A retrospective analysis was undertaken for 22 patients with early glottic cancer ($T_1N_0M_0$; 17, $T_2N_0M_0$; 5) who completed curative radiotherapy at the Department of Therapeutic Radiology, Chonnam University Hospital between November 1985 and December 1990. Median follow-up period was 39 months. The 3 year actuarial survival rate of T1, T2 was $81\%$ and $80\%$. respectively. Three patients ($13\%$) showed second malignant tumors and the site of the new primary was esophagus in two patients and lung in the other one. They were excluded from the local control analysis. The local control rate of T1. T2 group was $66\%$ and $50\%$. respectively. The surgical salvage rate and the ultimate local control rate of T1 group was $80\%$ (4/5) and $93\%$. and that of T2 group was $100\%\;(2/2)\;and\;75\%$. respectively. The local control rates of T1 stage were evaluated according to the various parameters. The local control rate of the superficial and exophytic lesion was better than that of the ulcerative and infiltrative one, and the involvement of anterior commissure was not seemed to be adverse prognostic factor. But the protracted treatment time showed the adverse effect on the local control of the disease. All of the eleven patients controlled by primary radiation therapy have maintained their voice well without any significant complication.

The present study was conducted in order to investigate the role of yeast-like fungi in bovine mastitis. Attempts were made to isolate and identify yeast-like fungi from the milk from normal udders and those with clinical or subclinical mastitis and from feces. Also incuded in the study were trials for the pathogenicity of the isolates for laboratory animals and efficacy of an anti-fungal drug for the treatment of mastitis. A total of 133 isolates of yeast-like fungi was made from milk and feces and they were identified as Candida (C.) albicans (5 isolates), C. krusei (63 isolates), C. tropicalis (27 isolates), Torulopsis (T.) glabrata (10 isolates), Rhodotourla sp. (6 isolates), Hansenula sp. (6 isolates) and Pichia sp. (1 isolate). Sixty seven strains of yeast-like fungi were isolated from the milk of 64 quarters (4.3% of quarters examined) of 55 cows (14.3% of cows examined). C. krusei, C. tropicalis, C. pseudotropicalis, C. parapsilosis and T. glabrata were isolated as the causative agents from 20 quarters (1.3% of quarters examined) with clinical mastitis. C. krusei, C. tropicalis, C. albicans, C. pseudotropicalis, T. glabrata, Rhodotorula sp. and Hansenula sp. were isolated as the causative agents from 22 quarters (1.5% quarters examined) with subclinical mastitis. C. tropicalis, C. krusei, T. glabrata and Rhodotorula sp. were isolated as the contaminants from 22 normal quarters (1.5% of quarters examined). C. krusei, C albicans, C. tropicalis, C. pseudotropicalis, C. parapsilosis, T. glabrata, Hansenula sp., Rhodotorula sp. and Pichia sp. were isolated as the contaminants from feces and all of the species except Pichia sp. were isolated from milk of the same cows at the some time. Intramammary infusion of nystatin was effective for the treatment of mastitis caused by C. albicans, C. krusei, C. tropicalis, C. pseudotoropicalis, C. parapsilosis, T. glabrata and Rhodotorula sp. C. albicans, C. krusei, C. tropicalis, C. pseudotropicalis, T. glabrata, Hamsenula sp. and Pichia sp. were pathogenic for rat but C. parapsilosis and Rhodotorula sp. were not.

This study is a descriptive survey to explore the health lifestyle of adults. The study subjects are teachers of elementary. middle and high school. and staffs of research institutes located in Chungchung Province and Daejon city. The data was collected from Jan. to march 1997 through self reporte for structured questionnaire. Fantastic check list of Wilson and Ciliska for Health Lifestyle Assessment and DSM-III-R for somatic symptom were used as tools. Data was analysed by frequency, $X^2_test$, t-test and Anova using SAS program. The results are as follows: 1. There were statistically significant differences In drinking(t=7.75, P=.000), exercise(t=-2.99, P=.003)and interpersonal relationship(t=2.22, P=.027) among 10 health lifestyle between smoking group and non-smoking group, in drinking(t=17.98, P=.000), exercise(-4.71. P=.000), and job satisfaction(t=2.22, P=.027) between drinking group and non-drinking group, and in eating habit(t=-2.00, P=.045), drinking (t=4.47, P=000), exercise (t= -16.49, P=000), keeping traffic law(t= -2.68, P=.007), personality (t= -2.05, P=.040) and anxiety/depression(t=-3.47, P=.000) between exercise group and non-exercise group. 2. There was statistically significant difference in cardiovascular symptom(F=4.22, P=.0l) among somatic symptoms of subjects according to exercise level. 3. There was statistically significance difference in lifestyle according to smoking level(F=, 3.33, P=.011), drinking level(F=9.17, P=.0001) and exercise level(F=11.93, P=.000l), and in somatic symptom according to sex(t=-3.93, P=.0001), weight(F=3.83, P=.022), exercise level (F=3.29, P=.03) among general characteristics. 4. There was statistically significant difference between sex in general (t= -3.64, P=.0001), gastrointestinal(t=-2.21, P=.02), musculoskeletal(t=-3.92, P=.001), and total symptom (t= -3.92, P=.0001). 5. There was statistically very highly signigicant difference In weight according to smoking($x^2=25.18,\; P=.001)$ and exercise$(x^2=16.46,\; P=001)$. 6. There was statistically significant difference in frequency between smoking group, drinking group and exercise group$(x^2=24.52,\;P=.001)$. Among a number of habit, smoking, drinking and exercise are important factors of human health to prevent related disease morbidity and death. It is essential for industrial health nurse to committ in this subject considering the influence of those factors and lifestyle on health. There is also a relationship of weight with smoking and exercise, the frequency of overweight/obesiy in smoking/ no-exercise group were high. It is quite necessary for the people having cardiovascular symptom to exercise to lower morbidity and mortality. The industrial health nurse has to keep In mind on this point and consider of time and facilities of fitness of employee. It needs to explore the cause by further research on somatic symptom of women. This research shows that concerning the relationship between smoking, drinking, and exercise, health care provider must take not only management of disease, but health behaviors and lifestyle into consideration.

