Education will be undergoing major changes with the 4th industrial revolution. As education contents will be important in future smart home service, in-depth interviews were conducted against experts and analyzed by the grounded theory approach. Eleven categories emerged through the analysis. In order for educational content to be utilized in smart home services, value creation (central phenomenon) seems to be most critical with preceding overcome of hamlet syndrome. Diversity of content and connectivity (context) should be ensured, and studies that could enhance user experience (intermediary situations) should be conducted and reflected in the content curation and realtime response (interaction strategy). As a result, it can be inferred that the education content service can be expanded in smart home services while satisfying self-development desire of individuals through these processes. Additional selective coding revealed four immediate need area: self-development, home-improvement, health care, and mindful healing.

The purpose of this study was to evaluate the effect of dexamethasone on the healing aspect of gingiva and alveolar bone after extraction. Extracted socket of 24 Sprague-Dawley rat was used. To extract easily and minimize injury, ${\beta}-APN$ 0.2g/kg/day soluted in mineral water was administrated for 5 days before extraction in both group. Ampicillin 1.5ml/kg i.m.,q.d, was administered for preventing infection after teeth extraction in both group, and dexamethasone 0.2mg/kg/day was injected for 3 days in experimental group.3 rats on each day was sacrificed on 1, 3, 7, 15 days after extraction. Histologic examination and the activity of osteoclasts by tartrate resistant acid phosphatase was observed. The results were as follows : 1. The Overall healing pattern was similar with both the experimental and control group, but in experimental group osseous healing was delayed. 2. The activity of osteoclasts was increased to day 3 and then decreased after day 3 in the experimental group. In comparison to the control group, the experimental group showed increased appearance to day 7 and then decreased appearance following day. 3. Regarding to the change of osseous tissue, the activity of osteoblasts was shown at day 7,but osteoclastic activity of the experimental group was less than that of the control group. The osteoclastic activity was statistically significant between two groups except day 7(p<0.05, p<0.01). In conclusion, the effects of dexamethasone for healing of extraction socket were considered as limiting the activity of osteoclasts, and the healing of extraction socket was delayed.

Hereditary peripheral neuropathies can be categorized as hereditary motor and sensory neuropathies (HMSN), hereditary motor neuropathies (HMN), and hereditary sensory neuropathies (HSN). HMSN, HMN, and HSN are further subdivided into several subtypes. Here, we review the most recent findings in the molecular diagnosis and therapeutic strategy for hereditary peripheral neuropathies. The products of genes associated with hereditary peripheral neuropathy phenotypes are important for neuronal structure maintenance, axonal transport, nerve signal transduction, and functions related to the cellular integrity. Identifying the molecular basis of hereditary peripheral neuropathy and studying the relevant genes and their functions is important to understand the pathophysiological mechanisms of these neurodegenerative disorders, as well as the processes involved in the normal development and function of the peripheral nervous system. These advances and the better understanding of the pathogenesis of peripheral neuropathies represent a challenge for the diagnoses and managements of hereditary peripheral neuropathy patients in developing future supportive and curative therapies.

The purpose of the study is to investigate the effectiveness of the concurrent thermotherapy and intermittent fasting therapy for obesity. The experimental therapy conducted at the same time for 11 days, and had 35 adult participants. Six variables(girth, body weight, body mass index, body fat ratio, abdominal fat, and body basal metabolic rate) of participants were measured initially before the experimental therapy, and respectively after two consecutive experimental therapies (S1 and S2). The differences between the averages of the six variables in the initial measurement (C group), S1 group, and S2 group are significant and correlate each other. The differences between variables also were significant within groups and between groups. Additionally, the results show that the effectiveness of the therapy was greater after the 2nd therapy than the 1st therapy. In conclusion, these findings suggest that the concurrent therapy is effective and useful as a natural healing therapy for obesity.

Using raw data of the 'Family income and expenditure survey,' we find that the earning distribution worsened in Korea after the financial crisis; the gap between ninetieth and tenth percentile grew larger after the crisis more than before. Such a phenomenon is apparent within narrowly defined education and labor market experience variables. We found that the increase in earning inequality came from the rapidly increasing return to the components of skill other than the schooling and experience, which is caused by the increasing demand of skill after the crisis. Therefore, we can interpret the growing demand for skill is an important factor leading the increase in the earning inequality after the Crisis. And then, we think that the reason for the increasing demand for skill after the crisis can be found in the changes of the technology, the organizational and personnel practice, the globalization, and the labor market. We can derive policy implications from this : To narrow the inequality we must invest the industrial demand-oriented education.

