Objectives: The aim of this review was to investigate whether evidence of complementary and alternative medicine (CAM) was reflected in clinical practice guidelines (CPGs) for insomnia based on relevant clinical trials. Methods: We conducted a systematic search on domestic and international CPG databases and medical databases. In addition, we conducted manual searches of relevant articles. Three authors independently searched and selected relevant studies; any disagreement was resolved by discussion. We extracted and analyzed the following data: published language, country, development group, participants, interventions, presence or absence of recommendations for CAM, level of evidence, grade of recommendation for CAM, and methods of development. Results: We identified 8,241 records from domestic and international databases, and 22 CPGs were included. Eleven of the 22 CPGs mentioned CAM interventions including herbal medicine, relaxation, acupuncture moxibustion, Tai Chi, meditation, hypnosis, biofeedback, Tuina, and external herbal medicine. However, most of the CPGs indicated 'no recommendation' or 'weak recommendation' for CAM interventions. Only Valeriana dageletiana Nakai and relaxation were considered to have experimental evidence. Valeriana dageletiana Nakai was recommended for improvement of sleep latency, sleep maintenance, total sleeping time, and sleep cycle. Relaxation was recommended as effective intervention for relieving physical and psychological arousal. Conclusions: Despite systematic reviews and randomized controlled trials on CAM for insomnia, most of the CPGs for insomnia did not reflect the evidence obtained. Further CPGs for insomnia should be developed by considering the current advanced studies in the field of CAM.

Objectives: This study was conducted to examine the prevalence and characteristics of savant skills and the relationship between the savant skills and autistic symptoms in Korean ASD children. Methods: 141 ASD subjects participated in this study and they were divided in to two groups based on the presence or lack of savant skills. The domain scores and total scores of the K-ADI-R, K-ASDS and SRS were used for evaluating the ASD symptoms between the groups. Results: Memory (N=47) was the most prevalent savant skill in the savant ASD group (N=60). The savant ASD group had a statistically higher mean age and IQ score than did the nonsavant ASD group. Despite their high IQ profile, the savant ASD group showed a higher restricted, repetitive and stereotype behavior score on the K-ADI-R and higher language and cognitive scores on the K-ASDS than did the nonsavant ASD group. Conclusions: These results suggest savant syndrome in ASD might be related to the severity of some subdomain of autistic symptoms even though their IQ scores were higher than nonsavant ASD patients.

Recently detection of early gastric cancer (EGC) has been increasing and the treatment strategies for gastric cancer have been changing. The purpose of this study was to compare clinical outcomes between laparoscopically assisted (LADG) and hand-assisted laparoscopic gastrectomy (HALDG) and open distal gastrectomy for early gastric cancer. This review is directed toward providing gastric surgeons with recent advances in the treatment of EGC. We investigated the English language literature for the past 12 years through computer searches which focused on : 1) Patient demographics, 2) Operation time, 3) Intra-operative blood loss, 4) Depth of invasion, 5) CBC, 6)Weight loss, 7) Analgesic requirement, 8)Time NPO, 9) Length of hospital stay, 10) Tumor stage, 11) Lymph node (LN) dissection, 12) Position of LN resected, 13) Complications. Improved operative techniques and surgical instrumentation have facilitated the development of minimally invasive gastric cancer surgery. The short-term benefits of laparoscopic gastrectomy included less surgical trauma, less pain, rapid return of gastrointestinal function, and shorter hospital stay, with no change in operative outcome. Laparoscopic gastrectomy was better accepted by the patients as a good procedure and promptly brought the patients back to their previous lifestyle and activities of daily living. But the advantages of HALDG for gastric cancer, extended lymph node dissection and intracorporeal anastomosis are feasible and easier with the presence of the internal hand. The hand-assisted laparoscopic (HALDG) method reported the best results in lymph node dissection.This method is an alternative to total laparoscopic radical gastrectomy. LADG and HALDG, when compared with conventional open gastrectomy, have several advantages. When performed by a skilled surgeon, LADG and HALDG are safe and useful techniques for patients with early-stage gastric cancer. Their appropriateness for gastric cancer surgery require further study.

China's cultural diplomacy is mostly understood as an endeavour to build and project soft power, which draws on three sources of 'culture, political values and foreign policy' according to Nye. This paper focuses on the debates about the vehicle and agents of China's cultural diplomacy. It starts with a theoretical discussion of the competing views in the Chinese context, and develops an argument that the vehicle of China's cultural diplomacy tries to project soft power on two wheels of culture and political values, to serve the purpose of reshaping China's image away from being the 'cultural other' and 'ideological other' respectively. However, the state-led approach to driving this vehicle is generating some side effects with its sponsorship, censorship and presence in the driver's seat. Then the paper analyses the inherent tensions existing in practice both between the two sources of building soft power and between the two means of doing so, attraction and persuasion, with empirical evidence through a comparative case study of the Confucius Institutes in the US and South Korea. The finding shows that China's attempt at reshaping its image as an Eastern cultural contestant is often disrupted by its authoritarian political values, and the state-led persuasion is often reducing China's cultural attraction. Following this, the paper finishes with some recommendations regarding evolving the cultural diplomacy approach from a vertical one that is government-centred to a horizontal one that is network-based with multiple agents, and localising its practice by engaging the target audiences as stakeholders.

In this paper, a low-cost impedance spectroscopy system(LCISS) suitable for modeling the electrochemical power sources such as fuel cells, batteries and supercapacitors is designed and implemented. Since the developed LCISS is composed of simple sensor circuits, commercial data acquisition board and LabVIEW software, a graphic language with powerful HMI(Human-Machine Interface), it is expected ta be widely used in substitution of the expensive EIS instruments. In the proposed system, the digital lock-in amplifier is adopted to achieve the accurate measurements even in the presence of the high level of noises. The developed hardware and software is applied to measure the impedance spectrum of the Ballard Nexa 1.2kW proton exchange membrane fuel cell stack and an equivalent impedance model is proposed based on the measurement results. The validity of the proposed equivalent circuit and the developed system is proven by the measurement of the ac power losses of the PEM fuel celt stack by the ripple current.

