated with the reproductive capability in the Syrian hamsters.

As an aquaculture effluent is recognized as a source of water pollution, many methods are being researched to solve this problem. It has been reported that the aquaculture effluent contains many organic compounds containing nitrogen, phosphorus, potassium, and calcium. The purpose of this study was to investigate the possibility of using the effluent from bio-floc technology (BFT) inland aquaculture for fertilizing blueberry ‘Duke’ to promote the growth. The experiment was conducted in a commercial blueberry farm in Jinju, Gyeongsangnam-do, where blueberries are actually cultivated in order to find out the effects of fertilizers in situ. The experiment was carried out with five treatments: control with only irrigation, conventional nutrient solution fertigation, and the fertigation with three concentrations (×1, ×0.5, or ×0.25) of effluent from BFT (Bio-Floc Technology) inland aquaculture. The treatment period was from the beginning of April, when a new leaf of blueberry began to develop, to the middle of June, when the blueberry was harvested, for a total of 10 weeks. As a result of the experiment, the treatments with effluent from BFT inland aquaculture showed better growth qualities than those of control and conventional cultivation. However, there was no statistically significant difference among all treatments regarding the total fruit production. Based on these results, it was concluded that the effluent from BFT inland aquaculture can be used for the cultivation of blueberry because it is equivalent to conventional cultivation method. This study provided a new viewpoint of recycling the effluent from BFT for agricultural purpose to reduce water pollution problems due to aquaculture wastewater.

As the interest in urban agriculture and people’s demand for eco-friendly food grow, the number of urban gardeners who directly grow and harvest will increase. The aim of this study was to compare the effect of conventional fertilizer with the effluent water from the biofloc technology inland aquaculture in the concept of resource circulation as a substitute for fertilizer used in urban agriculture. In order to verify the effect of fertilizer on the cultivation of cherry tomato, tomato seedlings were transplanted on the horticultural soil without nutrients and treated for 8 weeks. Experimental treatment was carried out in five treatments: control, hyponex solution (HS), slow-released fertilizer (SF), effluent water daily treatment (DE), and effluent water treatment once a week (WE). The growth characteristics of the cherry tomatoes showed significant differences among the treatments except for root length. In the case of plant length was shown HS=WE›DE=SF›control, and stem diameter was shown DE=SF ›WE=HS›control. It was found that HS and WE were not significantly different in shoot length and diameter, and DE and SF showed no difference. In the case of number of leaves, HS, DE, and WE showed a significantly higher level than SF and control. In other growth characteristics, DE and SF showed higher growth. As for the growth of cherry tomato fruit, the sugar content did not show any significant difference among the treatments except control. Weight per fruit and yield were significantly higher in HS and WE than DE and SF. Based on these results, it is considered that the use of effluent water is comparable to the use of urban agricultural fertilizer as compared with chemical fertilizers in cultivating crops.
