1. 연구목적 동서양과 고금을 통해 많은 체질 이론들이 있었지만 그 중에서도 이제마의 사상의학은 이론과 임상이 체계적으로 연계되어 있어서 널리 사용되고 있다. 이제마는 동의수세보원의 사단론(四端論), 변증론(辨證論) 등에서 체질진단의 근거로 외형(外形), 심성(心性), 증(證)의 세 가지를 제시하였으나 세 가지 기준별 임상적 중요도에 대한 연구가 이루어진 바가 없어서 임상에서 세 가지 진단 기준을 종합적으로 활용하는데 많은 어려움이 있는 형편이다. 그러므로 향후 세 가지 체질진단 기준을 임상에 적용하여 각각의 기준이 지니는 임상적 중요도를 검증하는 연구가 필요하다고 보며, 본 논문에서는 이러한 임상적 연구에 앞서 기존의 체질진단 연구를 외형(外形)과 심성(心性), 증(證)의 세 가지로 분류, 고찰하는 기초적 연구를 하고자 한다. 2. 연구방법 <동의수세보원(東醫壽世保元)>과 사상의학회지 및 사상의학 관련 도서를 중심으로 문헌적 고찰을 하였다. 본론에서는 그간의 연구들을 세 가지로 분류하여 열거하였으며. 고찰에서는 임상적으로 활용이 가능하거나 이미 완료된 연구 위주로 논하였다. 3. 연구결과 (1) 외형(外形)에 관한 연구 경험과 직관적 관찰을 통한 기상(氣像)과 사기(詞氣)위주의 연구가 선행되었고 이를 바탕으로 체형(體形)과 용모(容貌)의 실제 계측을 통한 각 체질별 이미지 정형화 연구가 진행되고 있다. 체질진단의 정확률 제고를 위해서는 이 두 가지 방법을 균형있게 활용해야 한다. (2) 심성(心性)에 대한 연구 각종 연구나 진단의 객관화 등을 위해 자기보고식 설문조사 기법이 체질진단에 응용되고 있으며, 현재까지 개발된 설문지를 이용함에는 사상변증내용설문조사지(I)의 판별식을 이용한 결과와 QSCCll의 결과를 함께 참고하는 것이 적절하다. (3) 증(證)에 대한 연구 체질증과 체질병증에 대한 연구는 원리론적 연구와 체질별 임상증상 유형에 관한 연구, 기존의 증치의학적 병증관을 사상의학적 병증개념에 적용시켜 해석하고자 하는 연구가 진행되어 왔다. 향후 현대적인 의미의 다양한 병증을 사상의학적 관점에서 해석하고 진단하기 위한 객관화 연구가 필요하며, 또한 체질의 편차를 야기시키는 근본적 문제인 장국(臟局)의 대소(大小) 및 장리(臟理)에 대한 연구도 필요하다.

Ch'ang-Ts'al-Ts'un is a rural Village near Lung-jing City in Yen-pien Korean Autonomous Province of China. It was formed about 100 years ago by Korean Immigrants and has been developed maintaing the characteristics of traditional Korean architecture. Therefore investigating the spatial structure of this village is a meanigful work to confirm and explore one branch of Korean architecture. This study aims at analyzing the spatial structure of the village using direct data collected from the field work and indirect data from books and maps. The field work consists of on-the-site survey of the village layout, interviews of residents, observation notes and photography. Ch'ang-Ts'ai-Ts'un is located 360-370 m high above the sea level and at the side of a long valley. A river flows in the middle of the valley and relatively flat arable land exists at the both sides of the river. The location of the village related to the surrounding river and mountains suggests that the site of the village was chosen according to Feng-Shui, Chinese and Korean traditional architectural theory. The main direction of the house layouts is South-western. The village has been growing gradually until today. Therefore it is meaningful to make the village layout before Liberation(1946 A.D.) because the characteristics of Korean architecture prevailed more in that period. The area of the previous village is limited to the west side of the creek. New houses were later added to the east of the creek, forming a 'New Village'. Previously the village was composed of 3 small villages: Up, Middle and Down. Also the main access roads connecting the village with the neighboring villages were penetrating the village transversely. Presently the main access road comes to the village longitudinally from the main highway located in front of the village. The retrospective layout shows the existence of well-formed Territory, Places and Axes, thus suggesting a coherent Micro-cosmos. The boundary of imaginery territory perceived by present residents could be defined by linking conspicous outside places sorrounding the village such as Five-mountains, Front-mountain, Shin-dong village, Standing-rock, Rear-mountain and Myong-dong village. Inside the territory there are also the important places such as Bus-stop, Memorial tower of patriots, Road-maitenance building and the village itself. And inside it 5 transverse and 1 longitudinal axes exist in the form of river, roads and mountains. The perceived spatial structure of the village formed by Places, Axes and Territory is geometrical and well-balanced and suggests this village is fit for human settlement. The