생수 내에는 많은 미네랄이 포함하고 있으며, 이 중 칼슘, 나트륨, 칼륨, 마그네슘, 불소는 생수통에 반드시 표기해야 할 무기물이다. 칼슘, 마그네슘, 불소와 같은 무기물은 치아형성에 관여하며, 적절하게 섭취시 치아우식증을 예방할 수 있다. 현행 먹는 샘물 수질기준에 따르면 무해무기물질인 칼슘과 마그네슘에 대한 기준치는 없으며, 유해무기물질인 불소와 같은 무기물은 2 mgF/L 이하로 규정하고 있다. 본 연구는 국내에서 판매되고 있는 생수 15종을 대상으로 칼슘, 마그네슘, 불소의 농도를 측정하였고, 생수 내 무기물 함량의 표기 여부 및 무기물 농도를 비교, 검토하여 다음과 같은 결론을 얻었다. 1. 15개의 생수 중 1개의 생수를 제외하고 모두 칼슘함량을 표기하였다. 평균 칼슘농도는 34.68±31.84 mg/L, 최대 12.891±1.85 mg/L, 최소 2.0±0.02 mg/L이었다. 2. 15개의 생수 중 2개의 생수를 제외하고 모두 마그네슘 함량을 표기하였다. 평균 마그네슘 농도는 9.22±11.06 mg/L, 최대 30.43±0.75 mg/L, 최소 0.0 mg/L이었다. 3. 15개의 생수 중 4개의 생수를 제외하고 모두 불소 함량을 표기하였다. 평균 불소 농도는 0.25±0.33 mg/L, 최대 1.13±0.04 mg/L, 최소 0.01±0.03 mg/L이었다. 모두 생수는 현행 먹는 샘물 기준치인 2 mgF/L 이하에는 만족시켰다. Drinking water has lots of minerals, especially calcium, sodium, kalium, magnesium, and fluoride must be labelled on the bottle about their contents. Minerals like calcium, magnesium, and fluoride have influence to the tooth development. Appropriately taking some minerals, dental caries can be prevented somewhat degree. There is no guide line about innoxious minerals like calcium and magnesium, however, noxious mineral like fluoride, should be contained less than 2 mgF/L according to the current drinking water standard. Hereupon, it is necessary to recognize the concentration of fluoride in drinking water, so I studied 15 samples of domestic drinking water on sale about the concentration of calcium and magnesium, fluoride. The results obtained were as follows ; 1. 14 drinking waters in 15 samples showed various Ca concentration. The average Ca concentration is 34.68±31.84 mg/L. the highest is 128.91±1.85 mg/L and the lowest is 2.0±0.02 mg/L. 2. 13 drinking waters in 15 samples indicate the Mg concentration. The average concentration is 9.22±11.06 mg/L. the highest is 30.43±0.75 mg/L and the lowest is 0.0 mg/L. 3. 11 drinking waters in 15 samples indicate the F concentration. The average concentration is 0.25±0.33 mg/L, the highest is 1.13±0.04 mg/L and the lowest is 0.01±0.03 mg/L. All samples are satisfied the current drinking water standard, 2 mg F/L.

최근 치의학의 눈부신 발전과 소득의 증가에 따른 일반인의 의식 변화로 외모에 대한 관심도가 높아지고 있다. 본 연구에서는 대학병원에 내원한 동기와 교정치료를 시작하게 된 동기,치료방법 및 치료기간을 파악하여,이를 토대로 보호자와 보다 적절한 의사소통을 위한 정보를 파악하고,보호자들의 교정치료에 대한 기대를 파악하고자 본 연구를 시행하였다. 이를 위해 전북대학교 치과병원 소아치과에 내원한 교정환자의 보호자 150명을 대상으로 조사 연구한 결과 다음과 같은 결론을 얻었다. 1. 본 병원의 소아치과를 찾게 된 이유 중 대학병원이 좋을 것 같아서가 52.1%. 친지나 아는 사람의 권유가 25%. 다른 치과병원의 소개가 16.7%로 나타났다. 2. 내원 전 예상하였던 치료기간 중 2년 이상이 37.5%. 12∼18개월이 12.5%로 나타났다. 3. 교정치료를 받으려는 이유 중 부모가 부정교합을 발견하고 걱정스러워서가 58.3%, 주위사람들의 지적이 12.5%로 나타났다. 4. 소아치과 내원 환자의 치료방법은 구강 내 고정성장치가 41.7%, 가철성장치가 29.2% 구외 장치가 2.1%를 차지했다. 5. 예약 후 치료를 위해 기다리는 시간 중 5∼10분이 39.6%, 15∼30분이 4.1%로 나타났으며,기다리는 시간은 어느 정도까지 괜찮다고 생각하는가에 대해 5∼10분이 60.4%, 15∼30분이 2.1%로 나타났다. Recently, in proportion to the remarkable development of dentistry and income increases it is growing more and more a concern about changed awareness in appearance, In this study, it had a grasp of the purpose for university hospital visiting, the motive of the commencement for orthodontic treatment and a method of the treatment as well as term. Based on these, the aim of this study is to keep more of the information between parent and doctors for mutual understanding and to grasp the characteristics for the needs of orthodontic treatment. In order to conduct researches, there has made a survey of 150 persons among orthodontic patients' parents who visit CBNU hospital, the pediatric dentistry. The study has found the results like these. 1. There was a question about the reason to visit CBNU hospital in the department of pediatric dentistry for orthodontic treatment. 52.1% of respondents, the survey found, were more likely to receive a good medical service. 25% of them were counselled from a relative or an acquaintance. 16.7% of them were recommended by another dental clinic. 2. There was a question about the expected orthodontic treatment period, when at first hospital visiting. 37.5% of the respondents answered that it was a 'more than 2 years', 12.5% of them said 'from 12 months to 18 months'. 3. There was a question about the reason to receive orthodontic treatment. 58.3% of the respondents, the survey found, answered the reason was parents' concern about the malocclusion of their children, 12.5% of them said a the orthodontic problem pointed out by entourages. 4. There was a question about the method of orthodontic treatment for patients who visit the department in pediatric dentistry. 41.7% of the respondents said that it was used as 'an intra-oral fixed appliance', 29.2% of them said 'an intra-oral removable appliance', 2.1% of them said 'an extra-oral appliance'. 5. There was a question about the waiting time for treatment after a dental appointment. 60.4% of the respondents said 'from 5 minutes to 10 minutes', 4.1% of them said 'from 15 minutes to 30 minutes'. There was a question about the extent of an acceptable waiting time. It was answered to 'from 5 minutes to 10 minutes' by 60.4% of them, 2.1% of them said 'from 15 minutes to 30 minutes'.

