근간 여름철 장마와 원료보관의 실수로 단미사료나 완제품사료의 부패변질로 급성 또는 눈에 보이지 않은 만성적인 중독증상으로 피해를 보는 예가 일어나고 있으며, 또 사실 관리상의 문제점으로 일어나는 각종 생산성 저하가 곰팡이 피해로 잘못 생각되는 경우가 있다. 이의 확실한 이론을 익혀 사양가의 사양관리에 도움이 되었으면 한다.

Perchloromethyl mercaptan에 대한 직업적 노출기준으로 TLV-TWA 0.1 ppm(0.76 mg/$m^3$)으로 권고한다. TLV-TWA 0.1 ppm(0.76 mg/$m^3$) 은 눈과 코의 자극 그리고 불쾌한 냄새로 인한 불편함의 가능성을 최소화하는 수준이다. Perchloromethyl mercaptan에 대한 동물 노출 실험연구와 근로자들의 노출연구 자료는 매우 제한적이다. 사고로 확인되지 않은 농도에 근로자들이 노출된 경우, 발견된 증상과 징후는 눈, 목, 가슴에 심한 자극과 기침, 눈물, 호흡곤란, 메스꺼움, 구토, 빈맥, 청색증, 경련 그리고 폐부종에 의한 사망이다. Perchloromethyl mercaptan을 활용하는 생산설비에서 TLV-TWA 0.1 ppm 이하 농도의 증기에 노출되었을 때 질병을 유발하였다는 보고는 없었다. 피부흡수, 발암성 그리고 TLV-STEL을 권고하기 위한 유용한 자료는 충분하지 않다.

2007년 한국인의 평균 수명은 78.5세(여성 82세, 남성 75세)로 나타났다. 의학의 발달은 세계적으로 노인인구를 증가시키고 있고 이미 우리나라도 유엔이 분류한 고령화 사회로 진입했다. 단순히 얼마나 오래 살았느냐를 나타내는 지표인 '평균수명'보다 건강하게 얼마나 살았느냐를 나타내는 지표인 '건강수명'이 더 중시되는 시대가 된 것이다. 건강수명 중에서도 '눈의 건강'은 젊게 사는 인생의 중요한 잣대이며 이에 따라 나이가 들면서 생기는 증상 중 하나인 노안에 대한 관심도 높아지게 됐다. 여기서 한 가지 주목할 점은 평균수명이 늘어나도 노안이 찾아 오는 시기는 45세에서 오히려 내려가고 있다는 점이다. 대개 45세 전후가 보편적이나 이전에 비해 30대 후반에 노안이 찾아오는 경우가 늘어나고 있는 것이 현실이다. 노안은 가까운 거리의 물체가 잘 보이지 않는 증상으로 노인들에게 흔히 나타나는 증상 중 하나였으나 최근엔 30대 후반에도 빈번하게 나타나고 있으니 적절한 관리와 주의가 요망된다. 그렇다면 노안의 증상과 치료방법에는 어떠한 것들이 있는지 알아보자.

Purpose: The purpose of this study is to evaluate the long-term stability of the improved symptoms and accommodative functions after completion of accommodative therapy. Methods: Seven children (mean age${\pm}$SD: $12{\pm}1.41$ years) who were successfully treated with a vision therapy program for either accommodative insufficiency or infacility were followed for 1 year. The visual symptoms of the subjects were measured by the College of Optometrists in Vision Development Quality of Life (COVD-QOL) checklist, and this was followed by measurement of the monocular and binocular accommodative facility with ${\pm}2.00$ D flipper lens. Results: The mean visual symptoms at the 1 year follow-up examination ($15.14{\pm}8.59$) showed a small increase, but there was no significant difference (p=0.446) from post-therapy ($11.86{\pm}7.22$). There was small regression in the monocular (left eye, $13.86{\pm}3.93cpm$) and binocular ($11.14{\pm}3.13cpm$) accommodative facility at the 1 year follow-up examination, but there were no significant different from the monocular ($15.86{\pm}4.14cpm$, p=0.147) and binocular ($13.21{\pm}3.76cpm$, p=0.066) accommodative facility measurements at post-therapy. Also, every subject met the normative values of ${\geq}7$ cpm for monocular accommodative facility and ${\geq}5$ cpm for binocular accommodative facility in the long-term. Conclusions: There was long-term maintenance of the improved visual symptoms and accommodative functions, and so it is clear that the positive therapeutic effects persist with accommodative therapy.

