마케팅 교육의 미시적, 거시적 편견

황용철 濟州大學校 地域社會發展硏究所 1997 논문집 Vol.34 No.1

마케팅시스템의 목표는 소비자들이 그들 스스로 정의하고 표현하는 소비자들의 필요와 욕구, 욕망을 만족시키는 것이라고 종종 말하곤 한다. 마케팅컨셉 (marketing concept)에 의하면 마케팅시스템의 목표를 달성하는데 있어 촉진제로서 마케팅과 마케터를 생산자와 소비자 사이에 위치시킨다. 이 논문은 마케팅교육자들이 마케팅컨셉의 참뜻을 구현하고자 한다면. 그들의 교육과정에 다양한 여러 가지 대안적인 견해들을 채택해야 함을 주장한다. 본고에서는 우선 현대 마케팅에 대한 비판적인 사고(critical thought)를 대략적으로 살펴보고 난 연후에 이의 주요 내용을 마케팅의 전통적인 사고와 대비시켜 살펴보고자 한다. 이를 위해 마케팅에 대해 비관적인 몇가지 견해가 제시되며. 전통적인 견해와 대비된다. 그리고 이와 관련된 몇가지 주요한 학자들의 논문내용이 제시되고 요약된다. 또한 마케팅시스템의 최종 목표가 위에서 언급한 바라고 할 때. 각각의 대안적 견해들이 마케팅 커리귤럼에 포함되어야 하는 이유에 대한 설명들이 논의된다. 끝으로 한 학기 동안의 소비자행동에 관한 교과과정에 다양한 대안적 견해들 을 통합하는 데 있어서 졸자의 개인적 경험들을 소개하고 재검토하였다.

This study was performed to evaluate the prevalence of spinal disorders in dogs, as well as their breed, age, gender and body weight distributions. Seventy cases of caine spinal disoreders presented in the period 2001 and 2006 were reviewed. The diagnosis was obtained by survey radiographs, myelogram, CSF analysis, CT and MRI. The most frequent breed was Maltese(15 cases), and followed by Yorkshire Terrier (10 cases), Pekingese (9 cases). Canine spinal disorders occurred from 7 month to 17 year old dog, mean age was 5.3±3.7 year-old. Canine spinal disorders occurred more often in females(59.7%) than males. Mean body weight was 5.87±7.02 kg. Degenerative (39 cases, 43.3%) and anomalous (24 cases, 26.7%) disorders were dominant in 90 specific disease distribution. This results can be a reference data for the further study.

치은연하 파절로 치조골 소실을 동반한 상악측절치에서 orthodontic extrusive remodeling후 임플란트 식립을 통한 심미수복 : 증례보고

황수연,손원준,한영철,배광식,백승호,이우철,금기연 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.1

심미적으로 중요한 전치부에서 단일 치아 임플란트를 이용한 보철수복은 임상의에게 새로운 도전과제 중의 하나가 되었다. 그러나 전치부에서 single-unit implant는 식립할 부위의 치조골 상태가 양호해야 하는데 치은연하 파절로 인해 치아 주위에 골 손실이 있는 경우 immediate implant는 심미적으로 문제를 야기할 수 있다. 따라서 본 증례는 "orthodontic extrusive remodeling"을 통해 파절치와 주위 조직을 교정적으로 정출시켜 임플란트 식립을 위한 연조직과 경조직을 증대시킨 후 임플란트 식립을 통해 상악측절치에서 성공적인 심미수복을 이룬 증례에 관한 것이다. The treatment of esthetic areas with single-tooth implants represents a new challenge for the clinician. In 1993, a modification of the forced eruption technique, called "orthodontic extrusive remodelling" was proposed as a way to augment both soft- and hard-tissue profiles at potential implant sites. This case report describes augmentation of the coronal soft and hard tissues around a fractured maxillary lateral incisor associated with alveolar bone loss, which was achieved by forced orthodontic extrusion before implant placement. Through these procedures we could reconstruct esthetics and function in a hopeless tooth diagnosed with subgingival root fracture by trauma.

The purpose of this study was to evaluate the skeletodental changes during treatment and retention period in Class Ⅱ malocclusion by conventional comprehensive edgewise appliances. In total 38 case, nonextraction group(20) and first premolar extraction group(18) were examined in this study. Skeletal changes, maxillary dental changes and mandibualar dental changes in treatment period〔T2-T1〕and retention period〔T3-T2〕were evaluated by superimposing the cephalograms in reference to cranial base, the palatal plane or mandibular plane, respectively. The results were as follows; 1. Both nonextraction group and extraction group showed significant increase in both anterior facial height and posterior facial height, but showed no significant steepening of occlusal plane in both treatment and retention. 2. In nonextraction group, maxillary incisors were retracted and extruded in treatment and slightly returned in retention. Maxillary molars were extruded with distal movement in treatment and slight returned in retention. Mandibular incisors were moved labially, mandibular molars were extruded with no mesial movement in treatment, and showed no significant changes in retention. 3. In extraction group, both maxillary and mandibular incisors were retracted and extruded in treatment and slightly returned with increase of interincisal angle in retention. Maxillary molars were extruded with mesial movement in treatment and returned in retention. Mandibular molars were extruded with mesial movement in treatment and showed no significant changes in retention.

