  • Purpose: The purpose of this study was to compare muscle activities in the frontal plane and scapular plane of the middle fiber and lower fiber of the trapezius muscle at different shoulder abduction angles. Methods: Twenty male and female students in their 20s participated in this study. Each subject maintained shoulder abduction at $75^{\circ}$, $90^{\circ}$, $125^{\circ}$, and $160^{\circ}$ in a standing position and repeated motions three times each in the frontal plane and the scapular plane. While maintaining the motions for 10 seconds in each posture, surface electromyography (EMG) was used to measure muscle activity of the middle fiber and lower fiber of the trapezius muscle. The collected EMG data were normalized using maximal voluntary isometric contraction (MVIC). Differences in muscle activity of the middle fiber and lower fiber of the trapezius muscles according to the angles at each plane were statistically processed using repeated measured analysis of variance, and an independent t-test was used to examine the differences between the two planes at each angle. Results: Muscle activity of the middle and lower trapezius during shoulder abduction in the frontal plane and scapular plane significantly increased as the angles increased (p<.05). However, muscle activity of the middle trapezius was significantly lower in the scapular plane than in the frontal plane for all shoulder abduction angles (p<.05). Conclusion: The results of this study suggest that during shoulder abduction, angles should be different according to the goals, and for training during an acute phase or early phase for functional recovery, it is more efficient to perform the training in the scapular plane than in the frontal plane.

  • The object of International License Contract is technology. Technology is means to produce visible goods, which are human's intellectual creations such as Intellectual Property Right - patent, design, trademark- and Know-how. Unlike visible goods which decrease as being used, these technologies are possible to be produced expansively and develop additionally. Therefore, the way to make a contract of goods is a sales contract which transfers ownership while technology follows license contract which gives approval of use for a certain period. International license contract means that licensor has right to possess, allows licensee to use licensed technology for a fixed period and takes royalty. So there are various matters such as selection of the duration of a contract, confirmation of technology range, competition limitation, technique guidance and support, calculation of royalty, withholding tax between parties. This study examines licensor's grant of license and competition limitation. Intellectual property rights fundamentally give exclusive rights to the creator so the licensor use or dispose of his or her intellectual property rights at will. Technology transfer is possible through license contract because of this right. But licensor must exercise his or her intellectual property rights within a reasonable limit. It means, when licensor makes an unreasonable demand abusing his or her position, it is regarded as competition limitation clause and the deal itself may become null. Therefore, restraint on competition needs to be examined in detail as it influences on contract validity. Each country has their own competition laws for establishing a fair market order and inspection guide and guideline for judging whether there is any unfair act related to intellectual property rights. Judgment on intellectual property rights is subject the technology-introduced country's domestic laws and thus, contracting parties each need to precede opposite nation's domestic laws system.

  • This study examined the cases of Cheongbaek-ri who were the model of integrity and clean official in Korean tradition, and tried to draw some implications for modern public integrity education. Integrity is a subject and a virtue in itself. Integrity can thus be seen in terms of value education. Cheongbaek-ri in Korean tradition qualifies as modeling in the value education. There were many examples of Cheongbaek-ri in our tradition. This study focused on Park Su-ryang, Lee Won-ik, and Jeong Yak-yong as representatives of each period during Josun Dynasty. Even at the high status, they had not abused their position for self-greed. With less greed, they had been happy even if they had been not rich. They initially tried to be a savior in their daily lives, with their own mind in vain. Their works would be a good example for public officials of modern Korea. In the future, if the educational institutions of the public use this model as a material, it would be very effective.

  • The purpose of this study was to identify the relationship between resilience and organizational socialization in new nurses. Data collection for the study was carried out between September 28th and December 30th, 2012 by surveying 221 new nurses working in general hospitals located in D, K, and P city. Measures were subjects' resiliency and organizational socialization. The data were analyzed using t-test, ANOVA, Person's correlation coefficients and multiple regression analysis with SPSS/WIN 19.0 version. The average of subject's resilience was 3.37(${\pm}0.62$) and organizational socialization 3.20(${\pm}0.70$). There were significant differences in organizational socialization according to age, number of hospital beds, pay grade, desired position and clinical training experiences of hospital. Resilience correlated positively with organizational socialization. Factors affecting new nurses organizational socialization were identified in the order of resilience, clinical training experiences of hospital, age and pay grade. The findings of the study indicate that in order to increase new nurses' organizational socialization, their resilience have to be enhanced.

  • Objective: The aim of this study was to investigate the influence of seat heights for optimizing the ingress/egress performance in the elderly people. Background: Recently elderly users have been increasing in number and the ease of ingress/egress of the vehicle becomes an important issue. Method: Seven elderly subjects participated in this study(age: 71.7${\pm}$3.6yr, height: 167.7${\pm}$5.4cm, weight: 68.1${\pm}$11.5kg). Each subject performed the sitting and rising task from comfortable seated position on the chair under the following conditions: (1) with a lumbar support and (2) without a lumbar support. We measured EMG activities of seven muscles(tibialis anterior, soleus, gastrocnemius, vastus lateralis, rectus femoris, biceps femoris and erector supinae) and ranges of motion in lower limb during sitting and standing from three different heights (400mm, 500mm and 600mm from ground) of slide-up seat. Results: Muscle activities and angular movements of hip and knee joints during standing-up and sitting-down with a high seat height(600mm) were reduced mean 30.4% in extensor muscles, 57.11% in flexor muscle, 18.74% in erector muscle and 31.0% in joints compared with a low seat height(400mm). Conclusion: Muscle activities and joint movements in hip and knee were reduced when rising/sitting from a high seat height(600mm) compared with a low seat height(400mm). Application: This study can be used to design vehicle that are easy to get in and out of by older peoples with or without impairments.