administrative area of the village is about 738 ha, 27 % of which is cultivated land and the rest is mountain area. Initially the village and surrounndings were covered with natural forest But the trees have been gradually cut down for building and warning houses, resulting in the present barren and artificial landscape with bare mountains and cultivated land. At present the area of the village occupied by houses is wedge-shaped, 600 m wide and 220 m deep in its maximum. The total area of the village is $122,175m^{2}$. The area and the rate of each sub-division arc as follow. 116 house-lots $91,465m^{2}$ (74.9 %) Land for public buildings and shops $2,980m^{2}$ (2.4 %) Roads $17,106m^{2}$ (14.0 %) Creek $1,356m^{2}$ (1.1 %) Vacant spaces and others $9,268m^{2}$ (7.6 %) TOTAL $122,175m^{2}$ (100.0 %) Each lot is fenced around with vertical wooden pannels 1.5-1.8 m high and each house is located to the backside of the lot. The open space of a lot is sub-divided into three areas using the same wooden fence: Front yard, Back yard and Access area. Front and back yards are generally used for crop-cultivation, the custom of which is rare in Korea. The number of lots is 116 and the average size of area is $694.7m^{2}$. Outdoor spaces in the village such as roads, vacant spaces, front yard of the cultural hall, front yard of shops and spacse around the creek are good 'behavioral settings' frequently used by residents for play, chatting, drinking and movie-watching. The road system of the village is net-shaped, having T-junctions in intersections. The road could be graded to 4 categories according to their functions: Access roads, Inner trunk roads, Connecting roads and Culs-de-sac. The total length of the road inside the village is 3,709 m and the average width is 4.6 m. The main direction of the road in the village is NNE-SSE and ESE-WNW, crossing with right angles. Conclusively, the spatial structure of Ch'ang-Ts'ai-Ts'un village consists of various components in different dimensions and these components form a coherent structure in each dimension. Therefore the village has a proper spatial structure meaningful and appropriate for human living.

서울 올림픽의 휘장을 비롯하여 우리나라를 대표하는 전통 문양 중의 하나로 삼태극이 사용되고 있다. 삼태극은 태극임에도 불구하고 정확한 철학적 규명없이 일부 종교단체나 지식인들에 의해 '천지인'이라는 삼재론으로 혹은 '천지인 조화사상'이라는 넓은 틀로 해석되고 있다. 이에 삼태극의 정확한 의미를 알아보고자 하는데 본 연구의 목적을 두었다. 조선은 건국과 더불어 유교를 통치이념으로 삼았으나, 이념의 테두리에서 비교적 자유로운 곳에서는 노장과 불교, 무속 등을 묵인하여왔다. 그리하여 태극 문양을 사용함에 있어서도 유교적 이념이 드러나야 하는 공식적인 곳에서는 이태극 문양을 사용하고, 왕릉과 같은 사적인 곳에서는 삼태극 문양을 새겨왔음을 밝혀 놓았다. 이와 같이 문양을 분리 사용한 이유를 규명해보기 위하여 태극의 변화 발전 과정을 고찰해 보았다. 동양(한 중 일)에서는 태극 문양을 우주와 관련지어 생각하는 경우가 많았다. 이 문양은 한당시대까지는 삼태극이 주로 사용되었으며, 그 의미도 "한서" "율력지" 속에서'음양덕(陰陽德)'으로 나타나 있다. 그러나 이후 중국사에서 등장한 "고태극도" 속에서는 이태극 속의 흰점으로 문양이 변화되어 나타나며, 그 의미도 '음양과 생기'로 표현된다. 그러다 유가 사상이 자리 잡은 송대 이후로는 '음양과 리'로 그 해석이 이루어지게 된다. 이 과정에서 리는 '생기'와 달리 비실체성을 나타내는 것이어서, '음양과 리'를 문양으로 표현할 때는 이태극으로 표현하게 되었음을 논해 놓았다. 결론적으로 삼태극은 '음양덕' 혹은 '음양생기', '음양무극' 등을 문양으로 나타낸 것이다. 이것은 영(靈)의 세계를 인정하는 도가와 불교의 사상 속에서 주로 발달하였으며 '기'를 본체로 하는 세계관이다.

"춘추(春秋)" 경문(經文)에서는 기월법(紀月法)으로 '춘왕정월(春王正月)'의 표현 방식을 썼으며, 동짓달을 한 해의 첫 달로 삼고 그때부터 3개월을 춘(春)이라 명명하였다. 이러한 "춘추(春秋)"왕력(王曆)에 대해 그것의 월호(月號)와 계절명을 공자가 바꾸어 기록한 것인가 그렇지 않은가에 따라, 송대(宋代) 이래로 '공자(孔子)의 개월(改月) 개시(改時)' 설(說), '공자(孔子)의 불개월(不改月) 개시(改時)' 설, '공자(孔子)의 불개월(不改月) 불개시(不改時)' 설 세 가지의 서로 다는 주장들이 있게 되었다. 첫 번째 설은 호안국(胡安國)과 채침(蔡沈)이, 두 번째 설은 정이(程?)와 주희(朱熹)가 언급한 것이다. 세 번째 설은 그 주창자가 명대(明代) 이후에 두드러지기 시작하였으며 대표적인 인물로 왕수인(王守仁)을 들 수 있다. 그들 모두 자신들 주장의 근거를 고경(古經)과 유교 전적의 기록들 속에서 찾고 있는데, 동일한 기록을 가지고 서로 다른 주장의 근거로 삼은 경우도 보인다. 공자의 이른바 '춘추필법(春秋筆法)'과 '술이불작(述而不作)'은 존왕사상(尊王思想)에서 나올 수 있었던 것이다. 그렇기 때문에, 비록 공자가 "춘추"의 저자라고 가정한다 해도, "춘추(春秋)"의 역수(曆數)에서 정말로 공자가 개월(改月)이나 개시(改時)를 감행하였을지를 의심하지 않을 수 없다. 이와 같은 공자의 "춘추" 역수 개입과 관련한 설들은, 사실상 당대(唐代)까지는 대립적으로 논의되지 않은 것이다.

