ISMP is a method of writing clearly the user requirements in the RFP(Request for Proposal) of the IS development projects. Unlike the conventional methods of RFP preparation that describe the user requirements of target systems in a rather superficial manner, ISMP systematically identifies the businesses needs and the status of information technology, analyzes in detail the user requirements, and defines in detail the specific functions of the target systems. By increasing the clarity of RFP, the scale and complexity of related businesses can be calculated accurately, many responding companies can prepare proposals clearly, and the level of fairness during the evaluation of many proposals can be improved, as well. Above all though, the problems that are posed as chronic challenges in this field, i.e., the misunderstanding and conflicts between the users and developers, excessive burden on developers, etc. can be resolved. This study is a case study that analyzes the execution process, execution accomplishment, problems, and the success factors of two pilot projects that introduced ISMP for the first time. ISMP performance procedures of actual site were verified, and how the user needs in the request for quote are described was examined. The satisfaction levels of ISMP RFP for quote were found to be high as compared to the conventional RFP. Although occurred were some problems such as RFP preparation difficulties, increased workload, etc. due to the lack of understanding and execution experience of ISMP, in overall, also occurred were some positive effects such as the establishment of the scope of target systems, improved information sharing and cooperation between the users and the developers, seamless communication between issuing customer corporations and IT service companies, reduction of changes in user requirements, etc. As a result of conducting action research type in-depth interviews on the persons in charge of actual work, factors were derived as ISMP success factors: prior consensus on the need for ISMP, the acquisition of execution resources resulting from the support of CEO and CIO, and the selection of specification level of the user requirements. The results of this study will provide useful site information to the corporations that are considering adopting ISMP and IT service firms, and present meaningful suggestions on the future study directions to researchers in the field of IT service competitive advantages.

Recently, the Korean Supreme Court released two important decisions concerning damages for the pain and suffering from Aircraft noise. The local people who are living near the Air Force practice site at Maehyang-ri and the Kimpo International Airport brought lawsuits against the Korean government requesting damages for their financial loss from the severe noise and the damages for their pain and suffering. Plaintiffs alleged that they suffered physical malfunctions, extreme disturbances and the reduction of property values from the extreme noises which were daily repeated. District Court of Seoul Province did not allow plaintiffs all but the damages for pain and suffering. Plaintiffs could not prove the causation between their financial loss and the noise. The Supreme Court confirmed the lower court's decision. Article V of the National Compensation Act (analogous to the Federal Tort Claims Act of the USA) reads, "the government shall be liable for any loss caused by the defect on establishment or maintenance of public facilities." In the two cases, the major issue was whether the government's establishment or maintenance of Air Force practice site and the airport was defective because they caused serious noise to surrounding neighbors. Previously, the Supreme Court interpreted the clause "defect on establishment or maintenance of public facilities" as failure of duty to provide safety measures to the degree generally required to ordinary manager. However the Court at this time interpreted differently that the defect could be found if the facility caused to any person loss to the degree intolerable. In the two cases the Court confirmed the lower court's finding that noise level at the site was severe enough to be intolerable. This standard is based on the severity of the loss rather than the failure of duty. It became easier for plaintiffs to prove the cause of action under this interpretation. The consequence of the ruling of these two cases is 'rush to the courtroom' by the local people at similar situations. The ruling of these two cases was not appropriate both in theory and in consequence. The Korean tort system is basically based on the theory of negligence. Strict liability is exceptional only when there is special legislation. The Court created strict liability rule by interpreting the Art. V of the National Compensation Act. This is against the proper role of the court. The result of the cases is also dismal. The government was already sued by a number of local people for damages. Especially the Department of Defense which is operating many airports nationwide has financial hardship, which will cause downsizing military practice by the Air Force in the long run, This is no good to anyone. Tens of millions of dollars which might be used for compensation might be better used to prevent further noise problem surrounding airports.