To improve the therapeutic method for mastitis, treatment effect of chitosan pharmacopuncture was examined in three milking goats(A,B and C). Mastitis was artificially induced in two milking goats(A and B) and one goat(C) was naturally infected case with mastitis. The acupoint used was Yang-Ming and chitosan suspensions(provided from Tottory University, Japan: 30㎎ of chitosan/㎖)were injected to the acupoint with 5㎖/time for 3 days, respectively. As for the change of somatic cells in milk along with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in all udders of B. In addition, as for the change of total leukocyte counts of peripheral blood with chitosan pharmacopuncture, they showed a decreasing tendency after increase on the 3rd day in B and C except A which showed a increasing tendency until on the 7th day. In the change of neutrophil/lymphocyte(N/L) ratio, increasing tendency was seen in A and C but increasing tendency after slight decrease was observed in B. Further, in the change of serum total protein and A/G ratio, serum total protein content was decreased after slightly increase on the 3rd day in A, and they were decreased after increase until on the 7th day in B and C, respectively. As for the change of A/G ratio, different pattern increasing tendency was shown in A, B and C.

This study examines the long term trends of current inputs in Korean agricultural sector. For this, aggregative time series for current inputs was prepared: the value of current inputs in terms of 1985 prices. The annual data pertain to the period 1955~92. Current inputs may be defined as the inputs of tangible factors of production, whose values are fully transferred to their products within a single production period. Not only factors which are supplied to agriculture from the non-agriculture sector, but also those produced within agriculture are included to the extent that they agree with the above definition. However, self-supplied intermediate goods are excluded in this study. Current inputs are classified as follows: Fertilizers, Agricultural Chemicals, Seeds and Feeds. Using the data set estimated, we analyzes the characteristics of trends and structural changes of current inputs.

The wind resistant design of building generally used up to data has been based on the value of an extreme speed. The extreme speed is normally estimated from wind data observed for the return periods of last 50 years or 100 years on the basis of the importance of building to be constructed. However, it is essential to consider the time variance of wind action because strong winds originated by Typhoon or others are occationally coming for attack. This study is to examine the origin of occurence and the action time of strong wind, and to understand the time variance characteristics. Strong winds are divided into 3 parts such as the regional condition of Korea, namely Typhoon, Frontal system storm, and Monsoon. The areas reflecting the origin of 3 kinds of the strong winds are also devided are selected as such as Seoul-Kyongki, Jungbu, and South-seashore. The representative cities are selected as Seoul fro, Uljin and Kunsan for, and Busan and Yeosu for. Observed wind data of past 20 years will be employed to estimate duration and propability of wind velocity. The observed wind data are recorded with duration of 96 hours at the center that annual extreme wind speed takes place, and with the mean value of wind velocity during 10 minutes at 1 hour interval. Based on these investigations, the duration and probability of wind velocity should be estimated. Generalized probability distribution function of wind velocity will be proposed. Duration of strong winds presented as a function of its maximum wind velocity. From these results, multipling generalized distribution function by generalized number of (wind velocity) samples, approximate equation of wind-duration will be derived. Approximate equation of wind-duration proposed in this study should be useful for analysing fatigue damage of structures and time dependent analysis of structure under strong wind in Korea.

본 연구의 목적은 치간삭제 후 불소 및 수산화인회석 페이스트의 치면 도포에 대한 법랑질 표면의 결정구조 및 재광화를 평가하고자 하였다. 치간삭제 후 1.23% 인산화 불소 및 10% 수산화인회석 페이스트를 치면에 도포한 후 법랑질 표면의 결정구조 변화를 주사전자현미경으로 관찰하고, 법랑질 표면의 칼슘, 인, 불소 함량 등의 변화를 energy dispersive X-ray spectroscopy (ESD)로 분석하였다. 실험결과 10% 수산화인회석 페이스트 도포한 군에서 칼슘 함량이 증가하였고 (p < 0.01), 치간 삭제 후 거칠었던 법랑질 표면이 매끄럽고 부드러워졌으며 법랑질 결정구조가 작고 치밀해짐을 관찰할 수 있었다. 이상의 결과는 치간삭제 후 불소 및 수산화인회석 도포가 치면 결정구조 및 재광화에 유리하다는 것을 의미한다. The aim of this study was to evaluate the remineralization of interdentally stripped teeth after fluoride gel or hydroxyapatite paste application. Methods: After interdental stripping, 1.23% fluoride gel or 10% hydroxyapatite paste was applied three times a day, with a duration of four minutes, for a week. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to compare the change of surface contents and crystal structures before and after the application of fluoride gel or hydroxyapatite paste. Results: EDS analysis indicated that calcium contents were increased after 10% HAp paste application on stripped enamel (p < 0.01). SEM view showed that enamel surfaces in groups of 1.23% APF gel or 10% HAp paste application were smoother than those of control group, which was regarded as filling of the pore structure. And pores between crystal structures in groups treated with 1.23% APF gel or 10% HAp paste were smaller than those of control group. Conclusions: Application of APF or HAp on stripped enamel could positively influence on the surface contents or crystal structure.

This is a case report of difficult eruption of succeeding permanent tooth by periapical inflammation of primary tooth. 12-year-8-month-old girl who had been treated by pulpotomy of lower right second primary molar about 4 years ago was recalled for prolonged retention of it. Radiographs showed periapical inflammation of lower right second primary molar and horizontal buccal impaction of succeeding permanent tooth. Right second premolar seemed impossible to erupt so surgical extraction of it was done with removal of lower right second primary molar and resin space maintainer was manipulated for prevention of space closure and elongation of opposing tooth.
