Objective: This study is to investigate the effect of real-time feedback from the therapist on posture, muscle strength, pain of subjects with forward head posture based on a non-face-to-face complex exercise program. Design: Two-group pretest-posttest design. Methods: Thirty healthy men and women in their twenties with forward head posture with a Craniovertebral angle of 52° or less were targeted, the final selection was made as 15 experimental groups who performed the non-face-to-face intervention program while receiving real-time feedback and 15 control subjects who performed the non-face-to-face intervention program without providing feedback. Six of them were eliminated, and a total of 24 were conducted as subjects. All exercise groups performed an exercise program three times a week, 30 minutes each, for a total of two weeks. Before and after exercise, Craniovertebral angle (CVA), CranioRotation angle (CRA), muscle strength, and tenderness threshold were evaluated. Results: Significant differences were shown in both groups in CVA, and tenderness threshold before and after exercise (p<0.05), and CRA, the left middle trapezius muscle strength, only in the experimental group (p<0.05). In the comparison of theamount of change between exercise groups, the group that received feedback on CVA, CRA and tenderness threshold showed a significant change than the group without feedback (p<0.05). Conclusions: As a result of this study, it can be seen that the therapist's real-time feedback is more effective in improving the forward head posture. This requires feedback from the therapist on posture correction during non-face-to-face exercise intervention.

As the online shopping market grows, channels in the mobile shopping environment have become increasingly diverse as a wide variety of products are introduced every day. This study investigated the effects of the self-construal type, mobile product recommendation system type, and fashion product type on purchase intention. The experimental design of this study was a 2 (self-construal type: independent vs. interdependent) × 2 (product recommendation system: bestseller vs. content-based) × 2 (fashion product type: utilitarian vs. hedonic) 3-way mixed ANOVA. Women (n = 387) in their 20 to 30s residing in Seoul and the Gyeonggi area participated in the study. The data were analyzed with the SPSS 24 program and 3-way ANOVA and simple main effects analyses were conducted. The results were as follows. First, self-construal, product recommendation, and fashion product types had a statistically significant impact on purchase intention. Second, fashion product and consumers' self-construal types had significant interaction effects on purchase intention. Finally, product recommendation and fashion product and self-construal types showed significant 3-way interaction effects on purchase intention. The study confirmed an interaction between the self-construal, type of product recommendation system, and the type of fashion product used in influencing purchase intention.

Controlling fashion waste throughout the entire product lifecycle is critical in a circular economy. This study explored the possibility of establishing a public recycling system for fashion waste. Since consumer interests and participation are essential, theoretical research, social-text analysis, and quantitative research were conducted to identify consumers' perceptions of the public recycling of fashion waste and circular fashion. Data were collected via an online survey among women in their 20-30's living in Korea, and 304 samples were used for data analysis. The results were as follows. First, consumers' perceptions of recycling fashion waste were composed of recycling difficulty, the need for public recycling, and the need for EPR. Circular fashion perception comprised favor, environment protection, attractiveness, economics, quality and hygiene risks, and lack of diversity. Second, the reuse-recycle attitude and need for EPR affected the favor of all types of circular fashion products. Third, environmental concerns impacted attractiveness, and the favor significantly affected the purchase intention of all types of circular fashion products. In particular, quality and hygiene risk negatively affected the purchase intention of used-fashion products, while attractiveness positively impacted the purchase intention of upcycled-fashion products. The results implied that discussing the public recycling system of fashion waste and EPR policy is imperative. The results also showed the need to classify different types of circular fashion products, such as used, upcycled, and regenerated fashion items, to examine consumers' perceptions. In addition, the recycling of the fashion waste scale developed in this study could be used for further research.

The cotton, wool, cotton/wool blended(80:20) and tencel fabrics were treated with low temperature oxygen or argon plasma, enzymes(cellulase or protease), or oxygen plasma-enzyme and examined for their weight loss and conditions for treatment for the environment friendly finishing. In the plasma treatment argon gas had better effect on the weight loss than oxygen gas did and the weight loss of all the fabrics was increased as increasing discharge power and discharge time. The weight loss of cotton, wool, cotton/wool blended(80:20) fabrics decreased in a large measure after 1 hr but that of tencel didn't decrease after 1 hr. In case of cellulose fibers oxygen gas plasma induced chemical functional groups on the surface of substrate more than argon gas plasma did so the weight loss of wool was larger than that of cotton, tencel fabrics in oxygen plasma-enzyme treatment. The weight loss of cotton and tencel fabrics decreased the initial stage because oxygen plasma pre-treatment caused cross linking as well as etching effect but argon plasma pre-treatment didn't. The plasma pre-treatment cleared the way for enzyme treatment on the whole but oxygen plasma pre-treatment bear in hand the increase of weight loss more or less because of the cross linking on the surface of cellulose fibers. The appropriate conditions for plasma treatment was 10-1Torr, 40W for 30minutes and for cellulase treatment were enzyme concentration of $3g/{\ell}$, pH 5, $60^{\circ}C$ for 1hr and for protease treatment were enzyme concentration of $4g/{\ell}$ pH 8, $60^{\circ}C$ for 1hr.

