This research aims to grasp the use status and satisfaction level based on citizen consciousness in night time to improve future design. This study employs a combination literature review and field survey. In the literature review, the related materials were collected to obtain the most useful information for references, and the POE study of the Bomunsan Park was conducted. The survey instrument is a questionnaire that includes questions regarding Bomunsan Park. Data were analyzed using the Statistical Package for the Social Sciences(SPSS17.0 for Windows). Through the POE analysis of the usage status and variables which significantly affect the users’ degree of satisfaction with the spaces and facilities were investigated and the following problems have been found. Bomunsan Park requires extensive modification to meet the demand of citizens. Several shortcomings are hampering the development of the Park. The rest space and the nightscape seem to be the two most problematic aspects in the Park. The nightscape design should be particularly emphasized in the overall park design in the future. Usage night and space and facilities for user satisfaction analysis, the increase of bus routes and the lighting was the biggest problem. Therefore, future access to transportation means and at night design considerations will be based on the need to plan.

차이기반회귀모형을 이용한 이상치 판별

박천건(Chun Gun Park) 한국데이터정보과학회 2018 한국데이터정보과학회지 Vol.29 No.2

다중선형회귀모형에서 이상치는 통계적 추론에 상당한 악영향을 준다. 지금까지 이상치가 회귀분석에 미치는 영향을 회피하고자 다양한 이상치 탐색 기법들이 연구되어 왔다. 이러한 노력에도 불구하고 모형선택과 이상치가 복합적 문제로 발생되면 회귀분석에 상당한 어려움을 주게 된다. 본 연구는 차이기반회귀모형을 소개하고 모형선택에 어느 정도 자유로운 이상치 탐색 알고리즘을 소개한다(Park과 Kim, 2017). 또한 Park과 Kim (2017)이 제시한 이상치 탐색 알고리즘은 “회귀모형에 이상치가 항상 존재해야 한다는 가정”이 있다. 이러한 가정의 약점을 극복하고자 본 연구는 단일 변수에서 강건하게 이상치를 탐색할 수 있는 방법을 기존 알고리즘에 추가하고 모의실험 결과를 제시한다. In a multiple linear regression model, outliers have a significant adverse effect on statistical inference. So far, various outlier detection techniques have been studied in order to avoid the effects of abnormal values on regression analysis. In spite of these efforts, if the model selection and the anomaly occur as a complex problem, the regression analysis becomes difficult. This study introduces the difference based regression model and the somewhat free outlier search algorithm for model selection (Park and Kim, 2017). In addition, Park and Kim (2017) proposed the algorithm for outlier detection in regression that is under “assumption that outliers always exist in the model”. To overcome the weakness of the assumption, this study adds the robust method of outlier detection for single variable to the algorithm and propose simulation studies.

This work aimed to analyze current status of by-products generation and industrial symbiosis network in Gyeongsangbuk-do, South Korea. Manufacturing sector of the province mainly consists of electronics, machinery, steel, metal-working industries. Gumi and Pohang have the 1st and 2nd largest worker population in the manufacturing sector. 21,950.7 ton/d of waste is generated from the industries in 2011, of which 82.2% is recycled. The industrial waste, which is not recycled, is mainly composed of sludge cake from domestic wastewater treatment plants, waste plastic, incinerator ash, and slag. Pohang is the largest generating city of both total and the non-recycled industrial waste in the province, and most of the waste is from Pohang steel industrial park. Symbiosis map in Pohang steel industrial park shows that most of the current material symbiosis in the industrial park is for waste refractories and slag.

Park,Eun Ok,Shin,Gun Hoon 한국무역상무학회 2012 貿易商務硏究 Vol.56 No.-

China draws lots of attention from many multinational corporations all over the world as one of the biggest market in the world. Due to the huge territory and explosive population, it is considered that China has endless potentiality. Moreover, since China joined the WTO, China opens its market, developing the policies for opening of its market. Based on the enormous purchasing power, China gets another attention in industry of electronic commerce. With the development and expansion of information technologies, China's electronic commerce has rapidly developed. Since the market of electronic commerce in China is in the developing stage, there is still a big market for electronic commerce and also Chinese government has made much effort in order to develop the industry of electronic commerce. However, in spite of these circumstances, the Chinese electronic commerce industry is far behind the developed countries. There could be many reasons for slow development in industry of electronic commerce and the main purpose of this paper is to discuss these reasons. First of all, the current status of electronic commerce industry in China will be analysed, and then, main problems of electronic commerce industry will be discussed in order to find out the reasons why the industry of electronic commerce cannot develop as much as it is anticipated. It is expected that this paper can contribute to understanding electronic commerce industry in China, and it will be helpful for companies which have a plan to extend their businesses in China.