Nursing of today has as one of its objectives the solving of problems related to human needs arising from the demands of a rapidly changing society. This nursing objective, I believe, can he attained by the appropriate application of scientific principles in the giving of comprehensive nursing care. Comprehensive nursing care may be defined as nursing care which meets all of the patient's needs. the needs of patients are said to fall into five broad categories: physical needs, psychological needs, environmental needs, socio-economic needs, and teaching needs. Most people who become ill have adjustment problems related to their new situation. Because patient teaching is one of the most important functions of professional nursing, the success of this teaching may be used as a gauge for evaluating comprehensive nursing care. This represents a challenge foe the future. A questionnaire consisting of 67 items was distributed to 200 professional nurses working ill direct patient care at Yonsei University Medical Center in Seoul, Korea. 160 (80,0%) nurses of the total sample returned completed questionnaires 81 (50.6%) nurses were graduates of 3 fear diploma courser 79 (49.4%) nurses were graduates of 4 year collegiate nursing schools in Korea 141 (88,1%) nurses had under 5 years of clinical experience in a medical center, while 19 (11.9%) nurses had more than 5years of clinical experience. Three hypotheses were tested: 1. “Nurses had high levels of concept and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of a statistical method, the mean average. 2. “Nurses graduating from collegiate programs and diploma school programs of nursing show differences in concepts and knowledge toward patient teaching”-This was demonstrated by a statistical method, the mean average, although the results showed little difference between the two groups. 3. “Nurses having different amounts of clinical experience showed differences in concepts and knowledge toward patient teaching”-This was demonstrated by the use of the T-test. Conclusions of this study are as follow: Before attempting the explanation, of the results, the questionnaire will he explained. The questionnaire contained 67 questions divided into 9 sections. These sections were: concept, content, time, prior preparation, method, purpose, condition, evaluation, and recommendations for patient teaching. 1. The nurse's concept of patient teaching: Most of the nurses had high levels of concepts and knowledge toward patient teaching. Though nursing service was task-centered at the turn of the century, the emphasis today is put on patient-centered nursing. But we find some of the nurses (39.4%) still are task-centered. After, patient teaching, only a few of the nurses (14.4%) checked this as “normal teaching.”It seems therefore that patient teaching is often done unconsciously. Accordingly it would he desirable to have correct concepts and knowledge of teaching taught in schools of nursing. 2. Contents of patient teaching: Most nurses (97.5%) had good information about content of patient teaching. They teach their patients during admission about their diseases, tests, treatments, and before discharge give nurses instruction about simple nursing care, personal hygiene, special diets, rest and sleep, elimination etc. 3. Time of patient teaching: Teaching can be accomplished even if there is no time set aside specifically for it. -a large part of the nurse's teaching can be done while she is giving nursing care. If she believes she has to wait for time free from other activities, she may miss many teaching opportunities. But generally proper time for patient teaching is in the midmorning or midafternoon since one and a half or two hours required. Nurses meet their patients in all stages of health: often tile patient is in a condition in which learning is impossible-pain, mental confusion, debilitation, loss of sensory perception, fear and anxiety-any of these conditions may preclude the possibility of successful teaching. 4. Prior preparation for patient teaching: The teaching aids, nurses use are charts (53.1%), periodicals (23.8%), and books (7.0%) Some of the respondents (28.1%) reported that they had had good preparation for the teaching which they were doing, others (27.5%) reported adequate preparation, and others (43.8%) reported that their preparation for teaching was inadequate. If nurses have advance preparation for normal teaching and are aware of their objectives in teaching patients, they can do effective teaching. 5. Method of patient teaching: The methods of individual patient teaching, the nurses in this study used, were conversation (55.6%) and individual discussion (19.2%) . And the methods of group patient teaching they used were demonstration (42.3%) and lecture (26.2%) They should also he prepared to use pamphlet and simple audio-visual aids for their teaching. 6. Purposes of patient teaching: The purposes of patient teaching is to help the patient recover completely, but the majority of the respondents (40.6%) don't know this. So it is necessary for them to understand correctly the purpose of patient teaching and nursing care. 7. Condition of patient teaching: The majority of respondents (75.0%) reported there were some troubles in teaching uncooperative patients. It would seem that the nurse's leaching would be improved if, in her preparation, she was given a better understanding of the patient and communication skills. The majority of respondents in the total group, felt teaching is their responsibility and they should teach their patient's family as well as the patient. The place for teaching is most often at the patient's bedside (95.6%) but the conference room (3.1%) is also used. It is important that privacy be provided in learning situations with involve personal matters. 8. Evaluation of patient teaching: The majority of respondents (76.3%,) felt leaching is a highly systematic and organized function requiring special preparation in a college or university, they have the idea that teaching is a continuous and ever-present activity of all people throughout their lives. The suggestion mentioned the most frequently for improving preparation was a course in patient teaching included in the basic nursing program. 9. Recommendations: 1) It is recommended, that in clinical nursing, patient teaching be emphasized. 2) It is recommended, that insertive education the concepts and purposes of patient teaching he renewed for all nurses. In addition to this new knowledge, methods and materials which can be applied to patient teaching should be given also. 3) It is recommended, in group patient teaching, we try to embark on team teaching.

