Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.

This paper deals with the life history of Sericinus telamon Donovan, based on field and laboratory observations conducted during the spring, 1960 to the fall, 1962 in Kwangnung, central Korea. 1. This species is widely distributed throughout Korea except Dagelet Island and Quelpart Island. It is also very common in Kwangnung. 2. The food plant of this species is Aristolochia contorta Bunge. 3. Egg: The shape is hemispherical, 0.8㎜ in diameter, 0.7㎜ in height. The color is orange. Its surfase is smooth and shinning with irregular brown spots on it. Egg period is 5―8 days. 4. Larva: It lasts from the middle of April to the end of May in the first generation, from the middle of June to the end of July in the second generation, and from the end of August to the end of September in the third generation. The larval stage consists of five instar. Each instar larval period is as follows: 1st instar, 1―2 days; 2nd instar, 3―4 days; 3rd instar, 3―4 days; 4th instar, 3―4 days; and final instar, 6―7 days. Final instar larva is black in color and there are many spines on it. The number of spines starting from prothorax toward tenth abdominal segment is 2·6·6·6·6·4·4·4·4·2·2. In particular, a pair of spines (6㎜ in length) on the subspiracular of prothorax is larger and longer than others and point forward and the larva wields it like and antenna in movement. 5. Pupa: Average length is 28㎜. The color is dark brown with irregular black stripes on its back. Each pupa has peculiar difference in the pattern of these stripes. The larva pupates on the underside of either a leaf of food plant or a leaf around food plant. Pupal period of the first and second generation is about 10―12 days, but the pupa of the third generation stays overwinter. 6. Adult: It emerges thrice a year. It occurs from the middle of April to the beginning of May, the middle of June to the end of June, and the end of July to the end of April. It lays eggs on a stem of the food plant. The average number of eggs in a group is 38, ranging from 12 to 95.

Purpose : The purpose of this study is to determine effects of aromatherapy on the activity and balance of autonomic nervous system and on physical resistance to stress. Methods : This research is a primitive experimental design which attempts to analyze aromatherapy EKG monitoring on real-time basis. Lavender & Chamomile, each 30 drops, were blended with 100ml Sweet Almond oil. Subjects was laid relaxed, and had insides of his wrists and ankles attached with electrodes for EKG. Right after applied with essential oil onto his philtrum and parotid, started on EKG monitoring. Results : The activities of parasympathetic and sympathetic nerve were changed as time elapsed, with significant differences(p=.000). In multiple comparison, the value was significantly different (p<.05).The balance of autonomic nerve was changed, becoming close to the normal level in accord with applicable international standards(1.5)(p=.011). In multiple comparison, the value showed a significant difference(p<.05). Physical resistance to stress increased with the passage of time, but not statistically significant. Conclusions : This suggests that aromatherapy can be used as a nursing intervention which aims at alleviating symptoms related to the imbalance of autonomic nerve system such as headache, hot flashes, irregular heartbeat, nervousness, depression and anxiety.

Poly(p-phenylenesulfide)와 poly(p-phenylene)으로부터 제조된 탄소를 리튬이온 2차전지용 음극재료로 사용하여 전기화학적특성을 연구하였다. 이들 고분자들을 질소 분위기하에서 승온속도 2℃/min로 1000℃까지 상승시킨 후, 1시간 동안 탄화시켜 탄소를 제조하였다. Poly(p-phenylene)으로부터 제조된 탄소가 보다 더 규칙적인 구조를 가지기 때문에 Poly(p-phenylenesulfide)으로부터 제조된 탄소보다 더 많은 용량과 충방전 효율을 나타내었다. 수산화리튬과 염화주석(Ⅱ)을 첨가하여 용량의 증가와 충방전 효율의 증가를 가져올 수 있었다. 이중에서 poly(p-phenylene)에 염화주석(Ⅱ)을 첨가시켜 제조된 탄소가 가장 큰 충방전 용량과 충방전 효율의 향상을 가져왔다. Carbon inaterials manufactured from poly(p-phenylene sulfide) and poly(p-phenylene), were studied on electrochemical characteristics as anode materials for lithium ion secondary battery. These polymer precursors were heat treated for 1hr at 1000℃ with the rate 2℃/min under nitrogen atmosphere. Carbon manufactured from poly(p-phenylene) showed higher capacity and coulomb efficiency of charge/discharge than carbon from poly(p-phenylene sulfide) because the former has better ordered structure. Carbon manufactured from polymer precursors adding stannous chloride or lithium hydroxide showed higher capacity and better efficiency of charge/discharge. Also, carbon manufactured by adding stannous chloride to poly(p-phenylene) showed the highest capacity and efficiency of charge/discharge.

In recent years, the knee extensor forces of athletes have usually been evaluated by measuring isokinetic output torque. The purpose of this study was to confirm the usefulness of nonmalizing the torque(force)-velocity curve and calculating the maximal power of knee extensor under isokinetic contraction. Seventy two(46 elite, 26 non-elite) Japanese male sprinters were chosen as the subjects in this study. The peak torque of the dominant side of knee extensor was measured by using the isokinetic dynamometer (Cybex Ⅱ+) in three different angular velocities of 60, 180, 300deg/sec. Moreover, the isometric torque (0deg/sec) was measured in 39 athletes, 120 and 240deg/sec of contraction were performed in 12 out of 39 athletes. The exponent equation (F=F0×eav-kv: Fenn 1935) was applied to normalize the torque-velocity curve without including the coefficient of viscosity(k). The maximal power and its optimal velocity was presumed from this torque-velocity curve. The average of measured torque at 0 deg/sec contraction(F0) was lower than that of 60 deg/sec, therefore F0 was presumed as the same as the maximal power. Those parameters were not significantly different when calculated from 3 velocities (60, 180, 300 deg/sec) and 5 velocities (plus 210, 240 deg/sec) in 12 athletes. For this reason, each parameter was calculated from 3 velocities. The maximal torque (F0/BW) was the same between elite and non-elite group (40Nm/㎏). Nevertheless, the coefficient of torque loss(a), maximal power and its optimal velocity were significantly different (-0.1594 : -0.1911, 9.6 : 7.8watt/㎏, 373 : 309 deg/sec, respectively. P<.01 Student-t). It was said that to normalize the torque-velocity curve or to presume the maximal knee extension power and its optimal velocity were useful to assess the muscle function or the performance of athletes under isokinetic contraction.

본 논문은 다른온도로 소성한 왕겨를 콘크리트 흔화재로 사용한 콘크리트의 강도특성을 알아보기 위한 것으로 물결합재비를 35% 로 고정하고 왕겨의 혼입률을 각기 달리하여 소성온도에 따른 압축강도 특성과 왕겨의 혼입률에 따른 강도특성을 평가하였다. 실험결과 왕겨가 혼화재로서 성능을 발휘하는 최저 온도가 600℃인 것으로 나타났으며, 700℃로 소성한 경우 가장 우수한 강도 값을 나타내었다. 또한 혼입률별 압축강도 특성에서는 혼입률 10% 에서 가장 우수한 강도발현을 나타내었다.
