  • Objective: The purpose of this study was to investigate the effect of types of drive-in initial steps in basketball on technical factors, to provide basic information for the enhancement of basketball skill. Method: Ten men (age: $24.70{\pm}2.26years$; height: $181.00{\pm}5.72cm$; weight: $75.70{\pm}8.23kg$; career length: $10.00{\pm}3.59years$), each with a career length of over five years and no history of injury to the lower extremities within the prior six months, participated in this study. They were asked to perform four types of drive-in movements at $35{\sim}60^{\circ}$, wearing their own shoes, after running from a start line 5 m away and catching a basketball passed by an expert passer. The drive-in movements were measured by eight infrared cameras (Oqus 300, Qualisys, Sweden). Collected raw data were used to calculate total initial step time, displacement, velocity, center of mass (COM) height, and COM velocity. Results: Total initial step displacement and velocity of cross drive-ins (JC, SC) were greater than that of direct drive-ins (JD, SD; p < .05). COM velocity of cross drive-ins (JC, SC) was also greater than that of direct drive-ins (JD, SD; p < .05). Conclusion: Our results indicated that cross drive-ins, regardless of stop step type, are more effective than direct drive-ins. This is because cross drive-ins are technically bold due to less influence from walking violations and double dribble rules in basketball. However, using one-sided movement is too difficult to play in competitive game; therefore, basketball players should develop the ability to choose appropriate movement frequency.

  • Objective: Online pharmacies were introduced in some countries such as United States of America or Canada. They can provide benefits to consumer because they can buy and take conveniently drugs without limitation of location or time. In Korea, online pharmacies are illegal and only pharmacists can sell drugs to consumers or patients. Therefore, we investigated the knowledge of online pharmacy and the possible problem in Korea to survey pharmacists. Methods: We developed questionnaire based on previous articles about online pharmacy and surveyed nation-wide pharmacists by mail or e-mail. The data was analyzed by SPSS and Microsoft Excel. P-values less than 0.05 were statistically significant. Results: 175 pharmacists involved in this study. About introduction of online pharmacies, 53.1% were opposition while 10.3% were approval and 36.6% were conditional. Although online pharmacies were introduced, 46.3% pharmacists do not have a plan to start online pharmacy. However, the approval and tends about starting online pharmacies were higher in younger pharmacists (20s, 30s) (p < 0.05). The criteria of permission about opening online pharmacies were 100% pharmacist license regardless of holding off-line pharmacy. 53.7% pharmacists responded education about taking medication is impossible. When online pharmacies are introduced, 65.1% pharmacists responded traditional pharmacies are affected negatively. Pharmacists concerned that the competition with large-sized distribution corporations, reduced reliance between pharmacists and patients, illegal transaction of counterfeit drugs, increased misuse of drugs. Conclusion: These results showed that Korea pharmacists have negative standard on online pharmacies. Therefore it is required to be more cautious before introducing online pharmacy and it need strict watching system and continuous education and study for safety after introducing online pharmacy.

  • The scale of disasters is very large, also the influence of disasters is irreversible. Korean people has continuously learned how to deal with disaster management law. However, as time goes by after the many disaster, the concern with the disaster management by the people seems to become old and banal topic which nobody has interest in. If so, can it be said that our society is safe from the disaster? This study start from critical mind of asking this question. This study puts an emphasis on the problems such as following; To realize whole concept of disaster management provided in the basic civil defense law, the combined disaster management should be required to be established, the combined law should play a integral part for prevention for the disaster and should be a concrete basis of various laws for disaster management. Establishing a consolidated organization for disaster managing and united response organization is necessary. This consolidated organization is not temporary one such as civil disaster control headquarter but permanent one such as Disaster Management Office which controls an over all aspects of disaster management. Temporary organization should not be divided into natural calamity and man-made calamity but integrated one as a single control tower for all sorts of disasters. The police and army under fire fighting system should be reconsidered. It is necessary to make leadership system on the disaster place more substantial centered around present fire fighting system. To do so, more clear division of duty is required. The working condition should be improved so that all public servants in this agency can play their roles with pride and worth. The resource owned the existing administrative organization must be used by an appointment system. And to manage a large scale of disaster, it is necessary to have interorganizational network system which many specialized organization including volunteer group are integrated. And the natural disaster happen, many professionals and volunteers are distributed to the spots of disaster in the right man in the right place. Finally, citizen's consciousness about safety supervision needs to be recover.