Black pepper (piper nigrium L.) is a spice commonly used but has a problem with microbial control, so it needs non-thermal decontamination method for product quality of dried foods. Intense pulsed light (IPL) technology is a non-thermal method for superficial decontamination of foods to inactivate pathogenic microorganisms by using high peak power and short duration pulses of a broad-spectrum (170-2600 nm) using a xenon lamp. The objective of this study was to reduce total number of bacteria in ground black pepper effectively by combined treatments of IPL and immobilized TiO2 photocatalyst. Self-designed cyclone type of pilot-scaled IPL device (> 5 kg/h) was used, which makes samples to flow cyclonically in a vacuum space longer time rather than moving vertically. Using this device alone, without TiO2 coated, 0.3-0.6 log reductions were achieved under a total energy fluence of 14.85 J/cm2 (DC voltage; 1200, 1800, and 2400 V, pulse duty; 0.5, 2.1, and 3.0 ms, treatment time; 60, 120, 180, 240, and 300 s, frequency; 2 Hz). Subsequently, TiO2-coated quartz plates with different layers between light source and samples were installed to observe the effect of photocatalyst and the efficiency of decontamination was improved slightly. However to increase the effect of the photocatalyst, several factors (TiO2 particle size, TiO2 film thickness and transparency, adhesiveness between quartz and photocatalyst, etc.) need to be concerned additionally. Nevertheless, the application of IPL treatment combined with TiO2 photocatalyst offers a potential of effective non-thermal decontamination method for dealing with powder foods in food industry.

성조숙증 아동을 위한 집단미술치료 프로그램 연구

유소영(Yu, So-yeong), 박재연(Park, Jae-yeon) 조선대학교 조형미술연구소 2012 조형미술논문집 Vol.12 No.2

성조숙이란 영양불균형 내지 외부에서 유입되는 호르몬에 의해 신체적 사춘기가 또래에 비해 일찍 시작되는 것을 가리킨다. 성조숙증으로 진단받은 아동들은 보통 약물치료를 받게 되나 친구들과 다른 빠른 변화는 아이에게 성적 수치심이나 잘못된 호기심, 정서적 위축, 낮은 자존감 형성 등의 부작용을 만들 수 있으므로 각종 변화들에 대한 정서적인 도움이 성조숙증 아동과 부모에게 필요하다. 이에 본인은 미술치료 이론을 기초로 하여 성조숙증 아동의 심리적인 안정과 자기존중감 확립에 초점을 맞추어 전인적인 발달을 돕기 위한 집단 미술치료 프로그램을 연구하였다. 이후 프로그램을 실제 치료 상황에서 운용하여보고 피드백을 통해 수정, 보완 작업을 수행하고자 한다.

황간 방언의 음운론적 고찰

유소연(Yu, So-yeon) 충남대학교 충청문화연구소 2015 충청문화연구 Vol.14 No.-

Chungcheongbuk-do Yeongdong-gun Hwanggan-myeon belongs to Chungcheongbuk -do, geographically speaking, it also is close to Gyeongsangbuk- do. This place has a mixed-lingual features of Jeollabuk-do and the Gyeongsangbuk -do. Especially, Hwanggan-myeon Nangok-ri is in active-interaction with Gyeongsangbuk-do Sangju-si, which displays the lingual aspects of Gyeongsangbuk -do as well. This paper will focus on the peculiarity of Gyeongsang-patois of Hwangganmyeon area. By categorizing and analyzing the monophthong system(/i, E, (u), ∃, (?), a, u, o/) and diphthong system(/ya, y∃, yu, yo, yE, wa, w∃, wE, ?i/) of the Gyeongsang-patois using related phoneme to specify the lingual aspect of Gyeongsangbuk-do. Patios from centeral part of Korea has more tendency of semi-vowel-drop-out than the other regions. Using High-vowel phenomenon and front-vowel phenomenon, we confirmed the phonetic-value of vowel. Round-vowel phenomenon has proven that the retro-assimilation is available. Also, elimination of ‘ㄴ’, ‘ㅎ’ consonant, similar to the ones shown in the Gyeongsang-patois has also been confirmed, showing that these two are closely related.
