This study aimed to investigate whether mass drug administration (MDA) intervention has an equivalent effect on reducing the prevalence and intensity of Schistosoma haematobium infection regardless of the baseline values. A repeated cross-sectional survey was performed targeting students of 12 primary schools in Al Jabalain and El Salam districts of White Nile State, Sudan, at both 1 week before and 8 months after the MDA. Prior to the baseline survey, schoolaged children in Al Jabalain had received MDA interventions twice in 4 years, while those in El Salam had not. The baseline prevalence was 9.1% in Al Jabalain and 35.2% in El Salam, which were reduced to 1.8% and 5.5% at 8 months after the MDA, respectively. The corresponding reduction rates were 80.3% and 84.4%, not significant difference between both districts. However, changes in the geometric mean intensity (GMI) of egg counts were significantly different between both districts. The baseline GMIs were 14.5 eggs per 10 ml of urine (EP10) in Al Jabalain and 18.5 EP10 in El Salam, which were reduced to 7.1 and 11.2 EP10 after treatment, respectively. The corresponding reduction rates were 51.0% and 39.5%. In conclusion, MDA interventions were found to bring about similar relative reduction in prevalence regardless of the baseline value; however, the relative reduction in infection intensity was more salient in the district with a low baseline value for both prevalence and intensity. This clearly points to the importance of repeated MDA interventions in endemic areas, which will eventually contribute to schistosomiasis elimination.

Objectives : We investigated the efficacy and safety of miniscalpel acupuncture (MA) treatment combined with non-steroidal anti-inflammatory drugs (NSAIDs) for chronic neck pain (CNP) in an assessor-blinded randomized controlled pilot trial to establish a basis for larger-scale randomized controlled studies on this subject. Methods : Participants (n=36) were recruited and randomly allocated to the MA group, NSAIDs and combined treatment group. The MA group received MA three times over three weeks. The NSAIDs group was administered orally with zaltoprofen 80mg t.i.d. over three weeks. The combined treatment group received MA and zaltoprofen in the same manner as MA and NSAIDs groups. The primary outcome was pain as assessed by a visual analogue scale (VAS) and the secondary outcomes were assessed using the Neck Disability index (NDI), EuroQol 5-dimension questionnaire (EQ-5D), and Patients' Global Impression of Change scale (PGIC). Assessments were made at week 0 (baseline), 1, 2, 3 (primary end point) during treatment and at week 7 (4 weeks after the end of treatment). Results : 35 participants completed the study. No serious adverse event occurred and blood test results were within normal limits. The improvement of VAS and NDI was significantly greater in combined and MA group than that in NSAIDs group (p<0.017). The combined group showed better outcomes in EQ-5D at visit 2 and 5, in PGIC at visit 4 than the NSAIDs group (p<0.017). No significant differences were found between combined and MA group. Conclusions : Our results suggest that both combined and MA group can be more effective in improving pain control than NSAIDs group. A large-scale clinical study is warranted to further clarify these findings.

Objectives: Radon and its progeny pose environmental risks as a carcinogen, especially to the lungs. Investigating factors affecting indoor radon concentrations and models thereof are needed to prevent exposure to radon and to reduce indoor radon concentrations. The purpose of this study was to identify factors affecting indoor radon concentration and to construct a comprehensive model thereof. Methods: Questionnaires were administered to obtain data on residential environments, including building materials and life style. Decision tree and structural equation modeling were applied to predict residences at risk for higher radon concentrations and to develop the comprehensive model. Results: Greenery ratio, impermeable layer ratio, residence at ground level, daily ventilation, long-term heating, crack around the measuring device, and bedroom were significantly shown to be predictive factors of higher indoor radon concentrations. Daily ventilation reduced the probability of homes having indoor radon concentrations ${\geq}200Bq/m^3$ by 11.6%. Meanwhile, a greenery ratio ${\geq}65%$ without daily ventilation increased this probability by 15.3% compared to daily ventilation. The constructed model indicated greenery ratio and ventilation rate directly affecting indoor radon concentrations. Conclusions: Our model highlights the combined influences of geographical properties, groundwater, and lifestyle factors of an individual resident on indoor radon concentrations in Korea.
Purpose: To find objective validity of minimal acupuncture using a modified guide tube as a method to verify the effect of acupuncture. Methods: Subjects of this study were participants of a randomized clinical trial which was practiced to verify the effect of acupuncture on postmenopausal hot flash. There were 2 arms of treatment, one's for active acupuncture group(AG) with manipulation and De qi, the other's for minimal acupuncture group(MG) using a modified guide tube which was designed to give minimal stimulation to the patient. After 8 weeks' treatment followed by 4 weeks' observation, participants were asked to fill in self-report forms on their education, previous experiences of acupuncture, original idea on the efficacy of acupuncture and recognition of blinding. Results: 19 participants of 26 in AG and 19 of 26 in MG completed the self-report form. There was no difference between AG and MG in their education(p=0.5976, Fisher exact test) and previous experiences of acupuncture(p=0.9999, Fisher exact test). In their original ideas on the efficacy of acupuncture, most of AG and MG respondents have been thought that acupuncture is very effective or quite effective, and there was no difference between 2 groups(p=0.5065). 16 of 19 in AG and 14 of 19 in MG believed that they underwent more effective way, there was no statistical difference between 2 groups(p=0.6928, Fisher exact test). Participants believed in undergoing more effective way not because they recognized treatment method, but they were satisfied with the effectiveness of treatment retrospectively. Conclusion: As the result of this study, these authors suggest that minimal acupuncture using a modified guide tube is acceptable as a method to verify the effect of acupuncture in acupuncture-familiar Korean culture. Also further studies on the stimulation-specific effect of minimal acupuncture are demanded.