Purpose : To shorten processing time for variety of medical affairs of the patient at the outpatient clinic of a big hospital is very important to qualify medical care of the patient. Therefore, patient's waiting time for drug delivery after doctor's prescription is often utilized as a strong tool to evaluate patient satisfaction with a medical care provided. We performed this study to investigate factors influencing patient satisfaction related with waiting time for drug delivery. Methods : The data were collected from July 21 to August 12, 1998. A total 535 patients or their families who visited outpatient clinics of Inha University Hospital were subjected to evaluate the drug delivery time and the level of their satisfaction related, which were compared with those objectively evaluated by Quality Improvement Team. The reliability of the scale was tested with Cronbach's alpha, and the data were analyzed using frequency, t-test, ANOVA, correlation analysis and multiple regression. Results : The mean drug delivery time subjectively evaluated by the patient (16.1 13.0 min) was longer than that objectively evaluated (10.9 7.6 min) by 5.2 min. Drug delivery time objectively evaluated was influenced by the prescription contents, total amount or type of drug dispensed, etc, as expected. The time discrepancy between two evaluations was influenced by several causative factors. One of those proved to be a patient's late response to the information from the pharmacy which the drug is ready to deliver. Interestingly, this discrepancy was found to be more prominent especially when waiting place for drug delivery was not less crowded. Other factors, pharmaceutical counseling at the pharmacy, emotional status or behavior of a patient while he waits for the medicine, were also found to influence the time subjectively evaluated. Regarding the degree of patient satisfaction with the drug delivery, majority of patients accepted drug delivery time with less than 10 min. It was also found to be influenced by emotional status of the patient as well as kindness or activity of pharmaceutical counselor. Conclusion : The results show that, besides prescription contents, behavior pattern or emotional status of a patient, environment of the waiting place, and quality of pharmaceutical counseling at the pharmacy, may influence the patient's subjective evaluation of waiting time for drug delivery and his satisfaction related with the service in the big hospital. In order to improve patient satisfaction related with waiting time for drug delivery, it will be cost effective to qualify pharmaceutical counseling and information system at the drug delivery site or waiting place rather than to shorten the real processing time within the pharmacy.

The purpose of this study was to investigate the relationships among trunk muscle, knee, and ankle strengths using Cybex770, the isokinetic muscle functioning measurement device. 41 K and Y University soccer players who did not have any experience about back pain or spine surgery were recruited as subjects. The results of the study were as follows. 1. Trunk extension was significantly higher than trunk flexion and muscle strength was diminished with increasing load speed. 2. Trunk flexion/extension ratio was well balanced at 30。/sec but this balance was broken with increasing load speed. 3. At 60。/sec of load speed, the knee extension and flexion of the left side were higher than those of the right side. 4. At 60。/sec of load speed, the ipsilateral muscle strengths of the left knee were well balanced but those of the right side were imbalanced. 5. At 60。/sec of load spped, the ratio of bilateral muscle strength of knee was -18.5±32.3% and this implies the possibility of knee injury. 6. Plantalflexion and dorsiflexion of the right ankle were higher than those of the left side, and dorsiflexion/plantalflexion ratio of the left side was higher than that of the right side. 7. The ratio of bilateral muscle strength of ankle at 60。/sec of load speed represented a balanced muscle development but this balance was broken with increasing load speed.8. There were partially significant relationships between trunk muscle and knee strengths. and between knee and ankle strengths. In conclusion, the trunk muscle strength of soccer player might be a very important factor to improve performance. In addition. a training technique which considering strength and speed is needed to develop not static but dynamic strength. This training not only develops well balanced muscle strength but also protects sport injury. Thus, the isokinetic training of trunk could improve the trunk muscle strength. and increase the ability of flexion/extension of knee and ankle.

漢語的把字句是個擺獨特的句子結構形式, 世界各地學者崙嘗S興趣,發表了許多文章, 仍是在敎學和語法硏究上老大難的問題. 關于把字句的語義語用問題薛鳳生(1989)和崔希亮(1995)的兩篇文章都有覩精彩的論述,薛鳳生說껄鑑字句 中的VP必須是一個說明 由于某一行動而造成B的某一狀態的描述語段, 崔希亮對此起些反論, 把害修改補充 :從句法結構形式上看, 把字句分成兩大類型, 典型形式和其他形式 讀兩個頻型從語義上看,可以分成結果類和情態矢量類. 本文對雌有徵大啓發, 一步走向深入, 再考察一下那個'其池形式'的語義結構和使用頻率能否獲得確證, 本文得到的結論和他們大致相同. VP必須說明由于某一行動而造成NP(把字的賓語)的某一狀態的'典型把字句'占90%以上, 而本文的『類型占5%以下. 在語義結構上, 這『類型脚然不是顯性但是隱性地說明 由于VP的行動而造成NP(把字的賓語)的某一狀態的捕述, 其功用在于隱性說明B在某一行動的作用下所發生的變化或將要發生的變化.
