PURPOSES : This study is to suggest future development direction and application of environmental noise barriers as multi-functional soundproof wall. METHODS : Based on the literature review, case study and patent search, research and patent trend were investigated. Patent search was conducted by Patent searching tools, 'Focust'. RESULTS : As environmental noise barriers, Vegetative soundproof wall, photovoltaic soundproof wall, and air-pollution reduction soundproof wall were investigated. First of all, In Korea, Vegetative soundproof wall is being developed mostly as soundproof wall that has vegetation foundation inside, to meet the domestic condition with 23 patent applications. Second, Photovoltaic soundproof wall is being developed mainly with efficiency of photovoltaic system rather than soundproofing. And it is limited to one generation solar cell technology, although Solar cell technology is developing at a rapid pace. On the other hand, for reducing air-pollutant by soundproof wall, a variety of methods are being suggested (filtration, adsorption, and photocatalytic oxidation), and one of them, adsorption are applied for developing air pollution reduction soundproof wall in Korea. CONCLUSIONS: The above soundproof wall is not simple structure, but road facility applied fusion technique. Therefore, as one system, it is difficult to harmonize due to various considerations for design factor. However, if it's possible that a benefits of one system apply to another system, Synergy effect may be created. In the foreseeable future, soundproof wall may be considered as a road system using fusion technique rather than just functional facility. Therefore, substantial studies for applying multi-functional soundproof wall on the road are needed for the future.
Objectives : Recently the number of obesity population has grown, the idea recognizing obesity as an obvious disease which needs medical treatments has increased too. Obesity has become a rising and serious issue of public health in many developed countries. In this study, analyzing 15 recent Chinese research papers written about obesity treatment, we tried to understand the recent trend in obesity treatment in China; and examine the special features and curative rates of their treatment. Methods : We searched recent research papers which was related to obesity. Search pool includes 9198 papers on 5 Chinese journal, 2302 papers on zhongyizazhi(中醫雜誌), 1826 papers on zhongsiyijehezazhi(中西醫結合雜紙), 2389 papers on xinzhongyi(新中醫), 1069 papers on shanghaizhongyiyazazhi(上海中醫藥雜紙), 1612 papers on zhejiangzhongyizazhi(淅江中醫藥雜). First, we searched with the term '肥'. Among the search results, we selected the papers containing the term '肥滿' or ', and excluded the other papers which had no direct relation to obesity.(e.g., ' '肥厚性' etc.) In this way, 21 papers were selected, 18 papers satisfied our study object. Among them we adopted 15 clinical papers for our study, excluding 3 experimental papers. Results : Acupuncture therapy; the rate of excellent curative effect ranges from 9.4% to 77.8%, that of curative effect from 68.7% to 94.3%. Herbal therapy; the rate of excellent curative effect ranges from 6.5% to 52.3%, that of curative effect from 72% to 93.8%. Combined method; the rate of excellent curative effect is 44.8%, that of curative effect 83.5%. Conclusions : These results provides evidence that acupuncture therapy is the most effective among acupuncture therapy, herbal therapy and combined method in treatment of obesity. In addition, acupuncture therapy that uses a small number of acupoints and strong stimulation is more effective than any other therapies.
Objectives Obesity is one of the most important health problem in modern society and constant studies are still in progress domestically without the effective treatment so far. The objective of this study is to analyze the recent trend of the studies about obesity in oriental medicine and to provide background for further studies. Methods All of the articles in the journal of 'Korean oriental association for study of obesity' were collected published after 2006. Search were conducted through 'http://oasis.kiom.re.kr' and the journal of 'the Korean academy of oriental rehabilitation medicine'(January 2006~October 2010) with the search word "obesity". Collected articles were classified into clinical study, experimental study, literary study, case report. Results Total 177 articles were analysed. The number of studies were increasing until 2008 and went down afterwards. According to the classification by the type of study, percentage of clinical study took 45.2%, experimental study took 31.6%, literary study took 14.7%, case report took 8.5%. Conclusion Domestic clinical studies and experimental studies are conducted more focused on the treatment and diagnosis of obesity. Future study on the obesity should be focused on the prevention in the aspect of public health and social cost.
A valuation of air pollution is critical for relevant policy-making for the public and research direction. This study conducted a willingness-to-pay (WTP) survey using contingent valuation method (CVM) in Seoul Korea. In detail, this study puts an emphasis on its temporal changes referred on two surveys conducted in 2014 and 2019. In reference to the previous studies in 2002, our survey indicated that the public awareness of air pollution and interests on its sources and solutions increased noticeably. Our survey showed that WTP increased significantly from 2588 to 4827 and 8240 Korean Won $month^{-1}$ in 2002, 2014, and 2019, respectively. Moreover, the percentage of respondents to pay the WTP also increased from 48% to 68% and 79% in 2002, 2014, and 2019, respectively. Our analysis based on the number of Google search on particulate matters (PMs) strongly suggests that such the noticeable increases of the public attention to air pollution is well accorded with the moment of the announcement of a standard for ultra-fine particles and the start of PM prediction in late 2013. But the Google search rate grew about 16.7 times in 2009 compared to 2014, which is much larger than the growth rate of interest and WTP between 2014 and 2019. Our results shed light on policy decision for the right person in the right place on the right time in the era of air pollution.