This study is to stabilize insoluble and unstable active ingredient which is Idebenone (INCI name: hydroxydecyl ubiquinone) in a multi-lamellar vesicle (MLV) and to stabilize it in the skin care cosmetics. Idebenone is good effective raw material in the treatment of Alzheimer's disease in the medical field and a powerful antioxidant in dermatology. It is well known as a substance that inhibits the formation of melanin and cleans the skin pigment. However, it did not dissolve in any solvent and it was difficult to apply in cosmetic applications. Niosome vesicle was able to develop a nano-particle by making a multi-layer of idebenone encapsulated with a nonionic surfactant, hydrogenated lecithin and glycine soja (soybean) sterols and passing it through a high pressure microfluidizer. Idebenone niosome vesicle (INV) has been developed to have the ability to dissolve transparently in water and to promote transdermal penetration. The appearance of the INV was a yellowish liquid having specific odor, and the particle size distribution of INV was about 10~80 nm. The pH was 5~8 (mean=6.8). This capsulation with idebenone was stored in a $45^{\circ}C$ incubator for 3 months and its stability was observed and quantitatively measured by HPLC. As a result, the stability of the sample encapsulated in the niosome vesicle (97.5%) was about 66.3% higher than that of the non-capsule sample of 32.5%. Idebenone 1% INV was used for the efficacy test and clinical trial evaluation as follows. The anti-oxidative activity of INV was 38.2%, which was superior to that of 12.8% tocopherol (control). The melanin-reducing effect of B16 melanoma cells was better than INV (17.4%) and Albutin (control) (9.6%). Pro-collagen synthesis rate was 128.2% for INV and 89.3% for tocopherol (control). The skin moisturizing effect was 15.5% better than the placebo sample. The elasticity effect was 9.7% better than the placebo sample. As an application field, INV containing 1% of idebenone is expected to be able to develop various functional cosmetic formulations such as skin toner, ampoule essence, cream, eye cream and sunblock cream. In addition, it is expected that this encapsulated material will be widely applicable to emulsifying agents for skin use in the pharmaceutical industry as well as the cosmetics industry.
Objectives: The objective of this study was to provide clinical evidence to support the use of a herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet (TWBXP)) for insomnia. Methods: Randomized controlled trials that verified effects of Herbal Medicine (Cheonwangbosim-Dan, Tianwangbuxin-Pellet) treating primary insomnia were carried out. A literature search of English, Chinese, Korean databases was also performed. The selected literature were assessed by Risk of Bias (RoB). Results: The total number of selected trials was 13 RCTs. Among the 13 RCTs, 10 were meta-analyzed. The Chinese Classification of Mental Disorders-3 (CCMD-3) was frequently used as the diagnostic criteria for interventions during the analysis of the use of herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet) for management of primary insomnia. As for outcome measurement, the effective rate was used. From the Meta-analysis of the studies, it was established that the insomnia cure effective rate in the TWBXP group was higher than that in the Western Medicine (WM) group (RR: 1.15, 95% CI: 1.07 to 1.24, p<0.0001, $I^2=33%$). Also, the effective rate in the TWBXP+ACU group was significantly different compared to the WM group (RR: 1.32, 95% CI: 1.13 to 1.54, p=0.0004, $I^2=0%$). The quality of the selected RCTs was low. Conclusions: Herbal medicine (Cheonwangbosim-Dan/Tianwangbuxin-Pellet) is effective for treating primary insomnia. It is worth noting that this studies were of relatively poor quality. The sample sizes were also small. Therefore, further investigations into the diagnosis and treatment of insomnia are warranted.