pH value of sampled fogwater at source regions (above highway and road) in Yongin sites showed the lowest value and was increased after passing the forest stands. Changes of ion concentrations through the forest stands showed a lowering tendency at sampling sites. The fogwater passing the forest stands (Quercus mangolica and Pinus rigida) surrendered acid pollutants to crown and stem from the atmosphere. It was concluded that environmental moisture in the atmosphere is acidified in fogwater. The influence was extended to the pure zone, and the frequency of acid rain has increased. The forests are assumed to remove air pollutants because ion concentrations in fogwater decreased after passing the forests. The fogwater which functions as a local sink for pollutants (H$_2$SO$_4$, HNO$_3$, etc.) falling on plant surfaces is considered to effectively remove acid pollutants. But if the deposition of pollutants exceeds the capacity of purification, it would damage the forest ecosystem. Further investigation is necessary to identify tree species tolerant to acid pollutants.

Purpose : This study was performed evaluate optimal dose for disimpaction, efficacy and safety of PEG 4000 in children with chronic functional constipation. Methods : Eighty six children with chronic functional constipation were enrolled in this prospective study at Konkuk university hospital March, 2003 through August, 2006. Success in disimpaction with PEG 4000 was defined as meeting at least two out of three criteria; resolution of chief complaint, getting easiness of defecation with respect to frequency of bowel movement and hardness of stool based on defecation diary, and decrease in fecal impaction on simple abdominal X-ray test. Adverse effects of PEG 4000 were monitored clinically and biochemically. Results : Eighty three out of 86 children completed the study, and success rate of disimpaction was 99% (82/83). The mean dose of PEG 4000 for disimpaction was $0.93{\pm}0.28g/kg/day$ (0.4-2.0 g/kg/day, Max.: 30 g/day). Frequency of bowel movement increased ($5.02{\pm}2.71/wk$ vs. $11.25{\pm}5.43/wk$) in most children (79/83). Fecal impaction on simple abdominal X-ray test improved with statistical significance in 25 children (P=0.0007). Because of adverse effect of PEG 4000, 3 children did not complete the study; urticaria, severe diarrhea, diarrhea and abdominal pain. One 6-year-old girl who completed the study complained tingling sensation in the hand and foot without laboratory abnormality (4/86, 4.7%). Laboratory test revealed hyperosmolality without clinical symptom in 1 child, and eosinophilia in 6 children. Conclusion : The average safe and effective dose of PEG 4000 for disimpaction was $0.93{\pm}0.28g/kg/day$ (0.4-2.0 g/kg/day, Max : 30 g/day) in children with chronic functional constipation.

Background: The purpose of this study is to improve the quality of the diagnostic procedures in the preoperative evaluation so as to reduce the unnecessary thoracotomy and to ensure resectability in non-small cell lung cancer. Material and Method: Of 616 patients who underwent thoracotomy for primary lung cancer from January 1990 to December 1996, 59 patients(9.6%) turned out to have inoperable lesions after the thoracotomy. We reprospectively reviewed the bronchoscopic findings, methods of tissue diagnosis, CT scans, pulmonary function test and lung perfusion scan, reasons for nonresectability, and adjuvant therapy, and then followed up on the survival rate after exploratory thoracotomy. Result: The cell types were squamous cell carcinoma in 38, adenocarcinoma in 15, large cell carcinoma in 3 and others in 3. Primary loci were RUL in 20, RML in 6, RLL in 8, LUL in 13, LLL in 4 and others in 8. The reasons for non-resectability were various; direct tumor invaison to mediastinal structures(n=41), seeding on pleural cavity(n=8), poor pulmonary function(n=2), invasions to extranodal mediastinal lymph node(n=2), technical non- resectability due to extensive chest wall invasion (n=3), small cell carcinoma (n=1), malignant lymphoma(n=1), and multiple rib metastases(n=1). In the follow-up of 58 patients, 1-year survival rate was 55.2% and 2-year survival rate was 17.2% and the mean survival time was 14 months. When compared according to cell types or postoperative adjuvant therapeutic modalities, no significant difference in the survival rates were found. The squamous cell carcinoma was frequently accompanied by local extension to contiguous structures and was the main cause of non-resectability. In adenocarcinoma, pleural seeding with malignant effusion was frequently encountered, and was the major reason for non-resectability. Conclusion: These data revealed that if appropriate preoperative diagnostic tools had been available, many unnecessary thoracotomies could have been avoided. Both the use of thoracoscopy in selected cases of adenocarcinoma and the more aggressive surgical approach to the locally advanced tumor could reduce the incidence of unnecessary thoracotomies for non-small cell lung cancers.