Endocrine disrupting chemicals (EDC) have been emphasized due to their threats in human health. Waste incinerator emission has been emphasized as a source of EDC including polychlorinateddibenzofurans(PCDD/F) and other carcinogenic polycyclic aromatic hydrocarbons (PAHs). Urinary 1-hydroxypyrene (1-OHP) has been used as an exposure biomarker for the PAHs. On the other hand, etheno-DNA adducts, e.g. 1, $N^6-ethenodeoxyadenosine({\varepsilon}dA)$, has been developed as an useful effective or response biomarker for carcinogenesis. Thus, I investigated association between urinary 1-OHP and ${\varepsilon}dA$ levels due to distance from an incinerator which was built more 10 years ago in the middle of a farm in P city. I designated the EDC-high and low exposed group due to distance from the incinerator, i.e. within 2.5km and $5.0{\sim}7.5km$ from the incinerator, respectively. The study subjects were age and sex-matched males and females (mean age, $61.3{\pm}9.6$ yrs; total 40 persons, male, 10; female, 10 for the each group). Urinary 1-OHP and ${\varepsilon}dA$ were analyzed with HPLC-FD and IP-HPLC-FD, respectively. As results, the distance from the incinerator was not associated with urinary 1-OHP nor ${\varepsilon}dA$ levels (p=0.43 and 0.82, respectively). On the other hand, urinary ${\varepsilon}dA$ levels were significantly higher in the hyperlipidemia group (N=10) than normal group (N=30). In conclusion, urinary 1-OHP nor ${\varepsilon}dA$ levels can not be suggested as an incinerator-related exposure nor effective biomarker. However, not only distance from the incinerator bot also systemic approaches including wind and soil contamination are required to assume exposure levels of incinerator-related EDC.

A survey of nutrition and incidence of parasites was conducted from January 23 to 31 and February 14 to 18, 1981, to determine the nutritional status of young children under the age of 6 years, in one of the rural family health project areas: Whaseoung-gun, Kyunggi-do, Korea. This study covered a total of 233 children. The results are summarised as follows: Approximately one-half of these families had an annual income between \1,000,000 and \2,500,000. Nearly 84% of the households were involved in farming. Energy intake of children met 70.6% of the requirement: carhohydrates provided 77%, protein provided 11%, and fat provided 12% of the total energy intake. Low intake of iron; calcium; and vitamins, excluding thiamin, was also found. Mean hemoglobin value was $10.6{\pm}1.0gm/100ml.;\;42%$ of subjects were categorized as low group, 22% were in the deficient group, and only 36% were at an acceptable level as indicated by O'Neal. Thus, 22% of the subjects were proven to be anemic by the hemoglobin criteria. Mean hematocrit value was $30.1{\pm}2.8%$, and 80 of 208 children, or 38.4% of subjects, were below 30% of the standard established by O'Neal. The positive prevalence of parasitic infection was 20% , significantly higher than that observed in the Yowido compound (5.5%) in 1980. Hematologic findings had no significant correlation to parasitic infection. The majority, 95.2% of the subjects, met or surpassed 90% of the KlST's standard of height:whtile 28. 6% of the subjects were below 90% of the KIST's standard of weight. The ratio of weight to height for boys 4 to 6 years old was 15.8 to 17.5, in contrast to 16.3 to 16.9 for boys of KHDI project areas, and also in contrast to 17.7 to 17.9 for boys of the same age group from the Yowido apartment compound in Seoul. According to the results of the assessments, the authors found a clear difference in growth values, hematologic findings and dietary patterns between rural areas and advantaged urban areas of Seoul. Our results suggest the need to develop the nutrition and parasite control training of village women for better nutritional care of their young children.