Objective : The purpose of this study is to analyze researches about sex education for children and adolescents with developmental disabilities in order to provide a basic data and a direction about sex education. Methods : For the systemic review, domestic and international research articles published from August 2008 to September 2018 were searched using the electronic databases PubMed, EBSCO host (CINAHL Plus with full text), Medline (ProQuest), RISS, and KISS. Keyword used for the search was 'Disability Disorder OR Autism (AND) AND (Effect OR Effectiveness)' for international papers and 'Disability AND Sex Education' for domestic papers. Total 15 articles were collected and analyzed in terms of participant, duration, type, contents, and teaching methods with PICO format. Results : In terms of level of evidence, majority was Level III evidence(60%). Most common contents of sex education were 'physical and growth' and 'relational skills'. Special education and occupational therapy were the field that sex education is provided most frequently. Effects of sex education identified were 'sex knowledge', 'sex attitudes', and 'inappropriate sexual behavior'. Conclusion : This study intend aimed to identify content, trends, and effects of sex education for children and adolescents with developmental disabilities in order to provide a basic data for clinical trial of sex education in occupational therapy practice. This study recommend further researches on the effects of sex education on occupational participation, occupational therapists' awareness of sexual activity of clients, and development of related measurement such as sexual development scale.
Objective: The aim of this study was to report the effectiveness of traditional Korean medicine treatment with rehabilitation exercise on a chronic intracerebral hemorrhage patient with a severe gait disturbance. Method: The patient was treated with Korean herbal medicine (Gami-sibjeondaebo-tang) along with acupuncture, moxibustion, and rehabilitation exercise. The treatment effect was evaluated through the Manual Muscle Test (MMT) and the Korean version of the Modified Barthel Index (K-MBI). The gait of the patient was evaluated by Functional Ambulatory Category (FAC) and the Timed Up and Go (TUG) test. The spatiotemporal parameters were evaluated by a walkway system (GAITRite(R) system) and gait symmetry was evaluated by Symmetry Criterion (SC). Results: After 111 days of traditional Korean medicine treatment, the spatiotemporal parameters and symmetry of the patient's gait improved. Conclusion: This study suggested that traditional Korean medicine treatment with rehabilitation exercise could be effective for gait disturbance in patients with chronic intracerebral hemorrhage.

Objective: This study evaluated the growth, digestibility and rumen fermentation between goats and sheep fed a fattening diet fortified with linseed oil. Methods: Twelve 3 to 4 months old male goats and sheep were randomly allocated into two dietary treatment groups in a $2(species){\times}2$ (oil levels) factorial experiment. The treatments were: i) goats fed basal diet, ii) goats fed oil-supplemented diet, iii) sheep fed basal diet, and iv) sheep fed oil-supplemented diet. Each treatment group consisted of six animals. Animals in the basal diet group were fed with 30% alfalfa hay and 70% concentrates at a rate equivalent to 4% of their body weight. For the oil treatment group, linseed oil was added at 4% level (w:w) to the concentrate portion of the basal diet. Growth performance of the animals was determined fortnightly. Digestibility study was conducted during the final week of the feeding trial before the animals were slaughtered to obtain rumen fluid for rumen fermentation characteristics study. Results: Sheep had higher (p<0.01) average daily weight gain (ADG) and better feed conversion ratio (FCR) than goats. Oil supplementation did not affect rumen fermentation in both species and improved ADG by about 29% and FCR by about 18% in both goats and sheep. The above enhancement is consistent with the higher dry matter and energy digestibility (p<0.05), as well as organic matter and neutral detergent fiber digestibility (p<0.01) in animals fed oil- supplemented diet. Sheep had higher total volatile fatty acid production and acetic acid proportion compared to goat. Conclusion: The findings of this study suggested that sheep performed better than goats when fed a fattening diet and oil supplementation at the inclusion rate of 4% provides a viable option to significantly enhance growth performance and FCR in fattening sheep and goats.