The growth of the algae strain Chlorella vulgaris under mixotrophic conditions in the presence of saccharified acorn-starch (acorn-glucose) was evaluated with the objective of increasing biomass growth and triacylglycerols (TAGs) content. The results indicated that 81.3% of starch was converted to glucose in acorns. C.vulgaris algal strains grown with acorn-glucose produced higher biomass and TAGs content than with autotrophic growth. The highest biomass production and TAGs content with 3 g/L acorn-glucose were 12.44 g/L and 32.9%, respectively. Biomass production with 3 g/L acorn-glucose was 16.4 fold higher than under autotrophic growth condition. These findings suggested that 3 g/L acorn-glucose is economic and efficient for biomass production/productivity and TAGs content of microalgae. This study provides a feasible way to reduce the cost of bioenergy production from microalgae.

Unlike face-to-face communication, text-based communication by digital media has limitations that non-verbal elements are eliminated and social presence decrease. To overcome this problem, people try to find solutions which visualize emotion and situation by using emoticons, icons, computer language and so on. As most SMS users experience the failure of using emotions on the mobile phone, they need to make up for this point. In this study, we conducted research on the recent mobile fonts situations and surveyed users' perception on SMS fonts as to suggest solutions of expressing and visualizing emotions on the mobile phone, a representative media of personal communication. As a solution of reducing the failure, we conducted a survey on users' perception about fonts and the capability of the expressing emotions by fonts. The survey found that mobile fonts can be used as a method to express human emotion. As a finding, the shape of the font can be used as a method to visualize the emotion through text messaging. In future studies, such a method can be applied to variety of different personal media with the communication method based on text. Those studies can propose different usage for fonts in communication.

Jeongun(丁芸) Lee, Young-do (李永道), who is deemed a representative female poet of Korea, began her literary career in May, 1946 when she published in a publication called "Bamboo Sprout, (죽순)". Her Korean identity, which was formed through her Confucius upbringing as well as traditional value system of her family, had a strong presence in her work, and she remained a quintessential figure in Korea's female sijo poet circle for 30 years until her passing in 1976. Despite the highly acclaimed talent and her noble aspirations, it is undeniable that her works did not receive fair assessment due to her private life. Against this backdrop, it is necessary to deeply inquire the literary values and beauty of Young-do Lee's sijo. As mentioned, Young-do Lee is a solidly established figure in Korea's modern poetry. The following illustrates the spirit and the world of her poetry. First, Young-do Lee lived through turbulent times and it was her country that served as the source of her sijo work. Assessing the multitude of dramatic historical events such as Japanese colonization, 8.15 Liberation of Korea, division of the nation, 6.25 Korean war, 4.19 Revolution, 5.16 military coup, it is natural that patriotism was strongly present in her work who was one of the intellectuals at the time. Second, Young-do Lee is a poet who had experienced more pain than others in terms of the turbulence of the time. Her Korean identity, which was formed through her Confucius upbringing as well as traditional value system of her family, had a strong presence in her work. Third, Jeongun Lee, Young-do is a poet of longing. The abundance and richness of her emotions were fortified through the relationship with another poet, Chihwan Yu. Fourth, Young-do Lee is a poet opened up new horizons for the modennization. The transparency of image reflected in her work and the elaborate nature of her language are outstanding. In summary, Young-do Lee was a true artist, who has a strong presence in Korea's modern poetry society, and who was a poet of patriotism, poet who suffered the turbulence of the times, and a poet of longing.

The purpose of this study is to (evaluate) the effectiveness of neurofeedback training (NFT) and systematically search for the related factors by conducting a meta-analysis of theses and journal articles published in (the Korean language/Korea). This study analyzed 21 articles selected through a database search from 2001 to 2015. The quality evaluation result of the research, as research method characteristic, was low. It was found that, first, the effect size of the neurofeedback program training was .683 above the (median). Second, the effect size as the (moderator) variable played a statistically significant role in moderating the effect of the the subject characteristics, including the presence or not of disabilities and school level (elementary, junior high school, high school), on the effectiveness of the neurofeedback training program. Third, (the effect size) played a statistically significant role in mediating the effect of the research method (training method), number of sessions per week, total number of sessions and training time on the effectiveness of the neurofeedback training program. This study provides (comprehensive) data on the effect of the interventions and selection of the neuro-feedback training program subjects.

This study investigates non-native speakers(NNS) of English use of backchannels with beginner-intermediate learners' use of 'uh', 'um(uhm)', 'and' and 'hm' suggesting a view as a possible pedagogical implication. The initial aim of this study was to learn this phenomenon and observe their conversation patterns to compare with previous studies. Based on the previous findings, the analyzed data using conventional Conversation Analysis (CA) methods indicate the possible presence of L1 topic markers, '-un' and '-nun' in the form of L2 backchannel tokens when uttered by beginning and intermediate level speakers of English and the presences of L2 backchannel tokens appear only in front of noun phrases. Additionally, these same words with these tokens and when translated back to Korean also require topic markers of '-un' and '-nun.' Finally, This study discusses possible pedagogical implications with the initial analysis of backchannel tokens for Korean EFL learners. In addition, the ultimate goal of this study is to refine this analysis with follow up experiments to validate this investigation into a working hypothesis generating discussions of this backchannel phenomenon from being viewed as a hindrance to as an positive influence that needs to be understood.