We tried to observe the features of ancient medical practice by analysing the records related to medicine in the book, ${\ulcorner}$the Historical Records of the Three Kingdom${\lrcorner}$ of which content includes the features of medicine in mythology, plague, delivery of twins, drugs, medical system, shamanism, constitutional medicine, psychiatry, forensic medicine, deformity, a spa, medical phrase, health and welfare work, religion, death. physiological anatomy, Taoist medicine, acupuncture, the occult af of transformation and etc. Our initial concern was about where to draw line as of medical field and we defined medicine in more broad meaning. The book ${\ulcorner}$the Historical Records of the Three Kingdoms${\lrcorner}$ describes the world of mythology by way of medicine which is not clearly a conventional one. There appears records of birth of multiple offsprings 7 times in which cases are of triplets or more. Delivering multiple offsprings were rare phenomenon though such fertility was highly admired. This shows one aspect of ancient country having more population meant more power of the nation. Of those medical records conveyed in that book includes stories of childbirth such as giving birth to a son after praying, giving birth to Kim Yoo-shin after 20 months after mother's dream of conception, and a song longing for getting a laudable child. Plagues were prevalent throughout winter to spring season and one can observe various symptoms of plagues in the record. Of these epidemic diseases, cold type might have been more common than the heat one. Appearance of epidemic diseases frequently coincided with that of natural disasters that this suggests a linkage between plague and underlying doctrine on five elements' motion and six kinds of natural factors. There exists only a few names of diseases such as epidemic disease, wind disease, and syndrome characterized by dyspnea. Otherwise there appeared only afflictions that were not specified therefore it remains cluless to keep track of certain diseases of prevalence. Since this ${\ulcorner}$Historical Records of the Three Kingdoms'${\lrcorner}$ wasn't any sort of medical book, words and terms used were not technical kind and most were the ones used generally among lay people. Therefore any mechanisms of the diseases were hardly mentioned. Some of medicinal substances such as Calculus Bovis, Radix Ginseng, Gaboderma Luciderm, magnetitum were also in use in those days. 53 kinds of dietary supplies appears in the records and some of these might have been used as medicinal purpose. Records concerning dicipline of one's body includes activities such as hunting, archery, horseback riding etc. In Shilla dynasty there were positions such as professor of medicine, Naekongbong(內供奉), Kongbong's doctor(供奉醫師), Kongbong's diviner(供奉卜師). As an educational facility, medical school was built at the first year of King Hyoso's reign and it's curricula included various subjects as ${\ulcorner}$Shin Nong's Herbal classic${\lrcorner}$, ${\ulcorner}$Kabeul classic of acupuncture and moxbustion${\lrcorner}$, ${\ulcorner}$The Plain Questions of the Yellow Emperor's Classic of Internal Medicine${\lrcorner}$, ${\ulcorner}$Classic of Acupuncturer${\lrcorner}$, ${\ulcorner}$The Pulse Classic${\lrcorner}$, ${\ulcorner}$Classic of Channels and Acupuncture Points${\lrcorner}$ and ${\ulcorner}$Difficult Classic${\lrcorner}$. There were 2 medical professors who were in charge of education. To establish pharmacopoeia, 2 Shaji(舍知), 6 Sha(史), 2 Jongshaji(從舍知) were appointed. In Baekje dynasty, Department of Herb was maintained. Doing praying for the sake of health, doing phrenology also can be extended to medical arena. Those who survived over 100 years of age appear 3 times in the record, while 98 appears once. The earliest psychiatrist Nokjin differentiated symptoms to apply either therapies using acupuncture and drug or psychotherapy. There appears a case of rape, a case of burying alive with the dead, 8 cases of suicide that can characterize a prototype of forensic medicine. Deformity-related records include phrases as follow: 'there seems protrudent bone behind the head', 'a body which has two heads, two trunks, four arms.', 'a body equipped with two heads' In those times spa can be said to be used as a place for he리ing, convalescence, and relaxation seeing the records describing a person pretended illness and went to spa to enjoy with his friends. Priest doctors and millitary surgeons were in charge of the medical sevice in the period of the Three Kingdoms by the record written by Mookhoja(墨胡子) and Hoonkyeom(訓謙). Poor diet and regimen makes people more vulnerable to diseases. So there existed charity services for those poor people who couldn't live with one's own capacity such as single parents, orphans, the aged people no one to take care and those who are ill. The cause of affliction was frequently coined with human relation. There appeared the phenomenon of releasing prisoners and allowing people to become priests at the time of king's suffering. Besides, as a healing procedure, sutra-chanting was peformed. There appears 10 cases of death related records which varies from death by drowning, or by freezing, death from animals, death from war, death from wightloss and killing oneself at the moment of spouse's death and etc. There also exist certain records which suggest the knowledge of physiology and anatomy in those times. Since the taoist books such as ${\ulcorner}$Book of the Way and Its Power(老子道德經)${\lrcorner}$ were introduced in the period of Three Kingdoms, it can be considered that medicine was also influenced by taoism. Records of higher level of acupuncture, records which links the medicine and occult art of transformation existed. Although limited, we could figure out the medical state of ancient society.

