이 연구는 투간 바라노프스키의 "영국 공황사론"을 중심으로 그의 경기변동론을 분석하여 다음과 같은 점들을 지적하고자 한다. 첫째, 투간은 판로이론을 기초로 한 공황의 주기성 이론을 구성하려고 했다는 점을 밝히고, 그것의 논리적 일관성이 부족하다는 점을 지적할 것이다. 둘째, 투간을 비판하는 논자들이나 옹호하는 논자들은 투간의 이론적 체계가 가진 문제점을 제대로 평가하고 있지 못했다. 과소소비론은 투간의 공황론을 소비를 무시한 불비례론으로 평가하였지만, 공황의 구체적인 발발 과정에 대한 투간의 논의는 제대로 평가하지 못했다. 바우어는 퇴장화폐가 포함됨 재생산표식론으로 투간의 주기적 공황론을 구현하려고 했을 뿐이다. 그러나 예외적으로 힐퍼딩만이 맑스의 공황개념에 기초하여 투간을 가장 적절히 비판하였고, 그것에 기초하여 주기적 공황의 문제를 해명하려고 하였다.

A long-term forecasting method for a new product in early stage of diffusion is proposed. The method includes a constrained non-linear least square estimation with the logistic diffusion model. The constraints would be critical market informations such as market potential, peak point, and take-off. Findings on 20 cases having almost full life cycle are that (i) combining any market information improves the forecasting accuracy, (ii) market potential is the most stable information, and (iii) peak point and take-off information have negative effect in case of overestimation.

Generally the price of agricultural products has much different characteristics from that of manufacturing products. If products have the limitation of long-term storage and the short period of cultivation, the price of products can be more unstable. Moreover, the price forecasting is very difficult because it doesn't follow any cycle or trend. However price can be regarded as risk instead of uncertainty if we can calculate the probability of price. Reliability analysis techniques are used for forecasting the price change of Chinese cabbage. This study aims to show the usability of reliability analysis for price forecasting. A price-forecasting model was developed based on weather data of the first 10 days of the full cultivating cycle (80 days) 70 days and the average price and standard deviation of wholesale market prices from 1996 to 2001 and applied to forecast the boom price, or the orice which is over the tolerance of market prices, of upland Chinese cabbage in 2002 and 2003. Applied results showed the possibility of boom price forecasting using reliability analysis techniques.

The purpose of this study was to investigate the present state of e-business according to the establishment year and the sales approach of Dongdaemun clothing market and to present problems according to e-business activation of it and its developmental direction. The subjects for this study were selected out of Dongdaemun clothing markets being considered as more fashion-oriented markets and were divided into two categories both according to the establishment year and according to the sales approach. As a result, Dongdaemun clothing markets are mainly divided into traditional wholesale market, eastern wholesale & retail market, and western retail market and having dealings with each other according to the market's characteristics. The utility percentage of on-line e-business according to the establishment year and the sales approach showed that traditional wholesale market was 42%, eastern wholesale & retail market 0.75%, and western retail market 11%. This result indicated that the utility percentage of traditional wholesale market showed much higher than eastern wholesale & retail market and western retail market. This would be because the structural characteristics of clothing market delayed the utility of e-business. For the problems on the utility of on-line e-business through counselling, traditional wholesale market showed much higher than wholesale & retail market and retail market because it had little problems on design imitation in retail market due to export by order and mass production. The problems of low utility of on-line e-business in Dongdaemun clothing market would result from well-timed on-line update according to rapid goods cycle, constant satisfaction for additional order, standardization of size and quality, and inexpensive internet purchase despite of express expense.

확산모형은 시장의 예측이나 그 방법론의 연구를 위해 마케팅에서 광범위하게 다뤄졌을 뿐 아니라, 경제학에서도 다양하게 활용되어 왔다. 특히 Bass 모형은 Rogers의 혁신확산 및 수명주기이론을 간단한 수리적 모형으로 표현할 수 있기에 혁신적 신제품의 채택과 확산을 설명하는데 널리 활용되었다. 그럼에도 불구, 확산모형은 '산업의 쌀' 이라 일컬어지는 반도체의 수요예측에 일부 선도적 연구를 제외하고는 활용된 바 없다. 이에 Bass 모형에서 진일보한 비선형회귀 접근법 확산모형을 활용, 전력반도체 중 전기전자기구의 필수 스위치로 채택되는 MOSFET의 수요를 추정하여 수명주기를 예측하고 그 과정을 설명함으로써 산업관계자는 물론 반도체와 전기전자산업 정책입안자에게 중요한 시사점을 전달하고자 한다.