  • The effects of genetic and environmental factors on productivity of a cloned protein were studied in recombinant Saccharomyces cerevisiae. Plasmid stability and copy level were very high for a $REP^+$ system(at ca. 10 generations, stability: 65-90%, plasmid copy number per cell: 40-200), whereas these were very low for a yep- system(at ca. 10 generations, stability: 30%, plasmid copy number per cell 20). In plasmids containing the $2{\mu}m$ circle genome, a $[cir^o]$ strain was a preferred host cell since the plasmid stability and the copy number in a $[cir^o]$ strain were higher than in a $[cir^+]$strain. Cloned gene expression was dependent on plasmid copy number and stability. The inducer (galactose) level played a very important role in cloned lacZ gene expression, showing that a galactose concentration of 0.8% was sufficient for induction of gene expression. Induction rate was very fast in the case of plasmids exhibiting high stability and copy number by a factor of 4 to 25. The time to reach the peak value of gene expression was longer when galactose was added at the start of fermentation (ca. 26 hours) than at the mid-exponential phase (ca. 6 hours). Glucose repression was reduced by a factor of 2 to 5 as the relative inducer level increased.

  • This research is intended to study the dietary experiences by college women to promote women's health through the proper diet. The approach method was used grounded theory. The participants were selected 3 colleges in Seoul, Inchon, and Cheongju. The selected 15 women were college students who had a history of dietary experiences or who were on the way of diet at the time of the start of this research. The data were collected from August 2001 to October 2001. Data collecting method was a Focus Group Interview. The data were analysed by the Strauss and Corbin's method(1966). The results were showed that the 236 concepts in the dietary experiences were gathered into 48 sub-categories, eventually being integrated into 17 higher categories. 'Esthetic self-pursuit' is the core phenomenon of the dietary experiences. Such phenomenon is due to subjects physical problems, sense of comparison and desire of weight-loss. In the circumstantial context, the esthetic self-pursuit phenomenon is enhanced by social opinions, aesthetic senses, and the recognition of self-control. The interaction strategy of the esthetic self-pursuit can be intensified and sustained by will power, supporting systems, and accessibility. Through the dietary experiences, the body changes positive or negative figures. Following the sense of success or failure, the diet are sustained or abandoned accordingly. Therefore for the application of promoting health, an intervention strategy should be created a collect organized diet program in a social level not a private level.

  • The aim of this study was to examine the knowledge and awareness of women in Kuwait with regard to risk factors, symptoms and diagnostic procedures of breast cancer. A total of 521 questionnaires were distributed among women in Kuwait. Results showed that 72% of respondents linked breast cancer factors to family history, while 69.7% scored abnormal breast enlargement as the most detectable symptom of the disease. Some 84% of participants had heard about self-examination, but knowledge about mammograms was limited to 48.6% and only 22.2% were familiar with diagnostic procedures. Some 22.9% of respondents identified the age over 40 years as the reasonable age to start mammogram screening. Risk factor awareness was independent on age groups (p>0.05), but both high education and family history increased the likelihood of postivie answers; the majority knew about a few factors such as aging, pregnancy after age 30, breast feeding for short time, menopause after age of 50, early puberty, and poor personal hygiene. In conclusion, 43.1% of participants had an overall good knowledge of breast cancer with regards to symptoms, risk factors and breast examination. Very highly significant associations (p<0.005) were evident for all groups except for respondents distributed by nationality (p=0.444). Early campaigns for screening the breast should be recommended to eliminate the confusion of wrong perceptions about malignant mammary disease.

