우리나라는 글로벌 기술경쟁력 제고를 위해 연구개발에 대한 투자를 지속적으로 증대시켜왔다. 우리나라의 GDP대비 연구개발투자비는 4.15%로 세계 1위 수준이며, 이 가운데 기업부문은 전체 투자의 78.5%를 차지하며 매우 중요한 역할을 수행하고 있다. 그러나 더 이상 양적인 투자 증대에는 한계가 존재하기에 R&D투자에 대한 질적 수준을 높여 효율성을 제고하기 위한 노력이 절실히 필요한 실정이다. 이러한 연유로 본 연구에서는 기업의 경영성과를 제고하기 위한 방안을 강구하기 위한 연구를 수행하였다. 이를 위해 그동안 학문적으로 그 중요성이 강조된 연구개발 초기 단계인 기술전략과 기술기획 역량이 기업의 성과제고에 미치는 영향요인을 실증적으로 검증하고자 하였다. 실증분석 결과, 기술전략과 기술기획 활동이 경영성과 제고에 매우 유의미한 영향을 미치는 것으로 나타났으며, 조직유연성의 경우 개별적인 요인 또한 중요하지만 기술기획 활동을 긍정적으로 조절하여 경영성과 제고에 기여함을 확인하였다. 본 연구에서는 기업의 기술혁신 활동을 실제적으로 파악하기 위해 기업연구소를 운영하고 있는 전체 기업을 대상으로 표본조사를 수행하였으며, 분석방법으로는 다중회귀분석과 분위회귀분석을 활용하였다.

개인투자자 10,000명의 1998년부터 2003년까지 6년간의 거래자료와 잔고자료를 분석한 결과, 개인투자자들은 총수익률(gross return) 기준으로 연간 12.3%의 수익률을 실현한 것으로 나타났다. 동기간에 거래소 시장의 가치가중평균수익률은 13.6%였으며 코스닥 시장을 포함하는 종합시장수익률은 9.7%를 기록하였다. 그러나 거래비용을 고려한 순수익률(net return)은 연간 8.3%로 하락하여 시장수익률보다 크게 낮은 것으로 나타났는데, 연간 270%가 넘는 거래 회전율이 투자성과에 부정적인 영향을 미친 탓이라 할 수 있다. 특히 잔고규모별 초과수익률 분석에서는 투자금액이 상위 20%에 속하는 투자자들은 시장수익률과 비슷한 수준의 수익률을 얻은 반면, 나머지 80%의 투자자들은 시장수익률과 커다란 차이를 보였는데, 왜 많은 개인 투자자들이 시장을 떠나는지를 확인시켜 주는 결과이다. 특기할 사항은 과잉확신으로 인해 거래량이 증가하고 기대효용은 낮아진다는 과잉확신 모형을 지지한다는 점이다. 분석대상인 개인투자자들은 고 베타 주식과 소형주와 가치주를 선호하는 것으로 나타났다.

Purpose - This study investigates the performance of investment strategies incorporating estimated stock market cycle based on a lead-lag relationship between business cycle and stock market cycle, thereby deriving empirical implications on risk management. Design/methodology/approach - The data period ranges from June 1953 to September 2022 and de-trended short rate, term spread, credit spread, stock market volatility are considered as major input variables to estimate business cycle and stock market cycle by applying probit model. Based on the estimated stock market cycle, two types of strategies are constructed and their performance relative to the benchmark is empirically examined. Findings Two types of strategies based on stock market cycle are considered: The first strategy is to long(short) on stocks when stock market stage is expected to be an expansion(a recession), and the second one is to long on stocks(bonds) when expecting an expansion(a recession). The empirical results show that the strategies based on stock market cycle outperforms a simple buy and hold strategy in both in-sample and out-of-sample investigation. Also the out-of-sample evidence suggests that the second strategy which is in line with asset allocation is more profitable than the first one. Research implications or Originality The strategies considered in this study are based on the estimated stock market cycle which only depends on a few easily available financial variables, thereby making easier to establish such a strategy. It implies that investors enhance investment performance by constructing a relatively simple trading strategies if they set their position on stocks or choose which asset class to buy conditioning on stock market cycle.