사대부들의 전유물인 시조에서 신선은 어떤 역할과 정체성을 가지고 있는가를 고찰하였다. 시조에서 선어들이 빈도수가 많음을 기존의 연구사를 통해 밝혔고 시조라는 장르를 통해서는 신선에만 집중하였다. 그중 적송자가 많이 등장하는데 적송자는 사대부들이 좇아가는 적송자로 표현하고 있어 '적송자를 좇으리'가 관용어구처럼 쓰이고 있다. 이것은 적송자를 좇아야만 비로소 신선 대열에 낄 수 있다는 등식처럼 되어버린 결과다. 중국의 장량이나 범려도 부귀영화를 다 버리고 적송자를 찾아 신선이 되어 영원 불사했다는 역사적 사건이 변모되어 전설로 신화로 이어지는 과정에서 시조를 즐기는 사대부들도 마치 장량이나 범려처럼 자신들도 적송자를 좇겠다는 관념어적인 어투로 쓰이고 있음을 알 수 있다. 그런가하면 이태백은 한국문학과 뗄레야 뗄 수 없는 인물이다. 태백은 시선이며 주선으로 시조 문학에서는 비상 모티브를 가진 신선 또는 상천 모티브로 쓰이는 주선으로 노래 부르고 있어 풍류를 즐기는 사대부들에게 친근하게 인용되고 있음을 확인하였다. 반면에 부정적으로 쓰이고 있는 신선으로는 진시황과 한무제를 들 수 있다. 두 황제는 불로초를 찾고 봉래산을 찾은 인물로 현실정치에서는 실각한 인물이다. 뿐만 아니라 불로장생을 원했지만 뜻을 이루지 못한 인물이어서 사대부들은 그런면에서 이상적인 이상향은 없다는 다분히 현실적으로 다가가 유교사상에 입각해 현실에 만족하며 살자는 자족형으로 시조를 부르고 있었다. 따라서 두 황제의 역할은 부정적 이미지다. 시조에서 여선들도 등장하는데 그중 마고선녀, 서왕모, 무산신녀, 항아가 있다. 마고 선녀는 장수를 관장하는 할머니로 때로는 미녀로 쓰이고 있으며 서왕모는 불사약을 가지고 있는 신선으로 무산신녀는 운우의 정을 대변하는 미녀로 항아는 남편을 배반하고 외롭게 월궁에서 지내는 신녀로 표출되고 있다. 이들 선녀의 특징은 미녀이며 자상하고 섬세하며 애정시에 두루 나타나고 있음을 알 수 있다.

Background: The purpose of this study was to investigate the distribution of systemic diseases and medications in patients older than 65 years of age who visited the hospital for implant treatment, as well as to investigate basic information about surgical complications that may occur after insured implant treatment. Method: A total of 126 patients over 65 years of age were treated for implant surgery from October 1, 2013 to October 30, 2016. Electronic chart review was conducted to obtain medical records, which included sex, age, systemic diseases, medication(s) being taken, and control of the medications. Five patients were excluded due to lack of medical records giving information about systemic disease. Results: Of the 126 patients, 112 (88.9%) were taking medication due to systemic disease and 9 patients (7.1%) were not. The sex distribution was 71 women and 55 men and the highest proportion of patients were between 65 and 69 years old. The most common diseases were, from most to least frequent, hypertension, cardiovascular disease, diabetes, and osteoporosis. The drug groups that can cause major complications after dental treatment were classified as hemorrhagic, osteoporotic, and immunosuppressive agents, and were taken by 45 (35.7%), 22 (17.5%) and 4 (3.2%) patients, respectively. Conclusion: Given that 88.9% of the elderly patients who were eligible for insurance implant treatment had systemic disease, it is necessary to carefully evaluate patients' medical histories and their general conditions in order to prevent emergencies during implant surgery.

This study examines changes in walking ability among patients with stroke after applying dual-task training under the condition of visual control and unstable supporting ground; the purpose is to provide reference data for selecting intervention methods that enhance the walking ability of patients with stroke. Among the patients with stroke who received rehabilitation treatment(at Rehabilitation Hospital B in Gyeonggi, South Korea from May 2014 to July 2014), 29 patients were selected as research subjects; all of them understood the purpose and contents of this research and agreed to participate in the experiment. The research subjects were divided into a visual control and unstable supporting ground dual-task(VUDT) group(10 patients), a visual control dual-task(VDT) group(10 patients), and an unstable supporting ground dual-task(UDT) group(9 patients); all of the subjects received 30-minute trainings, three times a week for a total of four weeks. A Timed-Up-and-Go(TUG) test was performed to investigate the change of walking function among the subjects, and a 10m walking test was conducted to measure their walking speed. According to the study results, all three groups showed significant differences after dual-task training; the dual-task training group under the condition of visual control and unstable supporting ground showed the most prominent change. This study confirmed that dual-task training using visual control and unstable supporting ground has a positive impact on the walking ability of patients with stroke. Through the study results, we found that implementing dual-task training under the condition of visual control and unstable supporting ground can more effectively improve the walking ability of patients with stroke, rather than performing visual control dual-task training or unstable supporting ground dual-task training only.
