In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

Background: Recently, adolescent obesity was increased and tended to become obese adults, facing increased risk for diabetes, cardiovascular disease. Even before reaching adulthood, adolescent obesity already was experiencing hypertension, dyslipidemia, and diabetes mellitus. The purpose of this study was to find prevalence of obesity of high school students in Jeju island and association between obesity and cardiovascular risk factors and association between childhood obesity and adolescent obesity. Method: The study subjects were 6,064 students of twenty-two high school in Jeju island and health survey data was gathered from high school health examination data and hospital health examination data from Aug. 1999 to Dec. 1999. Adolescent obesity was evaluated by ideal body weight method in 1998 and body mass index. Cardiovascular risk factors were checked total cholesterol, systolic and diastolic blood pressure, fasting blood sugar. In 1,534 students, obesity at primary school is checked by primary and middle school health record. Results: Prevalence of obesity in Jeju island high school students is 12.6% in male students, 13.3% in female students by ideal body weight method and 8.7% in male students, 8.5% in female students by body mass index. Prevalence of obesity of male students in city area and district area of Jeju island were each 12.9%, 10.3% and that of male students in city area was significantly higher. Prevalence of obesity of female students in city area and district area of Jeju island were each 12.9%, 14.2% and not significantly different. Prevalence of obesity of male students in general and commercial school group were each 13.9%, 10.3% and that of general school group was significantly higher. In female students, Prevalence of obesity general and commercial school group was not significantly different. Total cholesterol, systolic and diastolic blood pressure were significantly associated with degree of obesity in male and female students(P<05) and fasting blood sugar was only significantly associated with degree of obesity in male students(P<05). In 1,514 students checked by health record, Odds ratio of obesity at primary and middle school that at high school were 12.96~22.77 and was significantly associated. Conclusion: Prevalence of obesity of high school students in Jeju island is very high and adolescent obsity was significantly associated with cardiovascular risk factors. Mostly childhood obesity tended to become adolescent obsity and program of control of obesity at childhood and adolescence is required.

The present experiment was done to determine the effects of noradrenaline on the muscle spindle in cats. The reaction site was determined by recording the changes of impulses from group Ia and group Ⅱ muscular afferents of peripheral sensory nerves and dorsal roots. The results are as follows: 1. 36 group Ia muscular afferents were recorded according to extracellular recording and 5 out of 36 showed enhancement of impulse discharge after 1-2 ㎍ noradrenaline injection, 8 showed decrease and 20 showed initial enhancement followed by decrement, but 3 gave no response at all. 2. The administration of KCI solution did not give nay influences to impulse changes of group Ia muscular afferents activated by noradrenaline, however,the injection of bradykinin diminished the decreasing effect of noradrenaline. 3. A small amount of noradrenaline slightly increased the systemic blood pressure but this kind of blood pressure changes was indifferent to the change of the excitability of group Ia muscular afferents from muscle spindle. However, a large amount of noradrenaline increased the blood pressure about 50 ㎜Hg above normal level which influenced the excitatory effect of the muscle spindle. 4. 22 out of 25 group Ⅱ muscular afferents did not show any responses to noradrenaline. Summerizing above results, it could be assumed that the initial excitatory response of group Ia muscular afferents following the injection of noradrenaline was not attributed to vasoconstriction but to direct effects on muscle stretch receptor, and its depressive response were due to the asphyxia resulted from vasoconstriction. And also, it could be suggested that noradrenaline acts on equator region of the muscle spindle, that is, the distribution area of group Ia muscular afferents.

저자들은 Creutzfeldt-Jacob병 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 약 4개월에 걸친 비교적 짧은 기간 동안 중증의 인지 기능 장애와 시각 장애, 보행장애와 하지의 약화, 불수의적 운동 등과 함께 섬망상태에까지 이르게 되어 본원 정신과에 입원하게 되었다. 정신상태 검사상, 반응시간의 지체, 언어장애와 보속증, 시간에 대한 지남력 장애, 주의 집중력 장애, 단기 및 장기 기억 장애, 추상적 사고능력 장애 등의 소견을 보였고, 이러한 증상들은 입원후 치료에도 불구하고 빠르게 악화되었다. 뇌파검사상 지속적인 다발초점성 서파가 모든 전극에서, 특히 우측 전두부에서 현저하게 나타나는 소견을 보였고, 병리조직학적 검사상 대뇌 피질에 신경손실을 동반한 해면화와 신경교 증식증을 나타냈다. 이상의 소견들은 모두 CJD의 진단에 합당하였다. We report a case of Creutzfeldt-Jacob disease and review the relevant literatures. This 56-year-old male patient was admitted to our hospital with a history of rapidly progressing cognitive dysfunction, visual disturbance, gait disturbance, weakness, involuntary movement of lower extremities, and the symptoms of delirium. On mental status examination, he showed psychomotor retardation, speech disturbance, perseveration, disorientation, impairment of short-term and long-term memory, and inability of abstract thinking. He had a rapid downhill course, along with shakiness of trunk, rigidity of the limbs, myoclonus, confusion, and finally, inability to speak or move on the bedside. On electroencephalogram(EEG), continuous multifocal show delta activities were found in all leads, especially in the right frontal areas. Brain biopsy showed, spongiosis with neuronal loss and gliosis noted at the cerebral cortex. These findings were compatible with Creutzfeldt-Jacob disease.

Today, many people stay lot of time sitting on chair in their life. If a sitting posture is not correct, there is some trouble with the waist. And if it goes on long time, sometimes it cause the hurts of waist or the deformded spinal column. A crouched posture is an obstacle to breath and it give rise to drowsiness because the lack of oxygen. Sitting posture is a habit so people can't feel it oneself and look over some kind of risks. It analyzes a condition of muscles by measuring EMG of spinal both side of spinal-bones. It can have a right sitting posture by the analyzing that increasing of muscles tention in one or the other side of muscles when the posture inclines on one side or ahead.
