The objective of this research was to evaluate the inhibitory activities of phenolic compounds isolated from mulberry (Morus alba) leaves of 109 types against α-amylase and α-glucosidase. The inhibitory activity of the water extracts from Morus alba cv. Kuksang against α-amylase and α-glucosidase were determined as 93.8% and 48.7% respectively. The total phenolic content of extracts from Morus alba cv. Kuksang was 9.7±0.2 mg/g soluble in water and 14.3±0.2 mg/g soluble in ethanol. The inhibitory activity of the water extracts from Morus alba cv. Kuksang at 200 μg/ml phenolics concentration against α-amylase and α-glucosidase were determined as 100% and 82.6% respectively. The purification of inhibitory compounds was carried out by Sephadex LH-20 and MCI-gel CHP-20 column chromatography using a gradient elution procedure by nomal phase type (EtOH→distilled water) and reverse phase type (distilled water→MeOH). The quercetin was confirmed to be the chemical structure of the inhibitory compound against α-amylase and α-glucosidase by spectroscopic analysis of FAB-MS, NMR and IR spectrum.

Pomegranate (Punica granatum L.) which is very rich in Polyphenols and tannins was recently reported its anti-oxidant activities and phytoestrogenic activities in vivo test and many clinical studies, but the effects of them on the skin have not been reported. The experiments were tarried out in vitro to determine anti-oxidant activities of pomegranate extracts on DPPH radical scavenging assay, NBT/Xanthine Oxidase-superoxide scavenging assay, silica-induced intracellular $H_2O_2$, hydroperoxide and superoxide generation assay in RAW 264.7 cells. It showed that the methanolic extract of dried pomegranate peels have the most significant anti-oxidant activities on free radical scavenging assay and inhibitory activities on silica-induced intracellular free radical generation in RAW 264.7 cells. The concentrated juice of pomegranate showed only DPPH radical scavenging activities and inhibited hyaluronidase activity. Moreover, pomegranate seed oil inhibited specially silica-induced intracellular hydroperoxide generation in RAW 264.7 cells. These results suggest that the methanolic extract of dried pomegranate peels and pomegranate seed oil have more anti-oxidant activity than concentrated juice of pomegranate. Thus the extracts of pomegranate peels and seed oil could be developed cosmetic ingredients for anti-aging.

This study is to examine the section-based stream management with environmental characteristics and user monitoring. In Jeonjucheon, upstream section located near to Jeonju Hanok village has very good water quality and natural stream landscape. In case of mid/down streams, water quality is good and heavy concentration of facility leads to high use rates of these sections. The questionnaire consists of 5 parts: user characteristics, use behavior, citizen participation, importance rank, and Importance-Satisfaction(IS). 383 out of 454 responses with listwise deletion are used for demographic analysis and IS Analysis. In terms of citizen participation through 'ecological experience activity' and 'stream stewardship activity', 'occasional participation' shows the average of 78% in all three sections. For importance rank, the results arranged in order of priority show 'water quality' > 'green corridor' > 'trail' in up/down streams and 'water quality' > 'vegetation management' > 'trail' in midstream. Therefore, 'water quality' appears to be the most important variable among 13 variables. At last, the results of ISA indicate that all 10 variables need to be improved as satisfaction is lower than importance. In addition, 'plant management' variable falls into 'concentrate here' quadrant where importance is high and satisfaction is low.

This paper was intended to empirically identify problems with recreational sea fishing park facilities installed to help reinvigorate local economy of fishing villages in order to mitigate shortage of fishing facilities amid an increase in sea fishers and spur evolution of sea fishing into a marine leisure activity, on which basis this researcher presented direction for facility planning which is deemed necessary to map out the plan for sea fishing parks, along with measures designed to improve sea fishing park facilities. To analyze the problems related to sea fishing park facilities, we conducted a survey on facility operations involving 9 sea fishing parks and 2 sea ranches and had an investigative interview with facility manager. Moreover, a survey was conducted of fishers in 25 sea fishing places, including sea fishing park, fishing experience village, etc., in order to investigate their demand for facilities. The results of survey suggested that there was a significant demand for expansion of amenities such as safety facilities, toilets, lounge facilities, etc., which can accommodate the increase in the number of people fishing with family. Furthermore, the results showed that there was a huge demand for introduction of facilities aiding leisure activities in addition to facilities for fishing activities including education facilities such as fishing site at the corner exclusive for beginners, experiential facilities, camping site, seaside park, promenade, etc. Thus, sea fishing park should be the complex leisure space with a focus on fishing activities and requires facility configuration and facility planning suited to activity requirements within fishing park.

