하수처리장 운전 제어 및 자동화는 현재 세계적인 추세이다. 자동 제어를 도입함으로써 운전의 효율성 및 안정성 향상, 일관된 운전, 운전비용 절감 등 많은 이득을 기대할 수 있다. 유럽 등 선진국에서는 이미 7,80년대부터 다방면에서 많은 역구가 수행되었고, 80년대 이후 건설된 대부분의 하수처리장에서 용존산소 농도 제어를 비롯한 기본적인 제어를 실제로 적용하고 있다. 그러나 현재까지 국내에는 하수처리장에 자동 제어가 적용된 경우가 없으며, 현장 적용은 몇몇 폐수처리장에 국한된다. 그러나 자동 제어를 통해 얻을 수 있는 이득이 매우 크다는 것이 명백하고, 현재 각 대학 연구에서 활발하게 연구를 수행하고 있으므로, 가까운 장래에 많은 하·폐수처리장에 자동 제어가 광범위하게 도입될 것으로 기대된다. Operational control and automation of sewage works is a worldwide tendency. By introducing automatic control, many benefits like improvement of efficiency and stability, consistent operation an operational cost saving, can be obtained. Lots of process studies have been performed from 7,80s in developed countries, and basic control (e. g. DO control) is having been appplied to almost every plants constructed after 80s. In Korea, no large sewage work is automatically controlled till now, while some limited application for wastewater treatment plants are exist. But it is very clear that automatic control holds great porfits and lots of vigorous researches are being conducted in many universities and laboratiories, so widespread introduction of automatic control to sewage/wastewater treatment plant in near future is expected.

Measuring Consumers` Value of Organic-Beef using Contingent valuation method

( Joo Nyung Heo ),( Myung Hwan Sung ) 한국농촌경제연구원 2004 Journal of Rural Development Vol.27 No.2

The dichotomous-choice contingent valuation method is applied to measure consumers` value of quality-certificated organic beef. First, a logit model is estimated like previous studies. Second is a distribution-free approach. The Turnbull empirical distribution model is employed to solve negative willingness to pay and truncation problems. The result is shown that consumers are willing to pay 7,019~10,607 Won/per 600g more than the current price of regular beef for quality-certificated organic beef.

HEO, Joo-nyung,KIM, Yong-lyoul Korean Society of Rural Planning 2016 농촌계획 Vol.22 No.1

The purpose of this paper is to decide priorities of policy-objectives and support measures related to the $6^{th}$ industrialization of agriculture, and prepare policy-objectives and alternatives to contribute to maintaining and promoting the community through creation of more jobs and added value. We used the Analytic Hierarchy Process (AHP) to reflect the experts' opinions about objectives, means and priorities of the $6^{th}$ industrialization of agriculture. The important objectives of the 6th industrialization of agriculture were to create jobs, to increase added values, and to maintain and activate the community. The results showed that the most important objectives for the $6^{th}$ industrialization of agriculture were maintaining and activating the community, expanding added values and creating employment in order. Policy means to achieve these objectives were financial support, human resource training & consulting, research & development, and marketing. The decision-makers determined marketing as the most important among the policy means to achieve the objectives of the $6^{th}$ industrialization.

Invisible perforation during an endoscopic procedure of the esophagus under general anesthesia - A case report -

Heo Hyun Joo,Lee Ji Hye,Kim Yu Yil,Baek Seung Min,Kim Ki Man,Jung Da Wa 대한마취통증의학회 2020 Anesthesia and pain medicine Vol.15 No.3

Background: Endoscopic procedures of the esophagus are more complicated than those of other regions of the gastrointestinal tract. They have a relatively long procedure time and high risk of complications, such as perforation and bleeding. Perforations that occur during the procedure can accompany pneumoperitoneum and pneumomediastinum through leakage of insufflation air and cause severe ventilatory impairment.Case: A 58-year-old male patient underwent enucleation of leiomyoma in the esophagus using endoscopy under general anesthesia. Ventilatory impairment occurred 15 min after commencement of the procedure. Subsequently, subcutaneous emphysema and severe abdominal distension were observed. We suggested the possibility of microperforation during the procedure to the endoscopist, and he performed endoscopic clipping around the excision site of leiomyoma. Conclusions: Providing anesthetic care by anesthesiologists during endoscopic procedures is considered necessary for patient safety. Complications of endoscopic procedures can be detected and managed early without sequelae during anesthetic care.

