  • The emerging technologies for the natural computer interaction can give manufacturers new opportunities of product innovation. This paper is the study on a method of human communication about a finger gestures interaction. As technological advance has been so rapid over the last few decades, the utilizing products or services will be soon popular. The purpose of this experiment are as follows; What is the usefulness of gesture interaction? What is the cognitive impact on gesture interaction users. The finger gestures interaction consist of poking, picking and grasping. By measuring each usability in 2D and 3D space, this study shows the effect of finger gestures interaction. The 2D and 3D experimental tool is developed by using LeapMotion technology. As a results, the experiments involved 48 subjects shows that there is no difference in usability between the gestures in 2D space but in 3D space, the meaningful difference has been found. In addition, all gestures express good usability in 2D space rather than 3D space. Especially, there are the attractive interest that using uni-finger is better than multi-fingers.

  • A new commercial strain "Gumbit" of golden oyster mushroom was developed by hyphal anastomosis. It was improved with hybridization between monokaryotic strain derived from ASI 2295 and ASI 2703. The optimum temperature of mycelial growth and fruiting body development were $25{\sim}30^{\circ}C$ and $19{\sim}24^{\circ}C$, respectively. The pileus was golden to brilliant yellow color. Commercial strain "Gumbit" was not as prolific as the more commonly cultivated Pleurotus ostreatus in the conversion of substrate mass to mushrooms. However, cultivator can save money for mushroom growing on high-temperature season as like summer in Korea. Since picking individual mushrooms is tedious and often damages the fragile fruiting bodies compared with other species of oyster mushrooms.

  • In order to improve the accuracy of microseismic epicenter location through the inversion techniques using P and S wave first arrivals, field experiments of microseismic monitoring were performed using borehole 3-component geophones. The direction of epicenter was estimated from the hodograms of P-wave first arrivals through the weight drop experiments in which the $\times$ component of 3-component geophone was aligned to the magnetic north. The picking of S wave first arrival was possible in the polarization filtered data even if S waves are difficult to be identified in raw data. The inversion technique using only P wave first arrival times can often converge to the local minimum when the initial values for epicenter are largely apart from the true epicenter, so that the correct solution can not be found. To solve this problem, the epicenter determination method using differences between P and S wave arrival times was used to estimate proper initial values of epicenter. The inversion result using only P-wave first arrival times which started from the estimated initial values showed the improved accuracy of the epicenter location.

  • As a part of studies on the development of a Gugisuen(Lycium chinense M.), which is one of the unutilization of waste resources, we investigated the composition of fatty acid and amino acid according as picking period and varieties of Gugisuen. The chemical components of Gugisuen were as follows : 1. Proximate composition of Gugisuen were Cheongyang native had the highest contents of crude lipid, crude protein, total sugar, and the contents of crude protein, total sugar, and reducing sugar was the highest picked on June 20. 2. The contents of $P_2O_5$, $K_2O$, CaO, MgO, Cu, and Mn were higher in Cheongyang native than that of other varieties. And mineral contents of Gugisuen picked on May 10 were the highest. 3. The major fatty acids were linoleic, linolenic acids, and these unsaturated fatty acids composed about 50% of total fatty acids. Fatty acid compositions between each varieties were not significant, and those components were the highest in Gugisuen picked on May 10. 4. Eighteen amino acids were identified from Gugisuen, glutamic acid, the highest content was $10.05\sim10.94%$ and these contents increased in the order to aspartic acid > glycine > alanine > leucine > lysine. The contents of serine, arginine, methionine, cystine-2 and isoleucine were higher in late harvest time and glutamic acid and tryptophane were higher in early harvest time.

  • With well-being boom recently, the common people, but not experts, are increasingly taking in them directly by picking wild herbs. However, only experts can distinguish between edible vegetables and poisonous herbs from the wild herbs. Especially, it is not even easy for experts to distinguish them only by looking into buds in spring without flowers or fruit. So, sometimes many patients are being carried into the emergency room by the toxic symptom after taking by misunderstanding the poisonous herbs as edible vegetables. For herb intoxication as well as drug intoxication, what kinds of vegetables patients took in, and when and how much they took in them are important information for curing. Of course, in the case of intoxicating in the wild herbs, the patients can have a lot of symptoms and sings-hemodynamic alteration and abnormal neurologic sign as well as gastrointestinal symptoms-according to the kinds of herbs which they took in. Therefore, it is difficult to find the kinds of herbs which they took in through the specific symptoms. Recently we experienced a case with showing typical anticholinergic symptoms after ingestion of Scopolia japonica. As a result, the publicity activities about the wild plants needs because if the person without their previous knowledge take in the poisonous herbs, serious side effects can be produced..

