In an attempt to observe the to long-term training effects, the exercise of rope-skipping was regularly loaded to nine soldiers for nine weeks. And some physical characteristics, cardiopulinonary functions. some blood constituents were measured before, during and after the load of test exercise. treadmill running, and were compared with the pre-trained values. The results obtained were as follows: 1) Body weight, body surface area, skinfold thickness and total body fat decreased sifnificantly after the training. 2) The post-trained values of MVV and $FEF_{25%}$, increased significantly. 3) By the training, heart rates decreased very significantly in the resting, exercising and recovery periods. 4) After the training, the systolic blood pressures of the resting and recovery periods decreased meaningfully, while diastolic blood pressures increased significantly through the recovery stages. 5) In spite of the training, the respiration rates never change in both the resting and the recovery periods. 6) After the training, total cholesterol concentration of the venous blood decreased significantly in the resting the early recovery phases while the blood levels of glucose and HDL-cholesterol decreased very slightly. 7) Blood lactate concentration decreased through the recovery periods and the value of the recovery 20 and 60 minutes decreased obviously, in comparison with the pre-trained values. The above results suggest that the 9 week-training of the rope-skipping brings about the decrease of the body fat contents, the enhancement of cardiopulmonary functions and some changes in the blood constituents.

The recent domestic toy market is filled with the fever of 'Turning Mecard' produced as a character product of units showing in . The toy market of the domestic character licensing industry has shown such rapidly changing trends during the period of broadcasting contents like animation or special films targeting children. Through these contents, the characters are cognized, and also the immersion and loyalty can be increased depending on the progress of the story, on top of marketing effect while the animation is broadcasted. This effect is called gamification meaning that consumers voluntarily participate in the contents after receiving fun. Through the purchase of character products, the immersion and loyalty participate in the animation. Thus, this study analyzed the gamification elements by examining the animation and toy products of currently gaining popularity in the toy market. In the results of the study, the story structure of has the sustainment just like game, which is connected to its character product. Therefore, the users who have watched build up the relationship with each other, and the competition and reward can be done through the game using the character products, which is connected to such high immersion and loyalty.

Due to the change from small volume production to small quantity batch production systems, individual companies have been attempting to produce a wide range of operating strategies, maximize their productivity, and minimize their WIP level by operating with the proper cycle time to defend their market share. In particular, using a complex workflow and process sequence in the manufacturing line has some drawbacks when it comes to designing the production strategy by applying analytical models, such as mathematical models and queueing theory. For this purpose, this paper uses three heuristic algorithms to solve the job release problem at the bottleneck workstation, product mix problem in multi-purpose machine(s), and batch size and sequence in batch machine(s). To verify the effectiveness of the proposed methods, a simulation analysis was performed. The experimental results demonstrated that the combined application of the proposed methods showed positive effects on the reduction of the cycle time and WIP level, and improvement of the throughput.

The purpose of this study was to identify the effects of death education on attitudes toward death and depression for older adults. A death education program consisted of needs of death education, alternatives for dignity on death, not ending death(I, II), hospice(I, II), and 9 patterns of death(I, II, III). Participants in this study were 38 older adults aged 60 years or older. Attitudes toward death and depression scales for Korean elders were employed. The data collection and intervention were performed from January to June, 2008. The subjects participated in a death education program for 1 time per week during 10 weeks. The data were analyzed with t-test, and Pearson correlation coefficients with SPSS/Window 14.0. After the intervention, the subjects showed significant difference in attitudes toward death compared to that of pre-intervention. The subjects after the intervention showed no statistical differences in change of depression compared to that of pre-intervention. Also, attitudes toward death were negatively related with depression both before and after interventions, but the change of relation was not significant. The findings of this study contributed to extend the base of program developments on death education enhancing attitudes toward death among Korean older adults.

The purpose of this study was to investigate the effect of neuromuscular electrical stimulation (NMES) and transcutaneous electrical nerve stimulation (TENS) on muscular strength, pain, range of motion and fear-avoidance in anterior cruciate ligament reconstruction (ACLR) patients. The subjects of this study who received ACLR after arthroscopic injury were divided into two groups: NMES (n=14) and TENS (n=14). Each group received intervention after routine physical therapy. Each electrotherapy intervention was applied regularly for a total of 12 times, 3 times a day (30 minutes) for 4 weeks. The evaluation by intervention method included isokinetic muscle strength in flexion and extension of the knee joint, pain, range of motion of the knee joint, and fear-avoidance beliefs. The results showed significant improvement in pain, range of motion, and fear-avoidance beliefs in both groups (p<0.05). However, there was a significant improvement in isokinetic knee flexion and extension strength only in the NMES group (p<0.05). There was no significant difference between the two electrotherapy methods in muscle strength, pain, range of motion, and fear-avoidance beliefs. These study results suggest that NMES and TENS can be effective intervention methods for pain, range of motion, and fear-avoidance response in patients with ACLR, but to improve muscle strength NMES may be more effective.

In order to investigate the structure and dynamics of atatic poly (vinyl alcohol) (PVA)/water system, laser light scattering experiment has been done in the semi-dilute concentration regime at $25^{\circ}C$. The scattering intensity I(q) can be analyzed with the fractal equation of $I(q){\sim}q^{-m}$ instead of Onstein-Zernike type equation. The fractal dimensionality m was found to be constant after reaching the plateau value of $m=2.6{\pm}0.3$ above C=3wt%. The time correlation function of dynamic light scattering has always two different modes such as fast mode and slow one. The cooperative diffusion of fast mode showed concentration independence contrary 4o the reptation theory's concentration dependent exponent of 3/4. The slow mode can be interpreted as the motion of large scale heterogeneities and its strong concentration dependence is apparent with a large negative exponent of -3.0. It is considered that the stereo-regular arrangement with four successive meso units of -OH plays as a key role in forming such heterogeneity.

Although traffic information has been actively analyzed using big data, it has not been used as much with the consideration of driver characteristics. Among the various types of information, road signs can directly affect the driver. Road signs must provide the optimal information that enables drivers to reach their destinations with ease as well as information suitable for navigation systems. However, present road sign rules provide standardized information, regardless of the road type or size. This study suggests a method for providing road information that will help drivers determine their behavior. First, the minimum character size that can be used on a road sign for each design speed was obtained with respect to the visibility and decipherability of a road sign. Instead of conventional diagram-based direction guidance, a scenario using split-based direction guidance was created. To verify the effectiveness of the provided information, a three-dimensional simulated road environment was constructed, and a driving simulator was used for the test. At a simple plane intersection, the driver was not greatly influenced by directional guidance, but at a complex, three-dimensional intersection, the driver preferred summary-based directional guidance, which is instinctive guidance, over diagram-based guidance. On the basis of the test results, a secondary verification test that applied split-based guidance at a three-dimensional intersection confirmed that the driver had no problems in making decisions.