The measurement and management of patient satisfaction has become one of the key issues in the last two decades. Hospitals must thoroughly understand the needs of their customers and design products and health services that meet and exceed their expectations. The importance-performance analysis(IPA) is a widely used analytical technique that yields strategies for managing customer satisfaction in a variety of applications. IP A is a two-dimensional grid based on customer-perceived importance of quality attributes and attribute performance. Depending on the interplay of these two dimensions, four strategies can be derived. The aim of this study is to develop the management strategies for improving patient satisfaction in university hospitals using the I-P analysis. The attributes on inpatient service quality in 4 university hospitals was investigated using the Martilla and James(l977)' s a mean adjusted I-P grid where the axes of the grid cross at the average rating point of all items. The patient satisfaction questionnaires were completed by 600 hospital inpatients. The main statistical methods are path analysis and IPA with SPSS 12.0 and AMOS 4.0 statistical softwares. The two attributes, physician and medical service, administrative staff kindness attributes position in first quadrant(Keep Up the Good domain). The nurse and nursing service attributes position in second quadrant(Possible Overkill domain). The two attributes, convenience of check-in service, facilities and physical environment position in third quadrant(Low Priority domain). Finally the quality of inpatient service(food etc.) attributes position in fourth quadrant(Concentrate Here domain). These findings show various implications on the development of strategies in university hospitals in the future. It was determined that quality of inpatient service(food etc.) need to concentrate more on investments. These investments include a taste, price, proper provision of food service and quick response of pain management. A low priority was given to investment in streamlining the check-in process of inpatient and hospital facilities and physical environment in the long run.

This study analyzes expression methodology and aesthetic meanings in modern hair ornaments that adopt maximalism. Maximalism has appeared in various hair ornaments throughout history. Hair dresses are used for many reasons related to class, social position, religious beliefs, and occupation throughout the Eastern and Western hemispheres. A higher class and social position was often denoted by a fancier and bigger hairdress. In modern society maximalism is expressed in literature, expressionism, maxi-marketing, exaggerative advertisements, and symbolic architecture. Formative expression methodologies in modern hair ornaments that adopt maximalism are transform, overlapping & exaggeration, and mixing & edition. The aesthetic meanings of maximalism in hair ornaments are the reinterpretation of retro ornaments, the exaggeration of internal self-expression, humorous symbolic objects, and the conveyance of a social critical message. The advantages of maximalism help people communicate and co-provide an abundant life. These are expected to create significant and numerous positive impacts in society. In addition, the continued efforts on the investment in hair ornaments that express Maximalism well as a fashion trend shows that further study on the persistence, practicality and recognized design inconvenience in the aesthetic value are needed.

When turning to determining a subject position for the digital age, one may look beyond the invention of its technologies and instead begin with the development of its aesthetic of networked communities, nodal expression, and collaborative identity. Virginia Woolf's The Waves demonstrates this aesthetic in both form and content. In this paper, I will examine the role of collaboration in the form of interdisciplinary composition, arguing that Woolf's use of musical form and dramatic monologue and dialogue structurally secure an investment in collaborative models of expression. Digital texts taut their inherent multimodality, but such compositions are also evident in pre-digital texts. In addition, I will decipher the subject position Woolf puts forward in The Waves by looking closely at how the characters determine their own identity and existence when they are alone, when they interact with one individual, and when they congregate as a group. These are exemplified more specifically in the representations of Rhoda and Bernard as equally refusing to collaborate between a self-defined identity and a group defined identity; Bernard's channeling of Lord Byron while writing a love letter; and Woolf's use of the red carnation as a repeated image of the intertwined nature of the characters' collaborative identity and mutual dependence on one another.

Space development has been led by the state due to huge investment, risks of development failure, and restrictions on international cooperation on technology development and transfer. For this reason, it has been developed mainly by some advanced countries and industrial network formed among them. However, Korean space industry is being promoted by the successful launch of 'KSLV-I' and 'CAS 500-I' and the space launch vehicle "KSLV-II" under development. Recently, Korea and U.S. agreed to end bilateral missile guidelines. Therefore it is expected that development of Korean space industry will be accelerated due to the disappearance of the constraining factors for the development of space launch vehicles. Accordingly, this study examined the development and formation of the Korean space industry through the framework of network analysis. Based on this, the effect of structural position in the industrial network as a resource on the performance of Korean space companies was examined. Panel analysis was applied. Through this study, ideas for fostering the domestic space industry and implications for national policy related with building an industrial ecosystem are derived. It contributes to the development of space industry in Korea.

The present research has been conducted on the arranged form, the number and kinds, the area, the location of the rooms and the variation on exterior designs, based on a layout and a ground plan of each step, which are general plan, VE proposal and the final negotiation, for 11 elementary and middle and high schools that are designed in the way of BTL project. In consequence, it has been found out that there are some changes in the number and position of the rooms. However, the changes are not exceeding the overall arrangement form. This could not have led to the original aim, which is to induce creativity by PFI. It can be supposed that it is because the BTL system is stick to the old process, the method of financial investment and it is true to say that there needs to be solution for that.
