Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

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.

The purpose of this study was to estimate the proportion of user charges out of total treatment costs and to investigate the occuring status of the charge of non-benefit service. The data were collected from 6 hospitals in 3 cities (Seoul 2, Incheon 3, Shihung 1), which containing 1,752 discharge-bills of discharged patients insured by health insurance. The data were analyzed after standardization of the items of non-benefit services. The result are as follows; 1. the average percent of the cost-sharing of discharged patients was 38.1%(benefit : 15.5%, non-benefit : 22.6%) and the proportion of the cost-sharing due to non-benefit services was greater than that due to benefit services. 2. The occurrence rate and the occurred number of non-benefit services were different among hospitals and showed characteristic occurrence rate in individual hospitals. 3. In acute appendicitis, the characteristics of the occurrence rate and the occurred number of non-benefit services by individual hospitals was similar to those of hospitals. It suggest that the hospitals intentionally applied non-benefit item to patients in order to increase their profit. These findings suggest that the burden of cost-sharing is still high especially due to non-benefit services, so it is necessary to extend the coverage of insurance benefits and to develop management system for the appliance of non-benefit services. Regarding the discharge-bill, all service charges should be included in the bill.

Laser heat treatment is an effective technique used to improve the tribological properties and also to increase the service life of automobile components such as camshafts, crankshatfs, lorry brake drums and gears. High power CO₂ lasers and Nd:YAG lasers are employed for localized hardening of materials and hence are of potential application in the automobile industries. The heat is conducted rapidly into the bulk of the specimen causing self-quenching action to occur and the formation of matrensitic structure. In this investigation, the microstructrual features occurring in Nd:YAG laser hardening SM45C and STD_(11) steel are discussed with the use of optical microscopic and scanning electron microscopic analysis. Moreover, This paper describes the optimisation of the processing parameters for maximum hardened depth of SM45C and STD_(11) steel specimens of 10mm thickness by using CW:YAG laser.

The free scapular flap was first described by Dos Santos in 1980. Since then Barwick, Gilbert, Hamiltonn, Urbaniak and Baker reported their cases with good results. The free scapular flap is nourished by the cutaneous brandches of circumflex scapular artery. This artery passes through the triangular space that is bounded by teres minor, teres major and long head of triceps. The free scapular flap has many advantages, especially during the dissection of cutaneous flap, a portion of scapular bone or a portion of teres major muscle can be included according to the necessity of surgical defects. The kinds of flap we used for the reconstruction were cutaneous flap in 8cases, musculocutaneous flap in 1 case, osteocutaneous flap in 2 cases and osteomusculocutaneous flap in 1 case. The results were excellent at donor site and recipient site.

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.
