This study is focused on the effects of one's blood type on emotional character and anti-stress by comparing each individual's brain wave. Observed records are from those kids who volunteered for KRIJUS(Korea Research Institute of Jungshin Science)'s brain wave measurement from September 2006 to December 2009. The whole 4636 adult(20-59 age) group consists of 3221 female and 1415 male. Blood types are as follows; A>B>O>AB dominately ordered. The result shown no relations between the blood types of adult and their emotional character. But meaningful difference had been revealed between the blood type and stress resistancy; type O rated higher scores in awarness and stress resistancy then other types, which shows that type O has more ability to redudce its stress. This study revealed meaningful relation between blood types and emotional character among several categoties, while suggesting follow-up researches figuring out more detailed explanations for its effect and genetic role.

For question-answering system, question analysis module finds the question points from user's natural language questions, classifies the question types, and extracts some useful information for answer. This paper proposes a question type classifying technique based on focus words extracted from questions and word semantic information, instead of complicated rules or huge knowledge resources. It also shows how to find the question type without focus words, and how useful the synonym or postfix information to enhance the performance of classifying module.

This study is aimed at searching for the ways to effectively cope with the conflicts found among the members of the hospitals by analyzing the conflict control practiced differently depending on the scale of the organization and characters of its members. The result of analysis into the types of conflict control by the members of the hospital comprising a multitude of manpower is presented as follows. 1. The hypothesis 1 which assumes that the sex will determine the type of conflict control is adopted in part at the level of p<0.05. 2. The hypothesis 2 which assumes that the working position will determine the type of conflict control is adopted in part at the level of P<0.05. 3. The hypothesis 3 which assumes that the age will determine the type of conflict control is adopted in part at the level of p<0.05. 4. The hypothesis 4 which assumes that the size of hospitals will determine the type of conflict control is adopted in part at the level of p<0.05. 5. The hypothesis 5 which assumes that the career will determine the type of conflict control is adopted in part at the level of p<0.05. 6. The hypothesis 2 which assumes that the educational background will determine the type of conflict control is adopted in part at the level of p<0.05. This study requires extended follow-up study to cover the cause of conflict and job satisfaction of the medical manpower.

This study investigated what kind of message forms and information sources more effect according to SNS' type and use intensity. To this end, this study did experimental analysis using collected data by survey which manufactured message forms and situational contents of information sources. According to analysis results, the effect of message forms showed difference according to SNS' type and use intensity. Realistic message showed greater effect in interest-based SNS and high use intensity. Evaluative message showed greater effect in relation-based SNS regardless of use intensity. The effect of information sources showed difference according to SNS' type. Friend or college and knower showed greater effect in relation- based SNS, and company showed greater effect in interest-based SNS. In the case of use intensity, friend or college showed the greatest effect without difference. Such results can provide a practical contribution in planning SNS advertising strategy. Future Studies need to expand survey variously into SNS and subject.

The purpose of this study is to classify body type by BMI and to inquire about body satisfaction and fitness apparel depending on body type among women 20-50years of age. As a result, body types are classified into three groups: lean, normal, and obese figures. On front silhouette, the normal type occupies most in women belonged to lean figure group, the obese lower part of the bodytype in normal figure group, and the obese upper part of the body type in obese figure group. On the other, in side silhouette, the slender type is prevalent in lean figure group, hip obesity in normal figure group, and trunk obesity in obese figure group. In particular, women in the obese figure group were distributed among the various body types. The obese figure group had a lower fitness apparel in the measurement of circumference(e.g., chest, waist, and hip) related to obesity in comparison with measurement of length. Therefore, the development of an optimal sizing system in response to the various body types in the obese figure group is needed to provide more diversity in aesthetic design and continuity among various sizing systems.

AI technology is being successfully introduced in many fields, and models deployed as a service are deployed with black box environment that does not expose the model's information to protect intellectual property rights and data. In a black box environment, attackers try to steal data or parameters used during training by using model output. This paper proposes a method of inferring the type of model to directly find out the composition of layer of the target model, based on the fact that there is no attack to infer the information about the type of model from the deep learning model. With ResNet, VGGNet, AlexNet, and simple convolutional neural network models trained with MNIST datasets, we show that the types of models can be inferred using the output values in the gray box and black box environments of the each model. In addition, we inferred the type of model with approximately 83% accuracy in the black box environment if we train the big and small relationship feature that proposed in this paper together, the results show that the model type can be infrerred even in situations where only partial information is given to attackers, not raw probability vectors.

In this paper, we examine the relationship between information type and new product development process. Information that was provided for new product development can be divided into two categories. One was relative information that could be used as a basis for comparison such as patent data. The other was absolute information that must be fulfilled in the new product such as key customers requirements. An experiment was conducted with staffs in an R＆D department in order to analyze the impact of the different information types on the development process of new product. It was found that the group with the absolute information recognized the given information repeatedly, which in turn results in a highly technical idea with good teamwork. The group with the relative information created a superior product with better application, appearance and product efficiency through the frequent refinements of given ideas. This paper concludes with the implications of the results to the new product development process and supporting information systems.

In this paper, the Si vertical Hall devices ale fabricated by using standard bipolar process and investigated in terms of the opeating and noise properties. The sensitivity of device with P+ isolation dam(type B) has been increased up to about 1.2 times compared to that device without the dam also noise has been increased. With the condition of f=I[KHz], band-width 1[Hz], the resolution of magnetic-field detection were about $0.97[{\mu}T]$/ type B and $1.25[{\mu}T]$/ type A, respectively, thus we must consider correlation the low noise or good resolution and high sensitivity in the situation for device geometry design or even for the materials.

We consider the problem of oscillation and nonoscillation solutions for unstable type second-order neutral difference equation : $\Delta^2(x(n))-p(n)x(n-\tau))=q(n)x(g(n))$. (1) In this paper, we obtain some conditions for the bounded solutions of Eq(1) to be oscillatory and for the existence of the nonoscillatory solutions.