대학 교육에 있어서 전공과목의 선택은 학생들의 진로에 중요한 역할을 한다. 하지만, 산업의 변화에 발맞춰 대학 교육도 학과별 전공과목의 분야가 다양해지고 그 수가 많아지고 있다. 이에 학생들은 본인의 진로에 맞게 수업을 선택하여 수강하는 것에 어려움을 겪고 있다. 본 연구는 대학 전공과목 추천 모델을 제시함으로써 개인 맞춤형 교육을 실현하고 학생들의 교육만족도를 제고하고자 한다. 모델 연구에는 대학교 학부생들의 2015년~2017년 수강 이력 데이터를 활용하였으며, 메타데이터로는 학생과 수업의 전공 명을 사용했다. 수강 이력 데이터는 컨텐츠 소비 여부만을 나타낸 암시적 피드백 데이터로, 수업에 대한 선호도를 반영한 것이 아니다. 따라서 학생과 수업의 특성을 나타내는 임베딩 벡터를 도출했을 시, 표현력이 낮다. 본 연구는 이러한 문제점에 착안하여, 네트워크 분석을 통해 학생, 수업의 벡터를 생성하고 이를 모델의 입력 값으로 활용하는 Net-NeuMF 모델을 제시한다. 모델은 암시적 피드백을 가진 데이터를 이용한 대표적인 모델인 원핫 벡터를 이용하는 NeuMF의 구조를 기반으로 하였다. 모델의 입력 벡터는 네트워크 분석을 통해 학생과 수업의 특성을 나타낼 수 있도록 생성하였다. 학생을 표현하는 벡터를 생성하기 위해, 각 학생을 노드로 설정하고 엣지는 두 학생이 같은 수업을 수강한 경우 가중치를 가지고 연결되도록 설계했다. 마찬가지로 수업을 표현하는 벡터를 생성하기 위해 각 수업을 노드로 설정하고 엣지는 공통으로 수강한 학생이 있는 경우 연결시켰다. 이에 각 노드의 특성을 수치화 하는 표현 학습방법론인 Node2Vec을 이용하였다. 모델의 평가를 위해 추천 시스템에서 주로 활용하는 지표 4가지를 사용하였고, 임베딩 차원이 모델에 미치는 영향을 분석하기 위해 3가지 다른 차원에 대한 실험을 진행하였다. 그 결과 기존 NeuMF 구조에서 원-핫 벡터를 이용하였을 때보다 차원과 관계없이 평가지표에서 좋은 성능을 보였다. 이에 본 연구는 학생(사용자)와 수업(아이템)의 네트워크를 이용해 기존 원-핫 임베딩 보다 표현력을 높였다는 점, 모델을 구성하는 각 구조의 특성에 맞도록 임베딩 벡터를 활용하였다는 점, 그리고 기존의 방법론에 비해 다양한 종류의 평가지표에서 좋은 성능을 보였다는 점을 기여점으로 가지고 있다.

本研究的目的是对咖啡店的 "重要性"（顾客在光顾咖啡店以前的感知）和积极或消极的 "满意度"（顾客在光顾咖啡店以后的感受）之间的差距进行分类, 并分析这些差距对对购买行为的影响. 为此, 我使用重要性和满意度之间的差距作为选择咖啡店的解释变量, 并通过使用有序Probit模型（OPM）来实证分析差距对购买行为（整体满意度和愿意到再次光顾）的影响方向和大小. 先前使用IPA的研究评估了差距影响的方向和大小的象限, 但是在分析差距对顾客的影响方面却失败了. 在本研究中, 我评估了积极和消极的差距对顾客满意度和愿意去再光顾的影响. 通过使用OPM,我量化了积极和消极的差距对顾客整体满意度和愿意去再光顾的影响. 每个人的支出, 光顾的频率和购买咖啡的地方对顾客整体满意度有最积极的影响. 光顾的频率, 在每人的支出之后, 然后是购买咖啡的地方对顾客整体满意度有最积极的影响. 因此每个人的支出和光顾的频率对顾客整体满意度有最积极的影响. 这一发现意味着一个在咖啡店每次或每周花费5000韩元的顾客的实际的满意度越高（差距), 其整体满意度和愿意去再光顾就越高. 虽然经济效益对总体满意度和愿意去再光顾有显著影响, 但是大专和大学的学生仍然愿意去咖啡馆并愿意消费5000韩元, 因为他们不只是购买咖啡本身而且将咖啡店作为其他活动的场所, 例如工作, 和朋友见面或是放松的地方. 学院和大学的学生还可以在咖啡店通过个人电脑上网, 看电影, 学习, 因此, 咖啡馆应对顾客提供适当的设施和服务. 咖啡店品牌的积极差距对愿意去再光顾有积极的影响表明顾客满意度越高, 顾客越愿意去再光顾. 另一方面, 这一因素的消极差距意味着顾客满意度越低, 顾客再光顾的意愿也越低. 因此, 在本研究中, 与其他评估的因素相比, 品牌因素对满意度有较大的影响. 鉴于国内咖啡文化变得越来越高级, 大专院校的学生对这一趋势也很敏感, 所以学生有很多可选择的品牌. 在韩国最高级的咖啡店, 外墙是玻璃建造的并可以打开, 内部是充满异国情调的开放式厨房. 这些高级咖啡店作为标志的功能复合大专院校学生的品味. 韩国咖啡店已成为一个文化品牌. 从品牌因素来看, 为了让顾客觉得这些咖啡店是高级的, 高质量的设备和提供更好服务的措施应当建立起来. 韩国咖啡馆作为蓬勃发展的行业品牌竞争加剧的结果表明, 提供与竞争对手不同的额外服务是有必要的. 顾客可以免费使用扫描仪. 另一个可以用来提高品牌的战略是提供和经营为集体学习而准备的讨论会议室. 如果咖啡馆采取这些类型的策略, 学院/大学的学生将更有可能认为他们承担的费用是值得的, 随后, 他们将可能更满足这些咖啡馆的品牌, 并更愿意再次光顾. 性别和学习年数对总体满意度和再光顾的意愿有最消极的营销. 女学生比男学生更容易满足和再光顾. 三, 四年级的学生比一, 二年级的学生更容易满足和再光顾. 喝咖啡的学生, 单独在咖啡店看书, 用笔记本电脑是很容易被注意到的. 高年级学生为了有效地利用时间用于自我发展和寻找工作往往独自光顾咖啡店. 从积极的差距来看, 经济效率这一因素对总体满意度和愿意再光顾有最大的影响. 与咖啡价格一起, 学生实际满意度（差距）越高, 总体满意度和再光顾的意愿也越高. 有消极差距的经济效率队再光顾有消极营销的结果表明较小的消极差距可以让再光顾的意愿更高. 在持续恶化的市场环境中, 坐落在大专院校附近的咖啡店采取诸如积分或会员卡, 和信用卡 公司的战略联盟, 发展套餐菜单或季节菜单和免费咖啡服务这些战略来提高竞争力. 就消极差距而言产品功率也有消极的影响, 这表明较高的负差距会导致较低的再光顾的意愿. 因为还有更多的客户比前几十年, 在这十年里更喜欢咖啡, 新一代的客户, 即学院/大学的学生, 希望除了咖啡还有更重菜单项目. 因此, 咖啡店应当增加配菜项目, 如华夫饼, 糕, 蛋糕, 三明治和沙拉. 例如, 星巴克韩国正在努力加强卖草莓糕, 艾草香味, 南瓜产品, 并提供免费的咖啡或奶油. 总而言之, 咖啡馆应注重提高其经济效率, 品牌和产品功率, 以加强大专院校学生的满意度. 由于店铺毗邻学大专院校可享受地缘优势, 就经济效率, 品牌和产品功率而言提供不同的服务, 很可能会提高客户满意度和回访. 咖啡厅的品牌, 因此, 应不断创新和变化, 以满足顾客的愿望. 由于这项研究只是针对在首尔的大专院校的学生, 需要针对不同地区和年龄组的比较研究来概括本研究的结果和建议.