We investigated the effect of energy levels on growth performance, carcass characteristics, and fatty acid composition of Holstein steers at different slaughter ages. Forty Holstein steers with an average body weight (BW) of 234.21 ± 7.42 kg and 7.78 ± 0.22 months were randomly allocated to two experimental groups; a 22-month-old experimental group and a 24-month-old experimental group. Total digestible nutrients (TDN) for each group were set to 70% (T1) and 72% (T2) during fattening phase and 74% (T3) and 76% (T4) for the finishing phase, respectively. No difference was observed in the final BW between the experimental groups during the fattening phase. However, in the finishing phase, the final BW of T4 (820.31 kg) group was significantly higher than that of T1 (745.57 kg; p < 0.05). The average daily gain (ADG) of T2 group in the finishing phase and overall period were 1.27 kg and 1.26 kg, respectively, which were significantly higher than those of T1 (1.11 kg and 1.12 kg; p < 0.05). The feed conversion ratio (FCR) and TDN conversion ratio of T2 group in the finishing phase also decreased by 10.23% and 7.73%, respectively, compared to those of T1. The cold carcass weight of T4 group was significantly higher (p < 0.05) than that of T1, whereas back fat thickness, longissimus area, and marbling score were not significantly different among groups. No differences were observed in physicochemical characteristics of the carcass including moisture, crude protein, and crude fat content among groups. However, the composition of fatty acids differed significantly between the groups. The content of C18:0 was significantly lower (p < 0.05) in T4 than in T1 group, and the content of C18:2 was higher in T4 than in T1 and T3 (p < 0.05). Therefore, feeding Holstein steers at a high-energy feeding level during the fattening and finishing phases improves ADG and reduces the slaughter age from 24 months to 22 months.

Toxoplasma 3 main clonal lineages are designated as type I, II, and III; however, atypical and mixed genotypes were also reported. This study was conducted for detection of Toxoplasma gondii genotypes in rats (Rattus rattus) in Riyadh region, Saudi Arabia. PCR test on T. gondii B1 gene was conducted on ELISA IgM positive samples for confirmation of the infection. However, genetic analysis of the SAG2 locus was performed to determine T. gondii genotypes using PCR-RFLP technique. PCR test on T. gondii B1gene showed that 22 (81.5%) out of the 27 ELISA IgM positive samples have T. gondii DNA. Genotypic analysis shows that, of the total 22 PCR positive samples, only 13 (59.1%) were of type II, 7 (31.8%) were of type III, and 2 (9.1%) were of an unknown genotype. It is obvious that the prevalence of both type II and III is high in rats. No reports have been available on T. gondii genotypes among rats in Riyadh region, and only little is known about its seroprevalence in rats. Future studies on T. gondii genotypes in rats using multi-locus markers is needed in Riyadh region, Saudi Arabia for better understanding of T. gondii pathogenesis and treatment in humans and animals.

The development in the field of the internet of things (IoT) have improved the quality of the life and also strengthened different areas in the society. All cities across the world are seeking to become smarter. The creation of a smart parking system is the essential use case in smart cities. In recent couple of years, the number of vehicles has increased significantly. As a result, it is critical to make the use of technology that enables hassle-free parking in both public and private spaces. In conventional parking systems, drivers are not able to find free parking space. Conventional systems requires more human interference in a parking lots. To manage these circumstances there is an intense need of IoT enabled parking solution that includes the well defined architecture that will contain the following components such as smart sensors, communication agreement and software solution. For implementing such a smart parking system in this paper we proposed a design of smart parking system and also compare it with convetional system. The proposed design utilizes sensors based on IoT and Data Mining techniques to handle real time management of the parking system. IoT enabled smart parking solution minimizes the human interference and also saves energy, money and time.

MQTT protocol is one of open Publish / Subscribe systems for IoT information transmission. In this paper, we are proposing an algorithm to assign a subscriber, which dynamically participate in MQTT clustering system, to an appropriate broker. In MQTT systems with a centralized broker, there are losses of connectivity and messages between subscribers and brokers. In this paper, we addressed this issue for developing scalable open IoT systems and consider clustering MQTT brokers on the SDN infrastructure. In particular, this paper focuses on the problem of allocating subscribers to brokers in accordance with sharing brokers' topics to reduce brokers' load and communication cost in SDN based MQTT cluster. The Experimental results show that the proposed algorithm will reduce the load and the cost as compared to existing methods.