치아경조직의 소실은 반드시 치아우식증이나 사고에 의해서만 일어나는 것이 아니라 마모에 의해서도 일어난다. 마모에 영향을 미치는 인자들은 시간/나이, 성별, 이갈이와 같은 과기능, 저작력, 위장관장애, 음식물, 환경적인 영향, 타액의 상태 그리고 교합적인 조건들이 있다. 한편 중심위와 최대교두감합위 불일치가 악구강계에 미치는 영향에 관해서는 아직도 논란이 분분하다. 본 연구의 목적은 중심위와 최대교두감합위의 불일치가 치아마모에 미치는 영향과 중심위에서 제일 먼저 담는 치아와 나머지 치아의 마모에 있어서 차이에 대해서 알아 보는 것이다. 본 연구는 두개하악관절과 저작습관에 이상이 없으며, 식이습관에 문제가 없으며 치아우식증과 치주질환, 수복물, 교정 또는 교합치료의 경험이 없는 21세에서 25세 사이의 서울대학교 치과대학생을 대상으로 하였다. 교합기를 이용하여 중심위 교합-최대교두교두감합위 불일치를 조사하여, 중심위 교합-최대교두감합위가 불일치가 작은 군과 큰 군으로 나누었다. 각 군은 각각 10명의 피검자들로 구성되었다. 각 피검자의 인상채득 후 CR mounting을 시행하고 중심위교합-최대감합위 불일치를 측정한 다음 임상검사로 ordinal scale을 측정하고 모형을 통해 arbitrary scale을 측정하였다. 평균치아마모도 그리고 중심위에서 먼저 닿는 치아와 나머지 치아, 나머지 구치의 마모도를 각각 조사하여 통계처리하였다. 1. 평균치아마모도는 ordinal scale로 측정하였을 매 중심위 교합-최대교두감합위 블일치가 작은 군과 큰 군 사이에 통계적으로 유의할만한 차이가 없었다(p>0.05). 2. 평균치아마모도는 arbitary scale로 측정하였을 때 중심위 교합-최대교두감합위 불일치가 작은 군과 큰 군 사이에 통계적으로 유의할만한 차이가 없었다(p>0.05). 3. CR에서 먼저 닿는 치아와 나머지 치아,나머지 구치의 마모도는 ordinal scale로 측정하였을 때 통계적으로 유의한 차이가 없었다(p>0.05). 4. CR에서 먼저 닿는 치아와 나머지 치아,나머지 구치의 마모도는 arbitrary scale로 측정하였을 때 먼저 담는 치아에서 통계적으로 유의한 높은 수준의 마모도를 보였다(p<0.05). Loss of hard tooth substance may be caused by factors other than caries and trauma, such as attrition, abrasion, erosion. There were many factors that could influence the type and rate of wear. These factors were time/age, gender, occlusal conditions, hyperfunction, bite force, gastrointestinal disturbances, nutrition, environmental factors, salivary factors, and other factors. On the other hand, a great deal of controversy exists regarding the effects of CRO-MI discrepancies. The purposes of this study were 1) to evaluate the amounts of CRO-MI discrepancies on the dental wear 2) to evaluate the difference of dental wear between initially contacted teeth in CR and the other teeth. 260 students of Seoul National University Dental College were examined. Those persons who had bad dietary, environmental, working, and parafunctional factors were excluded. Centric relation occlusion-maximum intercuspation discrepancies were estimated on an articulator. 10 depending on the amount of discrepancies students were selected in each group. Group 1 showed less than 0.5㎜ horizontl and vertical discrepancies and group 2 showed more than 1.5㎜ horizontal and vertical discrepancies. The dental wears were evaluated with ordinal scale in mouths and with arbitrary scale on dental casts. And the wear values of initially contacted teeth in CR and the other teeth, the other posterior teeth were compared. 1. The mean dental wear values in all teeth, by ordinal scale, were not significantly different between the Group 1 and Group 2 (p>0.05). 2. The mean dental wear values in all teeth, by arbitrary scale, were not significantly different between the Group 1 and Group 2 (p>0.05). 3. The dental wear values, by ordinal scale, were not significantly different between the initially contact teeth and the other teeth, the other posterior teeth (p<0.05). 4. The dental wear values, by arbitrary scale, were significantly greater in initially contacted teeth than other teeth, and other posterior teeth (p>0.05).

Heo, Yoon-Young,Heo, Seong-Joo,Chang, Myung-Woo,Park, Ji-Man The Korean Academy of Prosthodonitics 2008 대한치과보철학회지 Vol.46 No.6

STATEMENT OF PROBLEM: While patient-centered outcomes are usually not reported, these may represent major aspects of the implant success for the patient. Use of a well-designed patient survey form can be an invaluable asset to the implant practitioners. PURPOSE: The objective of this study was to investigate patient satisfaction after implant therapy by means of a questionnaire. MATERIAL AND METHODS: South Korean patients (n = 100), who visited the dental examination center of Soon Chun Hyang university hospital, were asked to fill out the satisfaction questionnaire regarding aspects of cost, comfort, esthetics, chewing, gingival health, food impaction, phonetic aspect, screw loosening, and general satisfaction. Responses to statements were given on the Likert response scale. Four experimental groups of patients were distinguished with various location ($A_1,\;A_2,\;A_3$), year ($B_1,\;B_2,\;B_3$), number of implant replacements ($C_1,\;C_2,\;C_3$), and treatment cost ($D_1,\;D_2,\;D_3$). The reliability of the response scales was measured by calculation of its internal consistency, expressed as Cronbach's ${\alpha}$. The scales were distinguished by means of factor analysis method. Possible differences in scale scores among the groups were assessed by One-way ANOVA (${\alpha}$= 0.05). RESULTS: Patients responded to most of the statements with high satisfaction. But the mean scale score of statement about cost was low. After the verification of internal consistency and factor analysis, five components, e.g. general satisfaction, comfort, chewing efficiency, esthetics, and phonetic aspect were grouped together. These components could be explained with common meaning and the first factor was named as 'general satisfaction'. Differences in patient satisfaction on the scale with esthetics were present between patients who have been wearing the implant prosthesis less than three years and those more than seven years ($B_1<B_3$). CONCLUSION: The patients were generally satisfied with the outcome of implant treatment. But the patients' major complaint was high cost and while the statistically significant difference was not shown, the satisfaction scale about food impaction and esthetics was low. So the continuing efforts to make improvements about these problems are needed for the implant practitioners.