  • The first legislation for terminal health-care decision was California's Natural Death Act (NDA) of 1976 that permitted any adult person to execute a directive directing the withholding or withdrawal of life-sustaining procedures. Advance directive legislation has subsequently progressed on a state-by-state basis. By 1992, all 50 states, as well as the District of Columbia, had passed legislation to legalize some form of advance directive. This state legislation, however, has resulted in an often fragmented, incomplete, and sometimes inconsistent set of rules. Statutes enacted within a state often conflict and conflicts between statutes of different states are common. In an increasingly mobile society where an advance health-care directive given in one state must frequently be implemented in another, there is a need for greater uniformity. In 1993, the Uniform Law Commissioners approved the Uniform Health-Care Decisions Act (UHCDA) in order to bring order to the existing chaos. Unfortunately, the Commissioners waited too long to act. By the time the UHCDA was approved, nearly all states had passed legislation governing advance directives. Consequently, the UHCDA has achieved only a limited success, picking up but one or two enactments a year. The UHCDA is currently in effect in around 10 states: Alabama, Alaska, California, Delaware, Hawaii, Kansas, Maine, Mississippi, New Mexico, Tennessee, Wyoming. In these states the previous laws related to the subjects have been all repealed. The overall objective of the UHCDA is to encourage the making and enforcement of advance health care directives including living will or individual instruction, power of health-care attorney and to provide a means for making health care decisions for those who have failed to plan. The U. S. House of Representatives in 1991 enacted the Patient Self-Determination Act (PSDA). The Act stipulates that all hospitals receiving Medicaid or Medicare reimbursement must ascertain whether patients have or wish to have advance directives. The Patient Self- Determination Act does not create or legalize advance directives; rather it validates their existence in each of the states. Now in America, terminal health-care decision or advance directive for health care is common and universal system. The problem, however, is how to let more people use these good tools to make their lives more beautiful and honorable.

  • The physical properties of mulberry leaf noodle were compared with 3 level of rates(5, 10, and 20%) of mulberry leaf powder to wheat flour and 6 times of leaf picking seasons. The contents of rutin, ${\gamma}$-aminobutyric acid (GABA) and inorganic compounds in mulberry leaf were analyzed with seasons and pretreatment of mulberry leaf. Dry matter content of mulberry leaf powder was about 20%. The leaf powder passed through 100 mesh sieve was 6% from fresh leaf weight. Through the taste test, 10% mulberry powder rate to flour was the best. Rutin content decreased with season, 319mg/100g DW on May 13, but 111mg/100g DW on May 26 and 43mg/100g DW on June 9. Rutin in dry leaf lost 37% by steaming and 83% by in boiling water. CAGA content on leaf decreased with season, 27.7mg/100g FW on May 13 and about 60% of on June 9.

  • The purpose of this study was to examine whether chicken-rearing activity is effective on the character, emotion and self-esteem of middle school students, as a pilot study for the development of an animal-assisted education program based on chicken-rearing activity. School was selected as the place where students have experience with raising animals before and no poultry farms were located near the school. The experimental group consisted of 11 students as the chicken-rearing group. The conducted activities were greeting chickens, cleaning henhouse, feeding them, and picking eggs up for five months. Character, emotion and self-esteem scales were used as test tools, and pre-testing and post-testing were conducted to verify the effectiveness of the study. Data collected were analyzed by using SPSS Win 25.0 statistical program. As a result, the character, emotional stability and self-esteem of middle school students who participated in chicken-rearing activity were improved. This study is meaningful in that the chicken-rearing activity proved to be effective for the character, emotion and self-esteem of middle school students and prepared an experimental case study for developing an animal-assisted education program based on chicken-rearing activity. It is expected to be useful as basic data of animal-assisted education for adolescents in school.

  • A persimmon harvesting vehicle that can be operated in hilly orchards as well as a manipulator that can be used to harvest persimmons located in remote positions in the trees were designed and developed. The vehicle could be operated with keeping balanced position in an inclined field and its working platform could be moved up and down easy to approach fruits in a remote region with the aids of a hydraulic and a electrical and electronics systems. The weight of the vehicle was 927 kg and the center of gravity was located at 427 mm to the inner side from the center of a right driving caterpillar, 607 mm to a rear axle from the center of a front axle, and 562 mm to upward from ground. The automatic level control sensor for leveling the working platform was activated within 14.5 ∼ 16.5 degrees of slope variation. The total length of the manipulator was 1.39 m and weight is 975 g. It was powered by a 12 V geared motor to detach persimmon fruits with a rotational force. The gripper was made of plastic and rubber to increase a frictional force. In a performance evaluation test, static tipping angle, dynamic tipping angle toward front side when the vehicle was moving downward, climbing angle, driving speed of the vehicle were measured or calculated. In persimmon harvesting tests 24.9% of yield was increased by hand picking with the aid of the vehicle and additional 7% of yield were increased when the manipulator was used. Therefore, 99010 of total possible yield was achievable when both of the vehicle and the manipulator were used for the manual persimmon harvesting. Increase in 22.5% of total yield was achieved with the manipulator only.

  • This study empirically conduct structural equivalence analysis based on social network analysis in picking up on overall structural characteristics of technological knowledge exchange in a regional cluster. Previous conceptual studies so far have argued that performance differences among structurally equivalent groups exist. However, because little research has been done to empirically investigate this conceptual hypothesis, this study is conducted as complementary to fill this void. For analysis, we utilize two-mode network data consisted of 2,550 firms by investigating 53 technological knowledge exchange-related associations within Gumi national industrial cluster. The results show that some structurally equivalent groups can be defined appropriately and its role can be conditioned by firms' salient characteristics attached to each structural equivalent groups. In addition, it is presented through the present study that performance difference in structural equivalent groups can be distinct by some selected performance indicators. Finally, this study suggests the need to advance the study of performance differences in structurally equivalent groups in the future.