Purpose : Until recently, the number of cancer patients continues to increase, and these patients have many limitations in their activities of daily living. In the republic of Korea, cancer patients are showing an increasing trend every year. Cancer disease not only significantly reduces the quality of life in individuals, but also causes various side effects if not managed. The purpose of this study was to investigate the effects of aerobic exercise and resistance exercise on health-related problems in cancer patients. Methods : This study searched for studies that applied aerobic exercise and resistance exercise to cancer patients reported in search engines (google scala, dbpia, and pubmed) from 2017 to 2022. Six randomized controlled trials and two systematic reviews and meta-analyses were used for analysis in our study. "physical activity", "exercise", "aerobic exercise", "resistance exercise", and "cancer patient" were the main search terms. The data included aerobic exercise, resistance exercise, cancer patients' muscle strength, physical strength, quality of life, and physical activity. Results : According to the eight studies that met the criteria included in this review study, it was found that aerobic exercise and resistance exercise had an effect on the increase in physical fitness, muscular strength, quality of life, and range of motion in cancer survivors. Conclusion : It was confirmed that aerobic exercise and resistance exercise are safe and effective interventions that can be applied to cancer patients without side effects. A limitation of this study is that it did not examine cancer diseases in various population groups such as the elderly and children. Therefore, in future studies, studies that consider specific details such as age, gender, type of cancer, and physical differences are needed.

This study investigates the influence of particulate matter concentrations on the incidence of asthma, focusing on the delayed onset of symptoms and subsequent medical consultations. Analysis incorporates a four-day lag from the initiation of fine dust exposure and compares asthma patterns before and after the World Health Organization's (WHO) classification of fine dust as a Group 1 carcinogen in November 2013. Utilizing daily PM10 data and asthma-related medical visit counts in Seoul from 2008 to 2016, the study additionally incorporates Google search frequencies and newspaper article counts on fine dust to assess public awareness. Results reveal a surge in search frequencies and article publications after WHO announcement, indicating heightened public interest. To standardize the long-term asthma occurrence trend, the daily asthma patient numbers are ratio-adjusted based on annual averages. The analysis uncovers an increase in asthma medical visits 2 to 3 days after fine dust events. Additionally, greater public awareness of fine dust hazards correlates with a significant reduction in asthma occurrence after such events, even within 'normal' fine dust concentrations. Notably, behavioral changes, like limiting outdoor activities, contribute to this decrease. This study highlights the importance of analyzing accumulated medical data over an extended period to identify general public behavioral patterns, deviating from conventional survey methods in social sciences. Future research aims to extend data collection beyond 2016, exploring recent trends and considering the potential impact of decreased fine dust awareness amid the COVID-19 pandemic.

Objective : For activation of study on filed of odontology in Korean medicine academia, we analyzed the trend of articles that published in journals of Korean medicine. Methods : Using search words of odontology, in internet reference sites we collected papers and classified those into three categories like as review article, original article, case report. Observation points of each item are as follows. Inclusive item of papers; publication year, journal, number of authors, disease. Item of review article; subject of paper, Item of original article; number of patients, period of research, remedy. Item of case report; remedy, valuation of criteria, number of cases. Results : The total number of articles searched was 88, consisting of 23 review articles, 46 original articles and 19 case reports. The percentage of 'TMJ diseases' ranked highest(47.7%) in classification by disease. The most reviewed subject was 'Remedy' (16 times). '25 or less' person ranked highest(50%) in the number of patient in original articles. Acupuncture, chuna manual medicine and herbal medicine were mostly applied in case reports. The number of 'one case' reported case reports was highest(52.6%).
There are several kinds of battery such as zinc-air battery, lithium battery, Manganese dry battery, silver oxide battery, mercury battery, sodium-sulphur battery, lead battery, nickel-hydrogen secondary battery, nickel-cadmium battery, lithium ion battery, alkaline battery, etc. These days it has been widely studied for the recycling technologies of the used battery from view points of economy and efficiency. In this paper, patents on the recycling technologies of the used lithium battery were analyzed. The range of search was limited in the open patents of USA(US), European Union(EP), Japan(JP), and Korea(KR) from 1986 to 2006. Patents were collected using key-words searching and filtered by filtering criteria. The trends of the patents was analyzed by the years, countries, companies, and technologies.
This study was performed to test the validity and reliability of the Health Self-Determinism Index for Children(HSDI-C), an instrument designed to measure dimensions and strength of motivation in health behavior, to improve the applicability of the tool through application to the various samples. The convenient sample of 148 (boys=75, girls=72 third grade=42, fourth grade=22, fifth grade=32, sixth grade=52 : Caucasian=72, Asian=30, African=19) comprised the children at a chatholic elementary school in Chicago. The children completed English version of HSDI-C from December 5th, 1994 to January l0th, 1995. The findings were as follows : 1. Four factors of HSDI-C were isolated through the principal component analysis and oblique rotation, and explained 48% of the variance in total score. Low correlations among four factors were anticipated because each factor contributed uniquely, All items of the tool loaded above .30 on one of 4 factors. But items loaded on each factor in this study were very different from those in the previous studies. 2. Cronbach's alpha coefficient for internal consistency was .81 for the total items and .57∼ .81 for 4 subscales. 3. The differences of HSDI-c mean scores between boys and girls and that of among races were not statistically signifcant, but the mean score of girls and the Caucasian were relatively high. The total mean score of the scale was highest at the 3rd grade, decreased at the 4th or 5th grade, and reincreased at the 6th grade. The trend of mean score of four subscales was similar to that of total mean score. According to the results, suggested below : 1. The items loaded on each factor in this study were very different from those in the previous studies. To clear away the problem of the conceptual confusion, HSDI-C needs to be performed to various and large samples. 2. Unexpectedly, the HSDI-C mean score decreased at middle school age. A longitudinal study will be helpful to search for the change trend of the intrinsic motivation. 3. To improve the applicabilty of the HSDI-C, various reliability and validity test methods besides factor analysis or internal consistency are recommended.
