Objectives The aim of this study is to develop a structured clinical protocol related with acquisition of radial pulse wave in the randomized, $2{\times}2$ cross-over design, and cold-heat intervention trial for a pilot and preliminary study. Methods The protocol was contrived based on wide ranging literature searches for cold-heat intervention experiments and radial pulse diagnoses. Results Sample size of 60 subjects was calculated based on an effect size derived from the previous study designed to detect the pre-post cold-heat differences in the radial pulse. Each subjects will be randomly assigned to the cold (first) to heat (last) group (n=30) or heat (first) to cold (last) group (n=30). All subjects will fill out a case report form and questionnaires related with pattern identification, dietary patterns, sleep quality, and physical activity will be surveyed and used as a secondary outcomes. Safety assessment will be reported at the final stage. Conclusions This protocol will provide an additional reference to future studies related with observation of radial pulse during any interventions and also expect to be used as a guideline for acquisition of reliable radial pulse wave data.

Purpose: In this study, we revealed the influence of customer buying factors in the purchase process of eco-friendly product. Especially, we focused on the information acquisition, alternative evaluation, and after-purchase activity process based on Korea-China customer's survey. Methods: In the information acquisition process, we investigate the channels of information acquisition about eco-friendly product, a reliability of information, and an impediment of acquiring product information. At the stage of alternative evaluation, we extract various causes that affects pre-purchasing process and perform the AHP analysis to identify critical causes. At last, we compare several factors which affects before and after purchasing process. Results: Especially, an average utilization and cognition score of eco-friendly products of Chinese consumers is higher than Korean consumers' score. In addition, critical buying factors of Korean consumers are a product quality, an evaluation of existing users. However, that of Chinese consumers are safety of products and environmental benefits of products. Conclusion: In recent years, as the rapid economic development of China, environment pollutions like heavy smog and yellow dust have been occurred frequently. In that manner, Chinese consumer's environmental consciousness is rapidly increasing; not only try to be active participant in eco-friendly activities, but also eco-friendly purchasing activities. In addition, Chinese consumers recognize eco-friendly products as good products made with advanced technology.

It is widely agreed that a documentation strategy that considers the social context of fragmented records is needed for documentation of social memories. This paper examined a new methodology named Seoul Narrative Archiving Policy(S-NAP) which was developed for the documentation of social memories in metropolitan areas. Also, the paper reviewed the applicability of S-NAP through the collection cases of Seoul Metropolitan Archives. The development process of the S-NAP is as follows. First, acquisition topic domains that cover an entire metropolitan region were developed. Next, implementation units(S-NAP) were designed through extensive data analysis that encompasses social, economic, culture, and art areas and reflects outcomes of regional studies. As a result, a total of nine acquisition topic domains, 61 parents S-NAP, and 184 children S-NAP were derived from the aforementioned methodology and methods. Finally, this paper proposed the applicability of S-NAP as archival contents and as a supportive tool for archival activity networks.

The wearable sensor glove was developed using EDA sensors and conducting fabric. EDA(Electro-dermal Activity) signal is an electric response of human skin. There are SIL(Skin Impedance Level) and SIR(Skin Impedance Response) in EDA. SIL consists mostly of a DC component while SIR consists of an AC component. The relationship between drowsiness and the EDA signal is utilized. EDA sensors were made using a conducting fabric instead of AgCl electrodes, for a more suitable, more wearable device. The EDA signal acquisition module was made by connecting the EDA sensor gloves through conductive fabric lines. Also, the EDA signal acquisition module can be connected to a PC that shows the results of the EDA signal processing analysis and gives proper feedback to the user. This system can be used in various applications to detect drowsiness and prevent accidents from drowsiness for automobile drivers.

Delivering the weapons system requirements of the military to the acquirer is an essential activity for the development of the defense industry as well as the successful acquisition of a weapons system. In order to ensure successful delivery of requirements, the creation of a weapons system Operational Requirements Document(ORD) has been mandated since 7. 2013. However, according to the results of a study which analyzes recently-created ORD, a number of problems are occurring. For one, some items in created ORDs differ from what the ORD template requires. In addition, the overall mission area of the weapons system to be acquired and the core parts(operation performance, system performance, and core performance) of ORD are being poorly recorded. In response, this study presented a framework(focused on a creating method of overall contents and core parts) for the creation of ORDs which can solve the problems that arose during ORD creation in the past.