The purpose of the study is to analyze the operational case of gap year which can explore about guidance in some times before college entrance or during college life in the universities of main nations(England, American, and Japan) and draw from some implications for possibility of it's introduction in Korean university. It means that before students enter the college after finishing high school, they have various guidance activity and voluntary service activity for experiencing self-understanding out of regular curriculum. The study analyzed four universities in America, two universities in England, and one university in Japan. The main results indicate that the gap year can divide into system and university assisting finance. Based on the results and their implications of gap year case analysis in universities of England, America, and Japan, the study suggests that it needs to consolidate the related system of university and assist some finances, and systematic steps such as career exploration, career decision-making, career plan, and career preparation should be constructed.

This study intends to examine general hospital workers' health promoting lifestyle practice and figure out related factors to it. To achieve that, it conducted a survey with an unsigned self-reported questionnaire to the subject of 580 workers at hospitals located in Daejeon. The degree of practice in the subjects' health promoting lifestyle, the average of the entire questions was 2.26 points and the average of sub-sections was as in the following: 2.62 for interpersonal relations, 2.58 for spiritual growth, 2.26 for nutrition, 2.16 for stress management, 2.00 for health responsibility and 1.89 for physical activity Thus, the section of interpersonal relations showed the highest practice rate, whereas the section of physical activity demonstrated the lowest one. According to the multivariate regression analysis by phase, main factors affecting their health promoting lifestyle practice were selected as stress, attendance in education on health promotion, subjective heath condition, and age. The above results imply that general hospital workers' health promoting lifestyle practice is not sufficient and various factors are involved in it. Accordingly, it is considered that in order to enhance general hospital workers' attention to health promoting lifestyle practice, it is necessary to develop health promoting strategies and programs.

Eighty-nine shoulders in eighty-eight patients with traumatic unilateral anterior shoulder instability were evaluated for Rowe and UCLA scores, recurrence, return to activity, and range of motion by an independent examiner at an average of 39 months after either arthroscopic or open Bankart repair using suture anchors. The arthroscopic technique included a minimum of 3 anchors, and a routine incorporation of capsular plication and proximal shift. Twenty­six shoulders(86.6%) out of thirty in the open Bankart repair group had excellent or good results while fifty­four(91.5%) of the fifty-nine shoulders with arthroscopic Bankart repair had excellent or good results. The arthroscopic group revealed significantly better results in the Rowe(p=.041) and UCLA scores(p=.026). Two shoulders in each group developed redislocation. There were no significant differences in the loss of external rotation and return to prior activity between the two groups(p>.05). The residual instability occurred more frequently in the group of patients with lesser anchors. Arthroscopic suture anchor capsulorraphy has results equal to or better than the open Bankart procedure.

In this paper, we propose a MapReduce-supported clustering technique for collecting and classifying distributed workflow enactment event logs as a preprocessing tool. Especially, we would call the distributed workflow enactment event logs as Workflow BIG-Logs, because they are satisfied with as well as well-fitted to the 5V properties of BIG-Data like Volume, Velocity, Variety, Veracity and Value. The clustering technique we develop in this paper is intentionally devised for the preprocessing phase of a specific workflow process mining and analysis algorithm based upon the workflow BIG-Logs. In other words, It uses the Map-Reduce framework as a Workflow BIG-Logs processing platform, it supports the IEEE XES standard data format, and it is eventually dedicated for the preprocessing phase of the ${\rho}$-Algorithm that is a typical workflow process mining algorithm based on the structured information control nets. More precisely, The Workflow BIG-Logs can be classified into two types: of activity-based clustering patterns and performer-based clustering patterns, and we try to implement an activity-based clustering pattern algorithm based upon the Map-Reduce framework. Finally, we try to verify the proposed clustering technique by carrying out an experimental study on the workflow enactment event log dataset released by the BPI Challenges.
