We report 2 cases of Thelazia rhodesii infection in the African buffaloes, Syncerus caffer, in Zambia. African buffalo calves were captured from the livestock and wildlife interface area of the Kafue basin in the dry season of August 2005 for the purpose to translocate to game ranches. At capture, calves (n = 48) were examined for the presence of eye infections by gently manipulating the orbital membranes to check for eye-worms in the conjunctival sacs and corneal surfaces. Two (4.3%) were infected and the mean infection burden per infected eye was 5.3 worms (n=3). The mean length of the worms was 16.4 mm (95% CI; 14.7-18.2 mm) and the diameter 0.41 mm (95% CI; 0.38-0.45 mm). The surface cuticle was made of transverse striations which gave the worms a characteristic serrated appearance. Although the calves showed signs of kerato-conjunctivitis, the major pathological change observed was corneal opacity. The calves were kept in quarantine and were examined thrice at 30 days interval. At each interval, they were treated with 200 ${\mu}g/kg$ ivermectin, and then translocated to game ranches. Given that the disease has been reported in cattle and Kafue lechwe (Kobus lechwe kafuensis) in the area, there is a need for a comprehensive study which aims at determining the disease dynamics and transmission patterns of thelaziasis between wildlife and livestock in the Kafue basin.

Objectives: The purpose of the study was to investigate the influencing factors of oral health-related quality of life in social workers. Methods: A self-reported questionnaire was completed by 240 social workers in Gwangju by convenience sampling method. The questionnaire consisted of general characteristics of the subjects(age, monthly salary, smoking, alcohol consumption) and systemic health condition(systemic diseases, medication, oral health status, and stress). The factors associated with oral health-related quality of life included skin dryness, eye dryness, lip dryness, and nasal dryness. The subjective dry mouth consisted of 6 questions measured by visual analogue scale(VAS). Cronbach's alpha was 0.868 in the study. The data were analyzed for t-test, one-way ANOVA and multiple regression analysis using SPSS 18.0 program. Results: The oral health-related quality of life in social workers varied by age, oral health status, stress status, and halitosis. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The health status(${\beta}=-0.410$) had the influence on the oral health-related quality of life, nasal dryness(${\beta}=0.230$), age(${\beta}=0.189$), and halitosis (${\beta}=0.162) in order. Conclusions: The oral health-related quality of life was closely related to the health status and nasal dryness. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the social workers.

Minerals are extremely important in human metabolism, growth, and tissue repair. The risks of disturbances in mineral nutrition and metabolism are high following menopause. The aim of the study was to investigate the mineal nutrition status in middle-aged women (Pre & Postmenopausal) and the relation to climacteric symptoms. In the present study, we conducted the anthropometric measurement, climacteric symptoms survey and the dietary intakes including macronutrients, vitamins and minerals to assess the nutrient intakes. Also plasma mineral levels (Ca, P, Mg, Na, K, Fe, Cu, Zn) was measured. The participants were 105 middle-aged women (pre=51, Postmenopausal=54). The anthropometric measurement showed that 74% of subjects was overweight and obesity. The energy intakes were 83% of Korean EER. The macromineral intake (Ca, P, Mg, Na, K), Ca, P and Mg were 65%, > 116% and > 107% of Korean RI. Na and K intakes were > 243% and 53% of Korean AI. For the trace mineral intake (Fe, Cu, Zn), Fe, Cu and Zn intakes were 82%, > 146%, and 94% of Korean RI. The serum mineral concentration measurement, in case of Ca, Fe and Zn, > 10% of subjects showed lower level than normal clinical range. The most frequently appeared climacteric symptoms were dry eye, forgetfulness, difficult concentration, shoulder pain, fatique, depression & lonesomeness, backache, snore, dry skin, ankle & knee pain. In relation to mineral nutrition with climacteric symptoms, significant correlations have been founded between Ca intake and difficult concentration, Mg intake and snore, Fe & Zn intake and forgetfulness & dry skin, serum Ca concentration and forgetfulness, serum Na concentration and dry eyes & snore, serum K concentration and shoulder pain. From these results, it has been indicated that some mineral nutrition status may effect the prevention and reduction of climacteric symptoms in pre and postmenopause women.

