Purpose: The aim of this study was to evaluate the effect of a breathing exercise intervention by measuring pulmonary function test (PFT) three times; preoperative, 3rd and 5th day after operation. Methods: This study was designed as a non-equivalent control group pretest-posttest design. A total of 55 patients with lung cancer were recruited from a Chonnam university hospital in Hawsun-gun, Korea from January to December 2008. Results: 'Forced Vital Capacity (FVC)' and 'Forced Expiratory Volume in 1 second $(FEV_1)$' were significantly improved in the experimental group than those in the control group (p<.05). Conclusion: Breathing exercise intervention was found to be effective in improving pulmonary function among lung cancer patients underwent lung lobectomy. Thus, the breathing exercise can be applied in hospitals and communities for patients with lung cancer as one of the nursing intervention modalities for their better postoperative rehabilitation.

The portfolio selection is one of the most important and vital decisions that a real or legal person, who invests in stock market, should make. The main purpose of this article is the determination of the optimal portfolio with regard to relations among stock returns of companies which are active in Tehran's stock market. For achieving this goal, weekly statistics of company's stocks since Farvardin 1389 until Esfand 1390, has been used. For analyzing statistics and information and examination of stocks of companies which has change in returns, factors analysis approach and clustering analysis has been used (FC approach). With using multivariate analysis and with the aim of reducing the unsystematic risk, a financial portfoliois formed. At last but not least, results of choosing the optimal portfolio rather than randomly choosing a portfolio are given.

Collagen is widely used for regenerative therapy and pharmaceutical applications as one of the most useful scaffolds. Collagen is the most abundant protein in vertebrates and the natural substrate of various types of animal cells. Bone and dentin are mineralized tissues and almost similar in chemical components. They consist of collagen (18%), non-collagenous proteins (2%), hydroxyapatite (70%) and body fluid (10%) in weight volume. Pepsin-digested, type I collagen (atelocollagen) and heat-denatured collagen (gelatin) are basic collagenous materials for medical use. Demineralized dentin matrix (DDM) and demineralized bone matrix (DBM) belong to acid-insoluble group, and vital tooth-derived DDM is a unique dentin material including cementum and growth factors. In this review, collagen-based materials will be introduced and discussed for bone regenerative surgery.

The present study analyzes the diversity and usage of NTFPs and evaluates their importance in the day to day life of the people of rural Meghalaya. People use 172 NTFPs belonging to 139 plant species mainly for food, medicine and fuelwood and to a lesser extent for construction, handicrafts and ornamental purpose. These 139 plants belonged to 117 genera and 70 families with Rosaceae, Poaceae and Fagaceae families as the dominant NTFP yielding families. Fruits from shrubs and trees are most commonly harvested by people. Collection and availability of NTFPs for use as food are more during the summer season, which is also the period with least availability of job. NTFPs for subsistence use are greater in number than those having commercial value. The most commonly harvested plant parts are fruits and leaves. Roots, rhizomes and whole plants are extracted in lesser quantity which is a positive approach from sustainability point of view. NTFPs and other forest products also form a vital part of the rural household's income generation activities.

The tumour lysis syndrome (TLS) is a group of metabolic abnormalities caused by rapid and unexpected release of cellular components into the circulation as a result of massive destruction of rapidly proliferating malignant cells. It usually develops in patients with hematologic malignancies like acute lymphoid leukemia, non-Hodgkin and Burkitt's lymphoma after initiation of chemotherapy or may, rarely, occur spontaneously. Though TLS is seldom observed in relation to solid tumours, there have been reports of connections with examples such as lung, liver, breast, gastric carcinomas. The clinical manifestations of TLS include hyperuricemia, hyperkalemia, hyperphosphatemia and hypocalcemia. These indications if untreated lead to life-threatening complications such as acute renal failure, cardiac arrhythmias, seizures, and eventually death due to multiorgan failure. Therefore early detection of TLS is of vital importance. This can be accomplished by identification of high risk patients, implementation of suitable prophylactic measures andmonitoring of the electrolyte levels in patients undergoing chemotherapy.

Cholesterol is a vital component of the human body. It stabilizes cell membranes and is the precursor of bile acids, vitamin D and steroid hormones. However, cholesterol accumulation in the bloodstream (hypercholesterolemia) can cause atherosclerotic plaques within artery walls, leading to heart attacks and strokes. The efficiency of cholesterol absorption in the small intestine is of great interest because human and animal studies have linked cholesterol absorption with plasma concentration of total and low density lipoprotein cholesterol. Cholesterol absorption is highly regulated and influenced by particular compounds in the food supply. Therefore, it is desirable to learn more about natural food components that inhibit cholesterol absorption so that food ingredients and dietary supplements can be developed for consumers who wish to manage their plasma cholesterol levels by non-pharmacological means. Food components thus far identified as inhibitors of cholesterol absorption include phytosterols, soluble fibers, phospholipids, and stearic acid.

Since the internet is open to public in 1990, electronic commerce(EC) user has increase rapidly. Now EC is considered not only as communication method but also as new economical activities. EC is a kind of new commerce model which uses electronic means. And EC has global characteristics so that many country's legislation which regulates it differently makes an obstacle to vital of EC. The purpose of this study is to examine legal problems of internet electronic commerce. First, there are some legal problems whether electronic document has same legal function like traditional documents. Second, electronic signature must has authenticity, integrity, non-repudiation, writing and confidentiality in order to use looks like common signature. Finally, electronic contract is concluded on principle of mutual agreement. It is apparent that the concept of arrival is applied to the date and place in conclusion of electronic contract.

By no means rapid advances in technology affects the working and improvement of all systems built to increase the quality/standards of human living. Information technologies as the main driving force of technological progress today happen to be a sine qua non for all organizations hoping to keep pace with or surpass rivals. However, despite their vital advantages it is true that these create undesirable side effects that harm social systems and the rights of persons. Similar to all others in the world Turkey is trying to cope with the problem through creating an appropriate legal and administrative substructure trusted to discontinue or at least minimize such criminal acts.

Sound pressure level, subglottic air pressure, vital capacity, adduction/abduction rate, and phonatory efficiency were measured in 19 opera singers, 17 Korean traditional 'Pansori' singers, and 20 non-singers; subjects' mean age was 25.9(SD=7.2) and the singers had been singing professionally for 5-10 years. One-way ANOVA and Scheff$\w'{e}$ post-hoc analysis were used to analyze aerodynamic data and to identify significant differences among groups. Sound pressure level, peak subglottic air pressure, and phonatory efficiency were found to be significantly different among three groups of the subjects. Differences in aerodynamic properties were discussed for their significance in diagnosis and treatment of voice disorders in professional singers.

The purpose of this study was to apply the photoplethsmography(PPG) as a non-invasive tool to evaluate the blood flow of the anterior tooth in clinic. The system consist of two light-emitting diodes(LED) powered by 5V as the light source. The LED was designed to two weve lengths, 940(infrared) and 660(red)nm simultaneously with a 36nm bandwidth at half the peak intensity. The 54 anterior vital tooth were examined and the measured was analysed in frequency domian (power spectrum).(omitted)