  • $Lokap{\bar{a}}las$ are understood as the deities of four directions in Buddhism: $Dhrtar{\bar{a}}stra$ in the East, $Vir{\bar{u}}dhaka$ in the South, $Vir{\bar{u}}p{\bar{a}}ksa$ in the West and $Vai{\acute{s}}ravana$ in the North respectively. Their common name is, therefore, called as the "Four Guardian Kings", whose function is to prevent demonic forces from entering into its sacred world. Although the position of $Lokap{\bar{a}}las$ is to the lowest level in the hierarchy of the minor deities in Buddhism, the cult of $Lokap{\bar{a}}las$ was widely spread and prominent in the countries of Northern Buddhism. It played a significant role in terms of the state-protecting Buddhism, on behalf of it's esoteric and magic power. More than 20 Gateways of the $Lokap{\bar{a}}las$ and $Lokap{\bar{a}}la$ statues were still well preserved in Korea, and they were believed to be constructed after the Japanese attack in 1592. After war, monks had concentrated on restoring ruined temples and building many new Gateways of the Four Guardian Kings over the Korean peninsular. Under such circumstances, even though the $Lokap{\bar{a}}las$ played a significant role as the subject of cult in Korean Buddhism. they might have a small chance to be taught traditional Lama iconography exactly. The purpose of this essay is to examine the relation of orientation of the Gate way of $Lokap{\bar{a}}las$ and allocation of each Kings inside the gate.

  • Push-up plus has been advocated for increasing the activity of the serratus anterior muscle, the most critical scapular stabilizer. However, no previous study has reported the possibility of compensatory motion on the part of the pectoralis major, which could substitute for the action of the serratus anterior during push-up plus. The aim of the current study was to investigate the immediate effect of electromyography (EMG) biofeedback of the pectoralis major muscle on the pectoralis major, upper trapezius, and serratus anterior muscles during push-up plus. Fourteen healthy young subjects voluntarily participated in this study; each subject performed push-up plus from the quadruped position, in two conditions (i.e., with or without visual and auditory biofeedback). Surface EMG was used to measure pectoralis major, serratus anterior, and upper trapezius activity. A paired t-test was used to determine any statistically significant difference between the two conditions. Additionally, effect size was calculated to quantify the magnitude of EMG biofeedback in each muscle. Visual and auditory feedback reduced pectoralis major muscle activity significantly (p=.000) and increased the serratus anterior muscle activity significantly (p=.002), but did not induce a significant difference in upper trapezius muscle activity (p=.881). Thus, it is concluded that the visual and auditory feedback of pectoralis major muscle activity can be used to facilitate serratus anterior muscle activity during push-up plus.

  • It has been a long time since the cephalometrics was introduced to orthodontic field for diagnosis and treatment planning, but it's main concern was limited to hard, skeletodental tissue. It is well known that perioral and facial soft tissue determine the position of individual teeth and that the abnormality in size and shape of the soft tissue are able to cause malformed occlusion. Because of our lack of knowledge about resultant morphologic changes in the relationship between skeletal pattern and specific pattern of lingual and facial muscles, we can't help setting greater value on only abnormalities of teeth in the skeletal interrelationship. In a point of view that the orthodontist is dealing primarily with muscular structures around the dentition, the tongue, lips, and cheeks, therefore it may be desirable to estimate these structure and their potential influence on the dentition on developmental and time base. The author hit upon on idea of the aspect above, so studied on the intermaxillary space and tongue space and this study used the data from cephalometric films of 33 male and 40 female subject aged from 6 to 11 years of normal Korean children following results were obtained: 1. Means and standard deviation of Korean children were obtained. 2. Yearly increment of each variables were obtained. 3. There is the correlationship more than average among the variables except posterior intermaxillary height item. 4. There are differences between male children and female children in all variables except posterior intermaxillary space item. 5. All variables increased as the age increased except posterior intermaxillary height item of male children.

  • Purpose : To investigate the differences between the position of the mandibular condyles in temporomandibular joints of patients presenting with normal occlusion and skeletal class III malocclusion. Materials and Methods: Forty-two subjects with normal occlusion and thirty-seven subjects exhibiting skeletal class III malocclusion prior to orthodontic treatment were included in the study. Transcranial radiographs of each subject were taken at centric occlusion and 1 inch mouth opening. The positional relationship between the mandibular condyles with articular fossae and articular eminences at two positional states were evaluated and analyzed statistically. Results: The mandibular condyles of the skeletal class III malocclusion group were found to be located more anteriorly from the center of the articular fossae compared to the normal occlusion group in centric occlusion. The mandibular condyles of the skeletal Class III malocclusion group were located more superiorly from the middle of articular height than those of the normal occlusion group in centric occlusion. However, these differences were not statistically significant. At 1 inch mouth opening, the mandibular condyles of the skeletal class III malocclusion group were placed more posteriorly from the articular eminences than those of the normal occlusion group. The mean angle of the articular eminence posterior slope were 56.51 ° ± 6.29° in the normal occlusion group and 60.37° ± 6.26° in the skeletal Class III malocclusion group. Conclusions: The mandibular condyles of the skeletal Class III malocclusion group were placed more anteriorly at centric occlusion and more posteriorly at 1 inch mouth opening when compared with those of the normal occlusion group.