Consumers differ in the way they make a purchase. An audio mania would willingly make a bold, yet serious, decision to buy a top-of-the-line home theater system, while he is not interested in replacing his two-decade-old shabby car. On the contrary, an automobile enthusiast wouldn't mind spending forty thousand dollars to buy a new Jaguar convertible, yet cares little about his junky component system. It is product involvement that helps us explain such differences among individuals in the purchase style. Product involvement refers to the extent to which a product is perceived to be important to a consumer (Zaichkowsky, 2001). Product involvement is an important factor that strongly influences consumer's purchase decision-making process, and thus has been of prime interest to consumer behavior researchers. Furthermore, researchers found that involvement is closely related to perceived risk (Dholakia, 2001). While abundant research exists addressing how product involvement relates to overall perceived risk, little attention has been paid to the relationship between involvement and different types of perceived risk in an electronic commerce setting. Given that perceived risk can be a substantial barrier to the online purchase (Jarvenpaa, 2000), research addressing such an issue will offer useful implications on what specific types of perceived risk an online firm should focus on mitigating if it is to increase sales to a fullest potential. Meanwhile, past research has focused on such consumer responses as information search and dissemination as a consequence of involvement, neglecting other behavioral responses like online merchant selection. For one example, will a consumer seriously considering the purchase of a pricey Guzzi bag perceive a great degree of risk associated with online buying and therefore choose to buy it from a digital storefront rather than from an online marketplace to mitigate risk? Will a consumer require greater trust on the part of the online merchant when the perceived risk of online buying is rather high? We intend to find answers to these research questions through an empirical study. This paper explores the impact of enduring product involvement and perceived risks on required trust level, and further on online merchant choice. For the purpose of the research, five types or components of perceived risk are taken into consideration, including financial, performance, delivery, psychological, and social risks. A research model has been built around the constructs under consideration, and 12 hypotheses have been developed based on the research model to examine the relationships between enduring involvement and five components of perceived risk, between five components of perceived risk and required trust level, between enduring involvement and required trust level, and finally between required trust level and preference toward an e-tailer. To attain our research objectives, we conducted an empirical analysis consisting of two phases of data collection: a pilot test and main survey. The pilot test was conducted using 25 college students to ensure that the questionnaire items are clear and straightforward. Then the main survey was conducted using 295 college students at a major university for nine days between December 13, 2010 and December 21, 2010. The measures employed to test the model