This study investigated domestic and foreign cycle wear sizing systems for the domestic market and provided basic data for development of a high functional cycle wear with excellent fitness qualities. Each brand was found to have different dimension items and different sizes as well as size deviation and range according to each item. Therefore, a size selected by referring to the dimension items would be expected to have confusion when selecting a size. Domestic brands are able to selects sizes relatively easily because they suggest sizes mainly by height and weight (which are a universal size). However, the development of a sizing system for domestic cycle wear brands is needed because each brand have different sizes according to its dimension items. Foreign brands are also different from domestic brands in size marking items and sizes according to items. Therefore, the establishment of a sizing system standard for foreign brands is necessary because there could be a problem with fitness in the same sizes selected for domestic brands. Cycle wear is also able to cover various body types due to the elasticity of its material; however, and evaluation of fitness and a follow-up study will be necessary to develop cycle wear with a fitness that is proper for a Korean body type.

본 논문은 임대료시장의 주기변화에 따른 헤도닉 모형의 임대료 결정요인의 영향력 변화를 분석하였다. 임대료지수를 구축하여 분석한 결과 금융위기가 전환점이 되어 서울시 임대료 시장이 하락기와 상승기로 구분됨을 밝혔으며 주기에 따른 헤도닉 모형의 특성변수의 회귀모수 변화를 고찰하였다. 분석은 강남오피스와 도심오피스로 구분하여 실시하였으며 권역에 상관없이 일관된 변화를 보인 개별회귀모수로서는 토지가격, 지하철역에서의 거리, 건물규모, 건물연한 및 전환이율로 밝혀졌다. 상승기에는 건물의 규모가 클수록 임대료가 높아지는 경향이 있으며 건물이 오래될수록 임대료 하락요인으로의 영향이 커지는 경향이 있는 것으로 나타났다. 전환이율 역시 임대료에서 차지하는 비중이 상승기에 높아짐을 보여준다. 토지가격의 영향은 줄어들고 교통편의성의 장점은 약해지고 있어 상승기에는 지리적 이점의 영향력이 감소하고 건물 특성의 영향력이 상대적으로 커지는 실증적 증거를 제시하였다.

본 연구는 우리나라 종합병원을 대상으로 경영의 위험요인이 운전자본 관리에 어떻게 영향을 미치는지를 분석하였다. 자료는 의료기관회계정보공시 시스템을 이용하여 271개 종합병원 3개연도(2016년, 2017년, 2018년)의 회계정보를 이용하였다. 도입변수는 종속변수로 운전자본 수준과 현금순환주기, 독립변수로 운영위험과 시장위험, 통제변수로 운전자금 구성요인(현금, 매출채권, 재고자산, 매입채무)을 선정하였다. 연구결과, 우리나라 종합병원들은 운영위험이 낮을수록 운전자본 수준은 높았으며, 운전자본 결정에는 운영위험, 현금, 재고자산, 매입채무가 작용하는 것으로 확인되었다. 그리고 시장위험(의료이익률)이 낮을수록 현금순환주기가 높았다는 것을 알 수 있었다. 따라서 의료기관들도 운영의 특수성을 고려하여 경기대응능력을 갖출 수 있도록 운전자본 결정요인으로 확인된 운영위험, 현금, 재고자산, 매입채무의 적절한 관리방안에 대한 검토의 필요성이 제기된다.

In Korea, construction and development has been continued rapidly since the 1970s, and the reconstruction and renovation market has recently been activated to improve old buildings. Most of the environmental evaluation of reconstruction and renovation projects is focused on the use of operating energy, and It is necessary to analyze carbon emissions throughout the life cycle for a comprehensive evaluation of reconstruction and remodeling projects. Therefore, this study quantitatively predicted carbon emissions from reconstruction and renovation based on ISO 14040s through case analysis for the purpose of evaluating the carbon emissions of renovated buildings from the perspective of the whole life cycle. In additional, the amount of carbon savings of each was analyzed through comparison with existing building.

Faced with increasing competitive pressures to reduce time-to-market, many business organizations have recognized that shortening the design cycle by taking full advantage of their intellectual property is inevitable in maintaining their market share. This paper describes a knowledge management system for machine tool design. Product structuring, change management, and complex design knowledge management are possible through the developed system. The system can speed up the design process by making necessary data instantly available as it is needed and keeping track of all the relevant design information and knowledge including individual decisions, design intentions, documents, and drawings.