Purpose: The purpose of this research was to see how wearing either a SCL or a C-SCL effected the dryness of a person's eye depending on how long they wear either type of lens. Methods: This study was carried out on 52 subjects (104 eyes) who were all in their twenties and had previously experienced wearing contact lenses. All of these subjects were required to wear either a SCL or a C-SCL, which were made out of the same material, for three months. Contents such as the McMonnies Questionnaire survey, the blinking rate per min. and the Noninvasive tear break-up time test (NIBUT) were later conducted on the subjects for this study. Results: According to the results of the McMonnies Questionnaire, it was concluded that the longer the subject wore the SCL and C-SCL, the value of the measurements gradually increased. On the other hand, the results from the NIBUT concluded that the longer the subject wore the SCL, the value of the measurements eventually decreased. However, according to the measurements of the blink rate test, it was concluded that neither results had a significant change. Conclusions: It was concluded that long-term wearing of SCL and C-SCL could be the cause of the induction and progression of dry eyes.

This study was carried out in the peatland for estimating the paleoenvironment based on the analysis from its fossils plant and radiocarbon at the Hwayang-ri, Hyeondeok-myeon, Pyeongtaek-city, South Korea. Variety of fossil was collected from the peatland which could discriminated with naked eye and sorted into seeds, leaves, stems from four-stage of standard sieve. During analysis for the large plant fossil within the peatland, the dead plants were largely divided into 3 fossil zones according to its peatland. In the fossil zone III (the oldest layer; 6,970~6,070 yr $C^{14}$ B.P.), the observation of leaves of hydrophyte such as Trapa sp. and stems of Alnus japonica which appeared in wetland means that the environment was influenced by the climate changes such as rainfall increasing and sea level rise. In the fossil zone II (the middle layer; 6,070~5,800 yr C14 B.P.), the occurrence of Gramineae, Cyperaceae and Fagaceae indicate that the environmental condition might be more or less dry by decreasing rainfall and drop in sea level. The fossil zone I (the recent layer; 5,800~4,540 yr $C^{14}$ B.P.) where lots of herbaceous plants, increasing of Fagaceae, decreasing of A. japonica. and distribution of Pinaceae were showed, was inferred to be repeated both dry and wet environment due to human disturbance.

Objectives : The purpose of the study is to examine the effect of the indoor environmental factors of dental hygienists on physical symptoms. Methods : The subjects were 210 dental hygienists in dental hospitals and clinics in Seoul, Gyeonggi Province, Incheon and South Chungnam Province from May 1 to June 20, 2013. Results : There were significant differences between the presence or absence of windows in respiratory symptoms and eye symptoms. Room temperature, bad smell, and dry humidity had significant influences on physical and respiratory symptoms. Dermatological and ophthalmological symptoms were affected by dryness, smell and dusts. Dusts and bad smell also had influences on a variety of subjective symptoms. Conclusions : The indoor environments of dental hospitals and clinics affect the respiratory, dermatological, and ophthalmological symptoms because various hazardous materials are generated by the dental treatment. Therefore dental hygienists should have a correct understanding of bacteria, dusts and bio-aerosol in order to ensure the successful environmental control.

Early-frost damages easily take place in smaller and thinner walls and slabs. In case of slabs, it is difficult to visually determine the depth of early-frost damage. As such, the current study aims to determine the depth of early-frost damage caused to concrete structures due to bad curing in the winter. As a result, the study found that the depth of early-frost damages increased from the top as the atmospheric temperature on the concrete surface decreased. The changes in the color allowed the observer to easily identify the depth of early-frost damage with the naked eye. In particular, the color difference between potentially damaged parts and undamaged parts were the greatest around thirty minutes of drying after wetting.