included eight constructs: (1) enduring involvement, (2) financial risk, (3) performance risk, (4) delivery risk, (5) psychological risk, (6) social risk, (7) required trust level, (8) preference toward an e-tailer. The statistical package, SPSS 17.0, was used to test the internal consistency among the items within the individual measures. Based on the Cronbach's ${\alpha}$ coefficients of the individual measure, the reliability of all the variables is supported. Meanwhile, the Amos 18.0 package was employed to perform a confirmatory factor analysis designed to assess the unidimensionality of the measures. The goodness of fit for the measurement model was satisfied. Unidimensionality was tested using convergent, discriminant, and nomological validity. The statistical evidences proved that the three types of validity were all satisfied. Now the structured equation modeling technique was used to analyze the individual paths along the relationships among the research constructs. The results indicated that enduring involvement has significant positive relationships with all the five components of perceived risk, while only performance risk is significantly related to trust level required by consumers for purchase. It can be inferred from the findings that product performance problems are mostly likely to occur when a merchant behaves in an opportunistic manner. Positive relationships were also found between involvement and required trust level and between required trust level and online merchant choice. Enduring involvement is concerned with the pleasure a consumer derives from a product class and/or with the desire for knowledge for the product class, and thus is likely to motivate the consumer to look for ways of mitigating perceived risk by requiring a higher level of trust on the part of the online merchant. Likewise, a consumer requiring a high level of trust on the merchant will choose a digital storefront rather than an e-marketplace, since a digital storefront is believed to be trustworthier than an e-marketplace, as it fulfills orders by itself rather than acting as an intermediary. The findings of the present research provide both academic and practical implications. The first academic implication is that enduring product involvement is a strong motivator of consumer responses, especially the selection of a merchant, in the context of electronic shopping. Secondly, academicians are advised to pay attention to the finding that an individual component or type of perceived risk can be used as an important research construct, since it would allow one to pinpoint the specific types of risk that are influenced by antecedents or that influence consequents. Meanwhile, our research provides implications useful for online merchants (both online storefronts and e-marketplaces). Merchants may develop strategies to attract consumers by managing perceived performance risk involved in purchase decisions, since it was found to have significant positive relationship with the level of trust required by a consumer on the part of the merchant. One way to manage performance risk would be to thoroughly examine the product before shipping to ensure that it has no deficiencies or flaws. Secondly, digital storefronts are advised to focus on symbolic goods (e.g., cars, cell phones, fashion outfits, and handbags) in which consumers are relatively more involved than others, whereas e- marketplaces should put their emphasis on non-symbolic goods (e.g., drinks, books, MP3 players, and bike accessories).

