Wireless sensor networking technology is one of the basic infrastructures for ubiquitous environment. It enables us to gather various sensory data such as temperature, humidity, gas leakage, and speed from the remote sensor devices. To support these networking functions, IEEE WPAN working group makes standards for PHY and MAC, while ZigBee Alliance defines the standards for the network, security, and applications. The low-rate WPAN was emerged to have the characteristics of network resilience, low cost, and low power consumption. It has a broad range of applications including, but not limit to industrial control and monitoring, home automation, disaster forecast and monitoring, health care. In order to provide more intelligent and robust services, users want voice-based solutions to accommodate to low-rate WPAN. In this paper, we have evaluated voice quality of an IEEE 802.15.4 standard compliant voice node. Specifically, it includes the design of a voice node and experiments based on the prediction of voice quality using the E-model suggested by ITU-T G.107, and the network communication mechanisms considering beacon-enabled and nonbeacon-enabled networks for real-time voice communications.

The current study examined the effects of socio-demographic characteristics and peer relations on the emotional, behavioral, and comorbid disorder symptoms among low-low-SES children, using the Young Lives Survey: an International Study of Childhood Poverty: Round 1, 2002. Participants were 1,000 8-year-old children (502 boys and 498 girls) from low-low-SES families. Data were analyzed using ANOVA, t-tests, post hoc test (Scheffe's method), correlations, and multiple logistic regression analyses according to the analysis strategy. There was a moderate correlation between selected socio-demographic variables and emotional/behavioral disorder symptoms, and the caregiver's marital status, child's health compared to others, child's work status corresponded to significant differences in their emotional/behavior levels. Regarding the logistic regression analysis, in addition to the effects of socio-demographic variables reflecting the characteristics of less-developed countries, marital status, child's working status, and conflicts with peers proved to be detrimental to emotional, behavioral, or comorbid disorder symptoms in low-SES children, who have been lack quality parenting, social resources, and child human rights. Results indicated the need to develop health care services that would address those problems and appropriate intervention and prevention programs targeting children in low-income families. Moreover, careful assessment and intervention for child's health status, child's working status and peer relationship problems are suggested as possible strategies for helping children at risk of exhibiting further problematic behaviors.

The mobile medical service has been operated for many years by a number of medical schools and hospitals as a most convenient means of medical service delivery to the people residing in such area where the geographical and socioeconomic conditions are not good enough to enjoy modern medical care. Despite of official appraisal showing off simply with numbers of outpatients treated and medical persons participated, however, as well recognized, the capability (in respect of budget, equipment and time) of those mobile medical teams is so limitted that it often discourages the recipients as well as medical participants themselves. In the midst of rising need to secure medical service of good quality to all parts of the country, and of developing concept of primary health care system, authors evaluated the effectiveness of and problems associated with mobile medical servies program through the community diagnosis of a village (Opo-myun, Kwangju-gun) to obtain the information which may be halpful for future improvement. 1. Owing to the nationwide Sae-Maul movement powerfully practiced during last several years, living environment of farm villages generally and remarkably improved including houses, water supply and wastes disposal etc. Neverthless, due to limitations in budget time and lack of knowledge (probably the most important), these improvements tend to keep up appearances only and are far from the goal which may being practical benefit in promoting the health of the community. 2. As a result of intensive population policy led by the government since 1962, there has been considerable advances in understanding and the rate of practicing family planning through out the villages and yet, one should see many things, especially education, to be done. Fifty eight per cent of mothers have not received prenatal check and the care for most (72%) delivery was offered by laymen at home. 3. Approximately seven per cent of the population was reported to have chronic illness but since only a few (practically none) of the people has had physical check up by doctors, the actual prevalence of chronic diseases may reach many times of the reported. The same fact was observed also in prevalence of tuberculosis; the patients registered at local health center totaled 31 comprising only 0.51% while the numbers in two neighboring villages (designated as demonstration area of tuberculosis control and mass examination was done recently) were 3.5 and 4.0% respectively. Prevalence rate of all dieseses and injuries expereinced during one month (July, 1977) was 15.8%. Only one tenth of those patients received treatment by physicians and one fifth was not treated at all. The situation was worse as for the chronic patients; 84% of all cases either have never been treated or discontinued therapy, and the main reasons were known to be financial difficulty and ignorance or indifference. 4. Among the patients treated by our mobile clinic, one third was chronic cases and 45% of all patients, by the opinion of doctors attended, were those who may be treated by specially trained nurses or other paramedics (objects of primary care). Besides, 20% of the cases required professional managements of level beyond the mobile team's capability and in this sense one may conclude that the effectiveness (performance) of present mobile medical team is quite limitted. According to above findings, the authors would like to suggest following for mobile medical service and overall medicare program for the people living in remote country side. 1. Establishment of primary health care system secured with effective communication and evacuation (between villages and local medical center) measures. 2. Nationwide enforcement of medical insurance system. 3. Simple outpatient care which now constitutes the main part of the most mobile medical services should largely be yielded up to primary health care unit of the village and the mobile team itself should be assigned on new and more urgent missions such as mass screening health examination of the villagers, health education with modern and effective audiovisual aids, professional training and consultant services for the primary health care organization.

