Purpose: The purpose of this study was to develop family support oriented physical activity program for the male elderly with sarcopenia based on social cognitive theory. Methods: This program was developed through an analysis of 18 related intervention literatures, results of a focus group interview with 5 elderly men with sarcopenia and the content validity index of the program content adequacy and applicability by 6 experts. The combined exercise with resistance exercise and aerobic exercise was constructed in accordance with the recommendations of the American College of Sports Medicine (ACSM) and experts' opinions. Results: The program consists group education sessions (5 times, 60 minutes for each) for 12 weeks and family support oriented physical activity program composed of individual intervention (sending alarm for physical activity for 10 times and telephone monitoring for 2 times). The program also reflects the concept of self-efficacy and self-regulation, which are important factors for continuing physical activity through family support. The progressive resistance exercise was developed by composing 5-6 systemic movement forms that repeat 2-3 days a week and 2-5 sets at least. Conclusion: It is proposed to standardize the family support oriented physical activity program through the further studies so that the program can be utilized for the various groups of people who need increased level of physical activities.

The purpose of this study was to investigate the single-person household's demand for a wearable healthcare system that provides the ischemic heart disease and cardiopulmonary alarm to be developed. In this study, in-depth interviews were conducted with six unmarried individuals in their thirties who were in the workplace and the results were interpreted by Giorgi's phenomenological analysis method. The study results indicated that although the wearable healthcare system was implemented with high-technology functions that serve the intended purpose, it is necessary to comprehensively consider factors such as aesthetics, comfort, and ease of washing. In this study, we found that the variables influencing the interviewees' intent to accept healthcare services are complex and cannot be attributed to one factor alone; this study has also shown a variety of interpersonal correlations. In addition, although health-care research focusing on the elderly has been conducted in the past, it is suggested that younger generations such as those in their thirties can also be studied as health care service adopters.

Objectives: The gastric ulcer is a common disorder of the stomach and duodenum. The basic physiopathology of a gastric ulcer results from an imbalance between some endogenous aggressive and cytoprotective factors. This study examined whether Ganoderma lucidum pharmacopuncture (GLP) would provide protection against acute gastric ulcers in rats. Methods: Sprague-Dawley rats were divided randomly into 4 groups of 8 rats each: normal, control, normal saline (NP) and GLP groups. The experimental acute gastric ulcer was induced by using an EtOH/HCl solution and the normal group received the same amount of normal saline instead of ethanol. The NP and the GLP groups were treated once with injections of saline and GLP, respectively. Two local acupoints were used: CV12 (中脘) which is the alarm point of the Stomach Meridian, and ST36 (足三里), which is the sea point of the Stomach Meridian. The stomachs from the rats in each group were collected and analyzed for gross appearance and histology. Also, immunohistochemistry staining for BAX, Bcl-2 and TGF-${\beta}1$ was performed. Results: Histological observations of the gastric lesions in the control group showed comparatively extensive damage of the gastric mucosa and necrotic lesions had penetrated deeply into the mucosa. The lesions were long, hemorrhagic, and confined to the glandular portions. The lesions were measured microscopically by using the clear depth of penetration into the gastric mucosal surface. The length and the width of the ulcer were measured and the inhibition percentage was calculated. Wound healing of the acute gastric ulcer was promoted by using GLP, and significant alterations of indices in gastric mucosa were observed. Such protection was shown by gross appearance, histology and immunohistochemistry staining for BAX, Bcl-2 and TGF-${\beta}1$. Conclusion: These results suggest that GLP administered at CV12 and ST36 can provide significant protection to the gastric mucosa against an ethanol-induced acute gastric ulcer.

The emergence of biofilms have generated urgent alarm in clinical and medicine manufacturing fields engaged in the search for novel antimicrobials from ethno-medicinal plants. The National Institutes of Health (NIH) has estimated that 70% of all microbial infections in the world are associated with biofilms. In addition, the emergence of strains resistant to conventional antibiotics has become a serious threat to global public health. Therefore, finding alternative medicines is a major issue in the field of integrative medicine. In this study, four different herb extracts were screened for biofilm formation and the activities of Klebsiella pneumoniae. Of them, Scutellaria scordifolia Fisch. ex Schrank extracts had inhibitory effects on bacterial growth and biofilm formation. The Scutellaia scordifolia Fisch. ex Schrank extracts did not cause any cytotoxicity to L929 cells. The growth of K. pneumoniae was inhibited compared to other comparators in the experimental group containing Scutellaia scordifolia Fisch. ex Schrank. In a group of experiments with plant extracts, a maximum of 60 times the level of living bacteria was confirmed compared to the controls without the addition of the Scutellaia scordifolia Fisch. ex Schrank extracts. In a group of experiments with a significantly lower level of fluorescence extraction, differential interference contrast imaging showed that the number of K. pneumonae was reduced. These results suggest that extracts of this plant be applied as antimicrobial agents against K. pneumoniae, particularly in biofilm forms.