  • The probabilistic characterization of wind field characteristics is a significant task for fatigue reliability assessment of long-span railway bridges in wind-prone regions. In consideration of the effect of wind direction, the stochastic properties of wind field should be represented by a bivariate statistical model of wind speed and direction. This paper presents the construction of the bivariate model of wind speed and direction at the site of a railway arch bridge by use of the long-term structural health monitoring (SHM) data. The wind characteristics are derived by analyzing the real-time wind monitoring data, such as the mean wind speed and direction, turbulence intensity, turbulence integral scale, and power spectral density. A sequential quadratic programming (SQP) algorithm-based finite mixture modeling method is proposed to formulate the joint distribution model of wind speed and direction. For the probability density function (PDF) of wind speed, a double-parameter Weibull distribution function is utilized, and a von Mises distribution function is applied to represent the PDF of wind direction. The SQP algorithm with multi-start points is used to estimate the parameters in the bivariate model, namely Weibull-von Mises mixture model. One-year wind monitoring data are selected to validate the effectiveness of the proposed modeling method. The optimal model is jointly evaluated by the Bayesian information criterion (BIC) and coefficient of determination, $R^2$. The obtained results indicate that the proposed SQP algorithm-based finite mixture modeling method can effectively establish the bivariate model of wind speed and direction. The established bivariate model of wind speed and direction will facilitate the wind-induced fatigue reliability assessment of long-span bridges.

  • Background: Gabapentin is widely used for the relief of neuropathic pain. But, there is no study of gabapentin in relation to traumatic neuropathic pain. The aim of this study is to assess the efficacy and effectiveness of gabapentin for the various clinical symptoms of traumatic neuropathic pain Materials and Methods: 50 patients with traumatic nerve injury were assigned to receive gabapentin, titrated to 900 mg/day over 9 days, followed by further increases to a maximum of 2400 mg/day. Continuous pain, paroxysmal pain, allodynia and thermal evoked pain were measured in mean daily pain scores, based on the 11-point Likert scale. The primary efficacy parameter was compared from the baseline to the final study week. Results: Over the 4.5 week study, this pain score decreased by 2.6 points in the continuous pain, 3.6 points in the paroxysmal pain, 3.1 points in the allodynia, and 2.5 points in the thermal evoked pain. The percentage of patients with over 50% improvement in pain scores was 33% in the continuous pain, 67% in the paroxysmal pain, 53% in the allodynia and 36% in the thermal evoked pain. There was no significant correlation between the effect of gabapentin and the time difference of the onset of symptoms and start of medication. Conclusions: This study shows that gabapentin reduced neuropathic pain in patients with traumatic peripheral nerve injury. Among the various characteristics of neuropathic pain, the reduction of paroxysmal pain and allodynia was greatest.

  • The objective of this study was to examine the significance of feeding induced hypovolemia (decrease in plasma volume) in controlling the feed intake of goats fed on dry feed. In order to alleviate hypovolemia with feeding, a 2 h intravenous infusion (16-18 ml/min) of artificial saliva or mannitol solution was begun 1 h prior to feeding and continued until 1h after the start of the 2 h feeding period. In comparison with no infusion (NI), cumulative feed intake was increased by 41% with artificial saliva infusion (ASI) and by 45% with mannitol infusion (MI) by the completion of the 2 h feeding period. Both infusion treatments (ASI and MI) were significantly different (p<0.05) from the NI treatment in terms of the cumulative feed intake. The cumulative feed intake between the ASI and MI treatments was not significantly different (p>0.05). No infusion treatment (NI) had the lowest cumulative feed intake (929 g DM), whereas MI had the highest (1345 g DM), after completion of the 2 h feeding period. Generally, infusion treatments also increased the rate of eating at all time points after feeding was commenced. Following the first 30 mins of feeding, the rate of eating decreased sharply, and subsequently declined gradually in all treatments. Compared to the NI, both ASI and MI significantly (p<0.05) decreased thirst level (water intake for 30 mins after the completion of the 2 h feeding period) by approximately 13%. However, the thirst level caused by ASI and MI was not significantly different (p>0.05). Both ASI and MI decreased the plasma concentrations of osmolality and total protein, and hematocrit at 1 h after infusion. The results suggested that the thirst sensation in the brain could be produced by feeding induced hypovolemia. Moreover, the results indicate that hypovolemia is one of the factors controlling the feed intake of goats fed on dry feed.