This study is aimed at providing basic information necessary to set up education program and strategies to prevent high school students from smoking by school health care service. The main groups of study are 814 third-grade male students, 557 parents and 362 teachers, who were randomly chosen at 8 high schools in Seoul. Date analysis consisted of Chi-square test and percentage. The findings of the study are as follows: 1. The less interesting family life is, the more increasing current smoking rate is, (ex-smoking rate 53.5%, re-smoking rate 40.3%, current smoking rate 24.3%) 2. According th the results of $x^2$-test for the school life and the smoking, the students above ranking 41 showed th increase as 48.7% for continuous smoking, 18.9% for re-smoking, 67.6% for the present smoker. But it turned out that the students belonged to ranking 10 were not experienced the smoking. So it showed that there was a correlation between score and smoking. 3. It is noted that 93.3% of students, 93.3% of parents and 96.1% of teachers recognize harmful effect of smoking. But less than 70% those have recognized only half of all smoking knowledge. 4. There is a significant difference in the contends and types of education between parents and teachers. 5. For the time of home education and school health education to prevent the smoking, it turned out that 44.9% of students, 42.4% of parents, and 47.4% of teachers considered the optimal time as a high school' days. In addition it appeared that 40.5% of students, 33.4% of parents, and 54.6% of teachers recognized the necessity of the early education before the elementart school. For the optimal time to begin school health education, it showed that the middle school days were indicated from 56.6% of students, 52.7% of parents, the elementary school days were 54.6% of parents, the elementary school days were 54.6% of teachers.

The purpose of this study is to investigate differences in initial patient states based on types of burn accidents in the pre-hospital stage. 1,223 items of transfer data from burn accidents of Gyeonggi-do emergency medical services in 2013 were used. Burn accidents were most common in children younger than 10 years old (26.0%) and happened mostly at home (51.3%). Patient states by burn type were stable on average, but burns by electricity showed 10.7% of awareness condition U (Unresponsive), which was higher than that of the other burn types. Initial patient states for this type were shown to be serious, unlike other burn types, with temperatures of $35.90^{\circ}C$ and third degree burn depth (39.28%). Understanding initial patient states based on burn type is necessary in order to do effective approach in the pre-hospital stage.

As emergence of the ubiquitous society, it is possible to access the network for services needed to us in anytime and anywhere. The phenomena has been accelerated by revitalization of the sensor network offering the sensing information and data. Currently, sensor network contributes the convenience for various services such as environment monitoring, health care and home automation. However, sensor network has a weak point compared to traditional network, which is easily exposed to attacker. For this reason, messages communicated over the sensor network, are encrypted with symmetric key and transmitted. A number of symmetric cryptography algorithms have been researched. Among of them HIGHT algorithm in hardware and software implementation are more efficient than tradition AES in terms of speed and chip size. Therefore, it is suitable to resource constrained devices including RFID tag, Sensor node and Smart card. In the paper, we present the optimized software implementation on the ultra-light symmetric cryptography algorithm, HIGHT.

This study was uncertaken to find an effective management modality for patients with hypertension. Patients 60years or older were selected for this purpose from a general hospital and a welfare center in Pusan and from a public health clinic in Cheju Island. During the month of October in 1984. the management modality for hypertension. the incurred medical expenses. and knowledge about the hypertension were analyzed and compared. The following results were obtained: 1. The a erage total medical expense per year was highest at the general hospital followed by the public health clinic and the welfare center. 2. It was found that the patients chose the public health clinic for its low medical cost. the welfare center for its proximity as well as for its low medical cost. and the general hospital for its quality medical services Also. the study has shown that the prescription of drugs was the major service provided by the public health clinic whereas the blood pressure measurement. the prescription of drugs. and family planning were the primary service offered by the welfare center. Drug prescription and blood pressure measurement were two of the most important services by the general hospital. 3. It was shown that the knowledge of hypertension was highnest at the welfare center whereas the management of hypertension was highest at the public health clinic. Based on above results and considering the chronic nature. it is believed that family awareness of the illness was one of the most important aspects for effective management of the hypertension for the elderly patients. In addition. the health care clinics at every level should come forward to execition of the educational programs and home nursing schomes for the effective management of the hypertension patients.