Objective : To investigate the relation to the organs, shu points and mu points. The labeled common locations of the spinal cord and brain were observed following injection of pseudorabies virus(PRV) into the the kidney, UB23 and GB25. Methods : After survival times of 96 hours following injection of PRV, The fifteen rats were perfused, and their spinal cord and brain were frozen sectioned($30{\mu}m$). These sections were stained by PRV immunohistochemical staining method, and observed with light microscope. Results : In spinal cord, PRV labeled neurons projecting to the kidney, BL23 and GB25 were founded in cervical, thoracic, lumbar and sacral spinal segments. Dense labeled areas of cervical segments were overlap in lateral cervical n. and lamina III-V area. Thoracic segments were overlap in lateral spinal n., intermediolateral n. and lamina V-X areas. Lumbar segments were overlap in lamina I-V areas. Sacral segments were overlap in lamina IV, V and X areas. In brain, PRV labeled areas projecting to the kidney, UB23 and GB25 were overlap in the A1 noradrenalin cells/C1 adrenalin cells/caudoventrolateral reticular n./rostroventrolaterai n., raphe obscurus n,, raphe pallidus n., raphe magnus n., gigantocellular reticular n., locus coeruleus, subcoeruleus n., A5 cell group and paraventricular hypothalamic n.. Conclusions : This results suggest that PRV labeled overlap areas of projecting to the kidney may be correlated to shu and mu points related to the kidney. These morphological results provide that organs-shu(transport) and mu(alarm) points interrelationship may be related to the central autonomic pathways.

The system design and the system performance analysis of 3D imaging laser radar system for the mapping purpose is addressed in this article. For the mapping, a push-bloom scanning method is utilized. The pulsed fiber laser with high pulse energy and high pulse repetition rate is used for the light source of laser radar system. The high sensitive linear mode InGaAs avalanche photo-diode is used for the laser receiver module. The time-of-flight of laser pulse from the laser to the receiver is calculated by using high speed FPGA based signal processing board. To reduce the walk error of laser pulse regardless of the intensity differences between pulses, the time of flight is measured from peak to peak of laser pulses. To get 3D image with a single pixel detector, Risley scanner which stirs the laser beam in an ellipsoidal pattern is used. The system laser energy budget characteristics is modeled using LADAR equation, from which the system performances such as the pulse detection probability, false alarm and etc. are analyzed and predicted. The test results of the system performances are acquired and compared with the predicted system performance. According to test results, all the system requirements are satisfied. The 3D image which was acquired by using the laser radar system is also presented in this article.

Objectives : The aim of this study was to examine the developmental and clinical characteristics associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed a parent questionnaire consisting of a Child Behavior Checklist(CBCL). Data related to the prenatal, perinatal and developmental history, past and current medical history were collected. Ninety-three normal students were selected as the control group. Results : The nocturnal enuresis group attained diurnal and nocturnal urinary control significantly later than those in the normal control group.49.2% of the children with nocturnal enuresis had the family history of nocturnal enuresis. Daytime incontinence was present in 41.3% of the nocturnal enuresis group. The percentages of sleep-related disturbances were significantly higher in the nocturnal enuresis group when compared to the normal control group.42.6% of the children with nocturnal enuresis experienced pharmacotherapy, and 0.4% experienced enuresis alarms. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have a high genetic load and a possibility of developmental delay, which supports the neurodevelopmental point of view with regard to the etiology of nocturnal enuresis. The physicians in Korea prefer pharmacological interventions to alarm interventions in treating Korean children with nocturnal enuresis.

The Tactical Internet(TI) managed by Infantry Brigades is used for the purpose of sharing information of Command Control and Situation Awareness. When there are more than two destinations to transmit data in the TI system, a multicasting is utilized based on pre-defined multicast groups. However even in the case when a source node needs to send some messages like weathercast and attack alarm etc to only a part of Battalion or Brigades in a specific geographical region (destination region), the current TI multicasting protocol is designed to transmit the messages to the pre-defined group or all of the Battalion/Brigade nodes, resulting in inefficiency in terms of end-to-end delay and overhead. In this paper, we propose more efficient protocol for such cases, named as "Tactical Internet Geocasting (TIG)". The proposed scheme firstly checks whether the destination region belongs to one Battalion region or more than two Battalion regions using location information, and then performs a greedy forwarding from the source node to the destination region, followed by a local flooding inside of the destination region. With performance analysis and simulations using NS-2, TIG is compared to the current TI multicasting protocol (i.e., Simplified MDP) and the LBM (Location-based Multicast). The simulation results show that the proposed TIG is more efficient than both in terms of delay and network overhead.