To confirm the effect of electroacupuncture on the regeneration of injured peripheral nerve, the change of evoked potential in the sciatic nerve, the change of enzyme activity in the spinal cord, and morphological change of injured sciatic nerve were examined comparatively in acupuncture group (AG) and control group (CG) after sciatic nerve of guinea pig was injured by purpose. The value of evoked potential after injury of the sciatic nerve was increased in both AG and CG, but the increase rate of that was higher in AG than CG. Acid phosphatase activity of the spinal cord was increased in 1CG and 2AG, but shown are tendency to return to the normal state as time went by. Ultrastructural recovering rate of the injured sciatic nerve was higher in AG than CG. Also, there was developed only adipose tissue in sciatic nerve of AG. As mentioned above, the effect of electroacupuncture on the regeneration of injured peripheral nerve was confirmed experimentally by change of evoked potential, acid phosphatase and ultrastructure. Especially, the effect of electroacupuncture was appeared clearly in an early stage than other treatment stages.

Ion shower doping with a main ion source of $P_2H_x$ using a source gas mixture of $PH_3/H_2$ was conducted on excimer-laser-annealed (ELA) poly-Si.The crystallinity of the as-implanted samples was measured using a UV-transmittance. The measured value using UV-transmittance was found to correlate well with the one measured using Raman Spectroscopy. The sheet resistance decreases as the acceleration voltage increases from 1kV to 15kV at the moderate doping conditions. It, however, increases as the acceleration voltage increases under the severe doping conditions. The reduction in carrier concentration due to electron trapping at uncured damage after activation annealing seems to be responsible for the rise in sheet resistance. Three different annealing methods were investigated in terms of dopant-activation and damage-recovery, such as furnace annealing, excimer laser annealing, and rapid thermal annealing, respectively.

The aim of this paper is to expound upon the concept of mental health and disease in Plato. In ancient Greece, philosophy was to care for the health of the soul and to pursue the happiness of the life, while medicine was to care for the health of the body. It is the role of philosophy that defines what the mental disease is, rather than the realm of medicine, and the practical function of philosophy is the life of caring for our souls. In order to take care of the soul, it is important to diagnose what the mental disease is and where it comes from. In ancient Greek, medicine disease was initially regarded as a divine punishment and healing as, quite literally, a gift from the gods. Plato, however, insists that mental illness is not just brain problem but a human whole problem, (2) it is caused by imbalance and discord, and (3) ignorance is also a mental disease, (4) and furthermore, injustice and vice are mental diseases as well. Therefore Plato argues that the aim of philosophy is to practice a virtue as the mental health and further to achieve political justice to maintain the health of the soul.

The purpose of this study was to show that yoga psychology aims to actualize the positive potentials in the depth of human mind with the perspective of body-emotion-mind-spirit integration. This approach is described in the context of modern positive psychology. For this purpose, the Self-realization of yoga psychology is discussed, which is to develop one's higher self as a center of psyche apart from one's psychological growth or maturation. An individual can experience positive emotions such as pleasure, joy, happiness and ecstasy through the typical yoga technique of concentration. Happiness is one of the main issues of positive psychology, but yoga psychology called it "ānanda" and divided it further into seven types. The positive emotions of positive psychology seem to be equivalent to positive states of mind in yoga psychology. But yoga regards calmness, tranquility, nonattachment and transcendence as the most valuable virtues for the full actualization of human potentials. From the perspective of yoga psychology, the tranquil state of mind is the wonderful fruit of long and arduous yoga practices. It is the calm and neutral state of mind which is free from all the turmoils of everyday life. Tranquility is beyond the scope of modern positive psychology's issues, but it offers some precious insights to them.

This paper investigates protocol architecture of a Web-ZigBee gateway for interconnecting TCP/IP-based networks and ZigBee/IEEE802.15.4-based wireless sensor networks. The Web-ZigBee gateway delivers data between the TCP/IP network and the ZigBee network. Since those two networks have different communication protocols, a protocol translation mechanism is needed. Herein, we propose a method to deliver query messages from the Internet to the sensor network and receive data from sensors. The protocol translation is performed in the translation layer that is placed above the two application layers, i.e., the Internet application layer and ZigBee application layer. Among various interfaces, we use CGI programming to take care of translation functions efficiently. The CGI manages query information from a client on the Internet and data from the ZigBee sensor network. Whereas the TCP/IP enabled sensor network overlays two heterogeneous communication protocols, overlaying layers increase the complexity and cost of implementing the sensor network. On the contrary, the sensors in our gateway-based system are not only light (because each communication protocol works independently without overlaying), but also efficient because the translation layer mostly alleviates header overloading.