The study aimed to examine the state of visual acuity tests in preschoolers and determine the factors affecting the deterioration of their vision. A total of 172 pair, child aged 5-7 years and either one of their parents, were recruited from childcare centers or kindergarten between August 2015 and January 2016. Questionnaires were administered to the parents, and the children's visual acuities were measured. Using forward selection in logistics regression analysis, factors affecting vision deterioration were elucidated. Of 172 children, 128 (74.4%) had undergone a visual acuity test previously and 77 (44.8%) showed a deterioration in their vision. Children who had undergone their first visual acuity test after the age of 7 years (OR=7.425, CI=2.844- 19.385) and showed more abnormal eye symptoms, such as squinting or tilting the head to see or falling down frequently (OR=3.084, CI=1.202-7.914) and whose age was younger (OR=10.335, CI=3.252-32.848), were more likely to develop deterioration of vision. Children who had a posture such that they looked up at the computer monitor from below (OR=.075, CI=.022-.255), were less likely to show deterioration of vision. It can be inferred that early visual acuity tests is essential to detect deteriorated vision of preschoolers. Therefore, it is necessary to educate parents, personnels in day care center, and health clinics about the importance of early visual acuity tests and close observation of specific behaviors related to vision deterioration. Development of precautionary intervention program of vision deterioration in preschoolers and examination of its effects are needed.

본 연구는 서울지역 초등학교 학생 4, 5, 6학년 남 ${\cdot}$ 녀 초등학생들을 대상으로 봄철 대기오염농도와 일별 자각증상 과의 관련성에 대한 패널연구를 수행하였다. 로지회귀분석방법 중 일반화 추정 방정식(generalized estimating equations:GEE)모델을 이용하여 통계분석을 실시한 결과로는 서울지역 초등학교 학생들은 호흡기 증상보다는 피부가려움이나 눈의 따가움 등의 자극증상에 호흡성먼지(PM10)와 아황산가스 그리고 이산화질소 등의 대기오염물질 농도와 관련성이 있는 것으로 추정되었다.

A cross-sectional study was conducted to evaluate the relationship between sick building syndrome(SBS) and the environmental factors affecting SBS on 130 underground workers and 60 controls. The study consisted of 1) a review of environmental condition 2) measurement of temperature, $O_2$, $CO_2$, CO, and formaldehyde and 3) a questionnaire survey of symptom prevalence and perception of environmental conditions using indoor Air Quality questionnaire recommended by National Institute for Occupational Safety and Health. Bronchitis and dust allergy were more prevalent in underground workers significantly(p < 0.05). Among the 18 symptoms related to the indoor air pollution, the experience rate of dry, itching or irritated eyes, sore or dry throat, chest tightness, tired or strained eyes and dry or itchy skin symptom was significantly different between the underground workers and controls. The diagnostic criteria of SBS was defined as at least 1 symptom is experienced 1-3 times a week during the last 1 month among 18 indoor air pollution related symptoms which can be relieved by moving out of the underground. Applying the criteria, the mean symptom score was significant higher in underground workers than controls significantly (p < 0.05). These resalts indicated that underground workers are under inappropriate ergonomic and physical condition and inadequate ventilation. Their experience rate of symptoms related to indoor air pollution and prevalence of SBS was significantly higher than controls. To reduce the prevalence of SBS of underground workers, the surveillance system of indoor air quality, restriction of using fuel in underground and legislative regulations for the environment are needed to establish a better indoor air quality. Early detection, treatment and prevention of SBS through medical attention is also needed.

To characterize the recent outbreaks of canine distemper (CD) in Korea, we carried out epidemiological investigations by clinical observations, serum neutralizing (SN) antibody titer determination and RT-PCR on the 315 dogs which were clinically suspected as canine distemper virus (CDV) infection. One hundred and sixty two of 315 dogs were infected with CDV. Breed or gender did not seem to have effects on the prevalence of CD. The major part of dogs were in young age from 6 weeks to 18 weeks of age, and were not vaccinated or incompletely vaccinated. Clinical signs of dogs with CD were multi systemic and extremely variable. Dogs died from CD had significantly more ocular signs and neurologic signs than those of dogs survived (p<0.05). The SN titers against CDV of 157 (96.9%) dogs were under 1:16, which is less than protective level. One possible explanation for recent outbreaks of CD in Korea might be low antibody titers against CDV because of vaccination failure. Therefore, to reduce the impact of virulent infection in the dog population, dogs should be vaccinated adequately and prophylactic measures should include isolation of young dogs from the dog population until vaccination can be expected to provide protection.

당뇨는 우리 몸 구석구석에 영향을 주어 다양한 증상을 불러일으킨다. 당뇨병이 눈, 혈관, 신장 등에 영향을 준다는 것은 다들 아는 사실이나 이비인후과적 합병증은 다소 생소할 수 있다. 하지만 당뇨병이 난청, 악성 외이도염, 수면무호흡증 등을 발병시킬 수도 있다. 당뇨관리의 부주의가 어떤 이비인후과적 질환을 가져오는지 알아보자.
