Purpose: This study was designed to investigate the condition of refractive correction on wearing glasses currently of elementary school children and their accommodative ability in Jinju city. Methods: Objective refraction, subjective refraction, amplitude of accommodation, negative and positive accommodation, accommodative facility, and dynamic retinoscopy were examined on 60 elemenary school children who aged 8~12 wearing myopiacorrected glasses. Results: The condition of refractive corrections was distributed that a case of full correction was 11.7%, a case of low correction with more than 0.8 visual acuity (VA) was 10%, and a case of low correction with less than 0.8 VA was 78.3% in wearing glasses currently. In results from examination of accommodative ability, the number of children having accommodative anomaly is 8 persons (13.3%), they were divided into accommodation insufficiency (4 persons), accommodative facility insufficiency (2 persons), accommodation excess (1 person), and accommodation insufficiency related to ocular function (1 person). Conclusions: It is demanded a periodic inspection of refractive correction to growing children, and the refractive correction after due consideration to accommodative ability is really needed.

Eye examination was performed for diagnosis accommodative and binocular dysfunction. The prevalence rates were similar to other studies, therefore patients required not just the correction of the refractive error but a specific treatment for each diagnosed problems. Two symptomatic(diplopia, asthenopia, and intermittent blur) patients diagnosed as a convergence insufficiency was given full correction with visual training for 4weeks. They had a one or mixed binocular problems included accommodative insufficiency. Following 4 weeks later, visual training was effective to Improve convergence and suggest that continuous observation is necessary.

지구상에서 일어나고 있는 기후변화와 식량부족 문제에 대응하기 위한 방법으로 디지털농업화는 선진국을 중심으로 빠르게 전환되고 있다. 농촌에서의 노령화에 따른 노동력부족은 스마트팜을 비롯한 디지털농업화를 더욱 요구하고 있는 실정이고 농업이 지속 가능한 산업으로 자리잡기 위해서는 많은 변화와 정책적지원이 필요한 시점이다. 본 연구에서는 디진털농업화에 따른 농업경영체의 기업성과 결정요인에 관한 연구를 정부지원정책 프로그램 활용의 조절효과 중심으로 진행하였다. 따라서 본 연구에서는 농업경영체의 디지털기술혁신지향성, 운용혁신지향성, 생태계건강지향성, 기업가정신지향성이 기업성과에 영향을 미칠 것이라는 인과적 경로를 검증하고자 한다. 불확실한 환경 하에서 정부의 프로그램 중에서 재정적지원과 기술개발지원의 조절효과를 살펴보고 기업성과를 종속변수로 설정하여 본 연구를 진행하였다.

양식장에서 사육수의 염분변화는 어체의 삼투압변화를유도함으로써, 어류는 항상성을 유지하기 위하여 삼투압조절 즉, 수분과 세포내 염류 및 영양물질의 농도를 조절하려고 한다. 최근에는 해산어류의 삼투압 조절기능을 응용하여 담수순화 양식을 시도하려는 연구가 숭어에서 수행된 바 있으나(장과 허, 1999; 허와 장, 1999), 이외의 해산어류에 관한 삼투압조절 기능을 연구한 결과는 부족한 실정이다. (중략)

최근 발표된 고대구로병원 최경묵 교수의 연구에 따르면 당뇨병환자의 근육감소증 발병률이 일반인에 비해 3배나 높은 것으로 나타났다. 실제 근육이 많으면 당 조절에도 효과적인 것으로 알려져 있다. 당뇨병에서 걷기나 달리기 등 유산소운동의 중요성에 대해서 많이 알려져 있고, 실제 대부분의 환자들이 실천하고 있지만, 근력운동은 소홀한 경우가 많다.

The study examined the mediating effect of emotional dysregulation on the relationship between care worker's job stress and mental health. The Geriatric Caregiver's Job Stress Questionnaire, Difficulties in Emotion Regulation Scale, and The Symptom Check-List-90-R were administered to 154 care workers. Through the hierarchical regression analysis, direct interrelationship among job stress, emotional dysregulation, and mental health was examined. Furthermore, the statistical significance of mediating effect of emotional dysregulation on the relationship between job stress and mental health was tested through the bootstrapping. The result showed that the lack of emotional clarity and the limited access to emotion regulation strategies appeared to have a complete mediation effect on the relationship between job stress and mental health. That meant the necessity of adaptive emotional regulation in dealing with mental health problem elicited by job stress.

원예작물의 개화는 일장이나 생장조절제 처리 이외에도 광도, 관수량, 그리고 시비수준 등 재배환경에 따라 영향을 받는다. 차광처리는 광합성률을 낮추어 개화를 지연시키며, 관수처리는 건조시 양분흡수가 저해되거나, 수분부족 자체가 스트레스로 작용하여 종자생산을 촉진시키는 생식생장으로의 전환을 유도할 가능성도 있다. 쑥갓은 국내에서 엽채류로 4계절을 통해 많이 이용되나 개화생리에 대한 연구가 미비하다. (중략)

식물은 생육에 필요한 특정양분의 요구도가 환경요인, 품종 및 생육단계에 따라 좌우된다. 양액내 특정양분의 부족과 축적은 NFT같은 순환식 재배시스템에서 많은 문제점으로 나타나고 있는데 이는 식물생육이 주로 근권내 EC 조절에 의존하기 때문이다. 일반적으로 Ca, Mg, SO$_4$, Cl, Na, HCO$_3$$^{-}$등이 축적되기 쉬워 대규모 엽채류 재배농가와 식물공장에서 작물생육에 영향을 주는 것으로 알려져 있다. (중략)

환경수의 변화중 염분변화는 어체의 삼투압의 변화를 유도하고, 이때 어류는 염분 변화에 대처하기 위하여, 항상성(homeostasis) 유지측면의 삼투압 조절을 한다. 이러한 환경수의 염분변화에 따라 어류는 일정한 체내 삼투압 유지를 위하여 수분과 세포 내 염류 및 영양물질의 농도를 조절하려고 한다. 해산어류의 삼투압 조절기능을 응용하여 담수순화에 관한 연구보고는 숭어에서 수행되어 왔으나(장과 허, 1999; 허와 장, 1999), 다른 어류에 관한 자료는 부족한 실정이다. (중략)

The aim of this work was to study the relationship between subjective symptoms and binocular function during near work in forty one(12-17yr) schoolchildren. CISS symptom survey, amplitude of accommodation, accommodative facility, neagative relative accommodation(NRA)/positive relative accommodation(PRA) near point of convergence(NPC), heterophoria, AC/A ratios were measured. The results of measurement were compared with normal expected value of each test and classified into normal and abnormal group. Accommodative insufficiency was more general than convergence insufficiency and esophoria was greater than exophoria. NRA/PRA showed very high and AC/A ratios were very low compare with normal expected value. The results of CISS was as follows; most frequent symptom was tired, mean score was $16.63{\pm}7.49$, mean number of symptoms were $10.07{\pm}3.04$, and mean number of serious symptoms were $1.98{\pm}2.13$. After classified into 4 groups according to score of symptoms, number of symptoms, and degree of symptoms and then analyze the correlation compare with binocular vision test results. NRA was most correlated with group comparison, accommodative facility was most correlated with score of symptoms, NRA was most correlated with number of symptoms, and near horizontal phorias were most correlated with serious symptoms. NRA showed most correlative relation with near symptoms.