Many organizations facilitate a host of online knowledge sharing communities to assist internal knowledge sharing and operation. The permeable boundaries and voluntary structures of online communities allow individuals to span community boundaries and affect member resources and structures. Although much research has been done on members' knowledge contribution in online communities, relatively little is known about how a member's contribution to a community is shaped by the cross-level interactions of member's external boundary spanning and the community's environmental scanning or membership fluidity. Drawing from the theoretical lens of boundary spanning and the external view of online communities, we take a multi-level approach in the analysis of the activities of 1,992 members of 126 communities internal to a global company. We find that a member's external boundary spanning activity (e.g., external knowledge acquisition via reading posts) has a positive effect, though at a decreasing rate, on subsequent internal knowledge contribution (e.g., posting replies in the member's home community). This positive effect is stronger in communities that are more active in environmental scanning or have fluid membership and weaker in communities that are less active in environmental scanning or have stable membership.

In this study, the psycho-physiological response of drivers was investigated in terms of EEG(Electroencephalogram), especially with the fractal dimensions computed by Chaotic algorithm. The Chaotic algorithm Is well Known to sensitively analyze the non-linear information such as brain waves. An automobile with a fully equipped data acquisition system was used to collect the data. Ten healthy subjects participated in the experiment. EEG data were collected while subjects were driving the car between Won-ju and Shin-gal J.C. on Young-Dong highway The results were presented in terms of 3-Dimensional attractor to confirm the chaotic nature of the EEG data. The correlation dimension and fractal dimension were calculated to evaluate the complexity of the brain activity as the driving duration changes. In particular, the fractal dimension indicated a difference between the driving condition and non-driving condition while other spectral variables showed inconsistent results. Based upon the fractal dimension, drivers processed the most information at the beginning of the highway driving and the amount of brain activity gradually decreased and stabilized. No particular decrease of brain activity was observed even after 100 km driving. Considering the sensitivity and consistency of the analysis by Chaotic algorithm, the fractal dimension can be a useful parameter to evaluate the psycho-physiological responses of human brain at various driving conditions.

In order to make an efficient prescription and cope with dementia, learning and memory functions of Sprague-Dawley model rats were tested with Morris water maze. And to evaluate the effect of the sample drug(CHM) on choline acetyltranferase and acetylcholine esterase, immunoreactive measurement and enzymatic activity measuring were carried out. Rats were injected with ibotenic acid through hippocampus CA1 and CA3 area. The results are as following. CHM improves the learning ability in the acquisition test and memory function in the retention test significantly. And CHM increases the level of AChE which is resolving acetylcholine. Though it doesn't increase the level of ChAT significantly which is synthesizing acetylcholine, but it shows the tendency of increase. So these results show that CHM improve the cholinergic catabolism and anabolism, and the increment of metabolic activity of cholinergic system. Thus it can be concluded that CHM will be helpful to cholinergic brain disease induced by primary or senile reduction of acetylcholine secretive activity.

In order to make the efficient prescription and cope with various senile dementia, learning and memory functions of Sprague-Dawley model rats were tested with Morris water maze at first. And to evaluate the effects of the sample drug(GM) on choline acetyltranferase and acetylcholine esterase, immunoreactive measurement and enzymatic activity measuring were carried out. Rats were injected with ibotenic acid through hippocampus CA1 and CA3 area. The results are as following. GM improves the learning ability in tile acquisition test and memory function in the retention test significantly. And GM increases the level of ChAT which is synthesizing acetylcholine in CA3 area, and at the same time it increases the level of AChE which is resolving acetylcholine. These results show that GM improve the cholinergic catabolism and anabolism, and the increment of metabolic activity of cholinergic system contributes to the recovery of damaged learning and memory function by ibotenic acid. So it can be concluded that GM will be helpful to cholinergic brain disease induced by primary or senile reduction of acetylcholine secretive activity.
