Purpose: This study was done to identify the effects of individual postpartum breast-feeding education on adaptation, attitude and practice of breast-feeding in primiparas. Methods: A quasi-experimental nonequivalent design was used to examine the effects of individual postpartum breast-feeding education among primiparas. The data were analyzed using $x^2$-test, Fisher's exact test and paired t-test. Results: There was a significant difference in breast-feeding adaptation (t=-12.94, p<.001), breast-feeding attitude (t=-2.71, p=.011) and breast-feeding practice ($x^2$=16.47, p<.001) between the group education (experimental group I) and individual education after group education (experimental group II). Conclusion: The results indicate that individual education on breast-feeding compared to group education has more positive effects on increasing breast-feeding adaptation, attitude and practice in primiparas. This result also indicates that many primiparas should be given opportunities of various types of education to improve breast-feeding practice such as individual approaches and postpartum breast-feeding education programs.

We present a code which identifies individual clouds in crowded region using IMFORT interface within Image Reduction and Analysis Facility (IRAF). We define a cloud as an object composed of all pixels in longitude, latitude, and velocity that are simply connected and that lie above some threshold temperature. The code searches the whole pixels of the data cube in efficient way to isolate individual clouds. Along with identification of clouds it is designed to estimate their mean values of longitudes, latitudes, and velocities. In addition, a function of generating individual images (or cube data) of identified clouds is added up. We also present identified individual clouds using a $^{12}CO$ survey data cube of Galactic Anticenter Region (Lee et al. 1997) as a test example. We used a threshold temperature of $5\sigma$ rms noise level of the data With a higher threshold temperature, we isolated subclouds of a huge cloud identified originally. As the most important parameter to identify clouds is the threshold value, its effect to the size and velocity dispersion is discussed rigorously.

In this paper, we propose a new data fusion method to improve the performance of individual prediction models for time series data. Individual models used are ARIMA and neural network and their results are combined based on the weight reflecting the inverse of EWMA of squared prediction error of each individual model. Monte Carlo simulation is used to identify the situation where the proposed approach can take a vintage point over typical fusion methods which utilize MSE for weight. Study results indicate the following: EWMA performs better than MSE fusion when the data size is large with a relatively big amplitude, which is often observed in intra-cranial pressure data. Additionally, EWMA turns out to be a best choice among MSE fusion and the two individual prediction models when the data size is large with relatively small random noises, often appearing in tax revenue data.

본 연구에서는 피치추출 오류를 줄이고 피치간격의 변위에 적응할 수 있도록 피치간격을 정규화하지 않은 개별피치 펄스를 이용한 새로운 멀티펄스 음성부호화 방식(IP-MPC)을 제안하였다. 여기에서, 개별피치 펄스의 추출률은 남자음성에서 $96\%$, 여자음성에서 $85\%$를 얻을 수 있었으며, 개별피치 펄스를 이용한 IP-MPC와 자기상관법의 피치정보를 이용한 MPC를 평가한 결과, IP-MPC의 음질이 MPC의 음질에 비하여 상당히 개선되었음을 알 수 있었다.

This research analyze the impact factors that affect the PI resistance of securities brokerage salespersons during Process Innovation in securities companies focusing on the broker's individual personality. After reviewing some related literatures, a survey was conducted at a domestic securities company with the derived factors from a focus group of securities salesmen with over 10 year work experience. The results show that broker's individual propensity to innovation, individual customer relationship and individual flexibility are closely related to the PI resistance. By controlling such factors for salespersons, securities companies can boost the ability to meet and control the changing situation and management innovation.

Virtual project organization may be recognized as one of the promising business models in which many knowledge sources externalize through cross boundaries of knowledge-based organizations. This paper proposes a knowledge competence evaluation of virtual project organization based on the following perspectives: 1) Individual knowledge perspective, 2) Activity-oriented knowledge perspective, and 3) Knowledge-driven social network perspective. In the framework, individual knowledge competence having experienced or learned from knowledge-based activities and virtual networks in the project, should be evaluated according to the assumption that knowledge and collaboration competence depends on the activities and networks acquired proportionally by the past participation to projects. An illustrative SI example is given in order to validate the proposed evaluation and computing procedure.

The objective of this research is to identify a web portal's specific functions and layouts that are aligned with personality trait of an individual internet user. This first stage of the overall research project intends to check whether the research instrument, namely the NEO Five Factors Inventory (NEO-FFI), is applicable to assess the personality traits of Thai internet users. Based on these personality traits, text-based description of functions/layouts of a web portal was developed and given to professional designers to mock up example web portal pages. These web portal pages were in alignment with individual personality traits. Rating data on the functions/layouts corresponding to individual personality traits were collected from an online survey of 207 Thai internet users. Results showed that respondents gave more consistent rating to the functions/layouts close to their individual personality traits identified in the text-based descriptions than in the mocked-up web portal pages.

Technology acceptance model(TAM) has been widely used to predict the end-user's acceptance of a new IT/IS. We used TAM as a theoretical foundation to explain user's intention to use an Internet shopping mall. The theoretical model is tested with the questionnaires from 308 users of an Internet shopping mall. Results show that several individual characteristics such as Internet skills and self-efficacy have a significant impact on user's perception of usefulness and ease of use. Results also show that both perceived enjoyment and perceived usefulness of Internet shopping mall strongly predict intention to use the Internet shopping mall. However, perceived ease of use has no direct influence on intention to use the Internet shopping mall. Personal innovativeness and Internet skills also have a positive effect on perceived enjoyment. Therefore, Internet shopping mall managers have to consider intrinsic motivational factor(enjoyment) as well as extrinsic motivational factor(usefulness). In addition, individual characteristics should be emphasized to form the positive beliefs about using the Internet shopping mall.

Recent trend of business is characterized by a recognition of importance of knowledge asset. Especially, this phenomenon is receiving more momentum as our society goes digital rapidly. However, most of literature on knowledge management is based on knowledge circulation from the corporate point of view, not from individual viewpoint. In this regard, this paper is concerned with proposing knowledge circulation process and its efficiency from the individual perspective. We adopted structural equation model or SEM to prove the statistical validity of our research framework. Eight hypotheses were built and tested empirically, leading to the fact that the knowledge utilization and sharing of individuals have a positive impact on the knowledge management efficiency.