소셜 미디어는 모바일 어플리케이션과 웹에서 가장 많이 사용되는 미디어 중 하나이다. Nielsen사의 보고서에 따르면 소셜 네트워크 서비스와 블로그가 온라인 사용자의 주 활동 공간으로 사용되고 있으며, 미국인 중에서 온라인 활동이 왕성한 5명의 사용자중 4명은 매일 소셜 네트워크 서비스와 블로그를 방문하고 온라인 활동 시간의 23%를 소비한다고 집계하고 있다. 미국의 인터넷 사용자들은 야후, 구글, AOL 미디어 네트워크, 트위터, 링크드인 등과 같은 소셜 네트워크 서비스중 페이스북에서 가장 많은 시간을 소비한다. 최근에는 대부분의 회사들이 자신의 특정 상품에 대하여 "페이스북 페이지(Facebook Page)"를 생성하고 상품에 대한 프로모션을 진행한다. 페이스북에서 제공되는 "좋아요" 옵션은 페이스북 페이지를 통해 자신이 관심을 가지는 상품(아이템)을 표시하고 그 상품을 지지할 수 있도록 한다. 많은 영화를 제작하는 영화 제작사들도 페이스북 페이지와 "좋아요" 옵션을 이용하여 영화 프로모션과 마케팅에 이용한다. 일반적으로 다수의 스트리밍 서비스 제공업들도 영화와 TV 프로그램을 즐기며 볼 수 있는 서비스를 사용자들에게 제공한다. 이 서비스는 일반 컴퓨터와 TV 등의 단말기에서인터넷을 통해 영화와 TV 프로그램을 즉각적으로 제공할 수 있다. 스트리밍 서비스의 선두 주자인 넷플릭스는 미국, 라틴 아메리카, 영국 그리고 북유럽 국가 등에 3천만 명 이상의 스트리밍 사용자가 가입되어 있다. 또한 넥플릭스는 다양한 장르로 구성된 수백만 개의 영화와 TV 프로그램을 보유하고 있다. 하지만 수많은 콘텐츠로 인해 사용자들은 자신이 선호하는 장르에 관련된 영화와 TV 프로그램을 찾기 위해 많은 시간을 소비해야 된다. 많은 연구자들이 이러한 사용자의 불편함을 줄이기 위해 아이템에 대한 사용자가 보지 않은 아이템에 대한 선호도를 예측하고 높은 예측값을 갖는 아이템을 사용자에게 제공하기 위한 추천 시스템을 적용하였다. 협업적 여과 방법은 추천 시스템을 구축하기 위해 가장 많이 사용되는 방법이다. 협업적 여과 시스템은 사용자들이 평가한 아이템을 기반으로 각 사용자 간의 유사도를 측정하고 목적 사용자와 유사한 성향을 가진 사용자 그룹을 결정한다. 군집된 그룹은 이웃 사용자 집단으로 불리며 이를 이용하여 특정 아이템에 대한 선호도를 예측하고, 예측 값이 높은 아이템을 목적 사용자에게 추천해 준다. 협업적 여과 방법이 적용되는 분야는 서적, 음악, 영화, 뉴스 및 비디오 등 다양하지만 논문에서는 영화에 초점을 맞춘다. 이 협업적 여과 방법이 추천 시스템 내에서 유용하게 활용되고 있지만 아직 "희박성 문제"와 "콜드 스타트 문제" 등 해결해야 할 과제가 남아있다. 희박성 문제는 아이템의 수가 증가할수록 아이템에 대한 사용자의 로그 밀도가 감소하는 것이다. 즉, 전체 아이템 수에 비해 사용자가 아이템에 대해 평가한 정보가 충분하지 않기 때문에 사용자의 성향을 파악하기 어렵고, 이로 인해 사용자가 아직 평가하지 않은 아이템에 대해서 선호도를 추측하기 어려운 것을 말한다. 이 희박성 문제가 포함된 경우 적합한 이웃 사용자 집단을 형성하는데 어려움을 겪게 되고 사용자들에게 제공되는 아이템 추천의 질이 떨어지게 된다. 콜드 스타트 문제는 시스템 내에 새로 들어온 사용자 또는 아이템으로 지금까지 한 번도 평가를 하지 않은 경우에 발생한다. 즉, 사용자가 평가한 아이템에 대한 정보가 전혀 포함되어 있지 않거나 매우 적기 때문에 이러한 경우 또한 적합한 이웃 사용자 집단을 형성하는데 어려움을 겪게 되고 사용자가 평가하지 않은 아이템에 대한 선호도 예측의 정확성이 감소되게 된다. 본 논문에서는 영화 추천 시스템에서 발생될 수 있는 초기 사용자 문제를 해결하기 위하여 사용자가 평가한 영화와 소셜 네트워크 서비스로부터 추출된 사용자 선호 장르를 활용하여 사용자 군집을 형성하고 이를 활용하는 방법을 제안한다. 소셜 네트워크 서비스로부터 사용자가 선호하는 영화 장르를 추출하기 위해 페이스북 페이지의 '좋아요' 옵션을 이용하며, 이 '좋아요' 정보를 분석하여 사용자의 영화 장르 관심사를 추출한다. 페이스북의 영화 페이지는 각 영화를 위한 페이스북 페이지로 구성되고 있으며, 사용자는 자신의 선호도에 따라서 "좋아요" 옵션을 선택할 수 있다. 사용자의 페이스북 정보는 페이스북 그래프 API를 활용하여 추출되고 이로부터 사용자 선호 영화를 알 수 있게 된다. 시스템에서 활용되는 영화 정보는 인터넷 영화 데이터베이스인 IMDb로부터 획득한다. IMDb는 수많은 영화와 TV 프로그램을 보유하고 있으며, 각 영화에 관련된 배우 정보, 장르 및 부가 정보들을 포함한다. 논문에서는 사용자가 "좋아요" 표시를 한 영화 페이지를 이용하여 IMDb로부터 영화 장르 정보를 가져온다. 그리고 추출된 영화 장르 선호도와 본 시스템에서 제안하는 영화 평가 항목을 이용하여 유사한 이웃 사용자 집단을 구성한 후, 사용자가 평가하지 않은 아이템에 대한 선호도를 예측하고, 높은 예측 값을 갖는 아이템을 사용자에게 추천한다. 본 논문에서 제안한 사용자의 선호 장르 기반의 사용자 군집 기법을 이용한 시스템을 평가하기 위해서 IMDb 데이터 집합을 이용하여 사용자 영화 평가 시스템을 구축하였고 참가자들의 영화 평가 정보를 획득하였다. 페이스북 영화 페이지 정보는 참가자들의 페이스북 계정과 페이스북 그래프 API를 통해 획득하였다. 사용자 영화 평가 시스템을 통해 획득된 사용자 데이터를 제안하는 방법에 적용하였고 추천 성능, 품질 및 초기 사용자 문제를 벤치마크 알고리즘과 비교하여 평가하였다. 실험 평가의 결과 제안하는 방법을 적용한 추천 시스템을 통해 추천의 품질을 10% 향상시킬 수 있었고, 초기 사용자 문제에 대해서 15% 완화시킬 수 있음을 볼 수 있었다.