This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.

During the 1990s, policy was put in place to create resting spaces in rural areas. This policy was associated with a government project to improve the rural residence environment and it attracted attention to outdoor spaces in rural areas. Many communities have gradually disappeared in rural areas but previous studies suggested that legally protected trees might provide resting and cultural spaces in a given rural community. The rural residential environment can be improved by legally protected trees and by doing so, these resources may then help to sustain many rural communities. Therefore, the creation of resting spaces or mini-parks created around trees that are protected by in rural communities should be considered. The value of trees that are protected by law can differ depending on the status of the trees or the surroundings. Nevertheless, there has not been systemic research regarding legally-protected trees in terms of rural communities. This study aims at evaluating the potential of these trees and at analyzing how these trees can be useful in the creation of community spaces in rural areas. The findings can be helpful in providing foundation data for creating these types of community spaces. Forty legally protected trees in Gimchon City were selected for this study. Nine items were used to evaluate the potential of the trees for creating community spaces. These items could be classified into five factors including accessibility, relation to public facilities, environment and safety, symbolism, and ease for creating community spaces. The potential of the legally protected trees was evaluated by 5-point Likert Scales in a given item. The overall potential was evaluated by the sum of individual item scores. Specifically, trees with over 20 points (max. 25 points) could be considered high potential. According to the empirical findings, the portion of legally protected trees with high potential is five percent (No.7 and No.12 trees). Therefore, the priority is to protect or use the trees for the creation of community spaces that can help make a better residential environment for rural communities.

Around the turn of 21st century, there has been a major technological shift in the animation industry. With development of reality-based computer graphics, major American animation studios replaced hand-drawn method with the new 3D computer graphics. Traditional animation was known for its simplified shapes such as circles and triangle that makes characters' movements distinctive from non-animated feature films. Computer-generated animation has largely replaced it, but is under continuous criticism that automated movements and reality-like graphics devaluate the aesthetics of animation. Although hand-drawn animation is still produced, 3D computer graphics have taken commercial lead and there has been many changes to acting of animated characters, which calls for detailed investigation. Firstly, the changes in acting of 3D characters can be traced from looking at human-like rigging method that mimics humanistic moving mechanism. Also, if hair and clothing was part of hand-drawn characters' acting, it has now been hidden inside mathematical simulation of 3D graphics, leaving only the body to be used in acting. Secondly, looking at "Stretch and Squash" method, which represents the distinctive movements of animation, through the lens of media, a paradox arises. Hand-drawn animation are produced frame-by-frame, and a subtle change would make animated frames shiver. This slight shivering acts as an aesthetic distinction of animated feature films, but can also require exaggerated movements to hide the shivering. On the contrary, acting of 3D animation make use of calculated movements that may seem exaggerated compared to human acting, but seem much more moderate and static compared to hand-drawn acting. Moreover, 3D computer graphics add the third dimension that allows more intuitive movements - maybe animators no longer need fine drawing skills; what they now need is directing skills to animate characters in 3D space intuitively. On the assumption that technological advancement and change of artistic expressionism are inseparable, this paper compares acting of 3D animation studio Pixar and classical drawing studio Disney to investigate character acting style and movements.

Glycyrrhizae radix is one of the most frequently prescribed ingredients in Oriental medicine, and Glycyrrhizae radix extract has been shown to exert anti-cancer effects. However, the cellular and molecular mechanisms of programed cell death (apoptosis) by Glycyrrhizae radix are poorly defined. In the present study, it was examined the molecular mechanisms of apoptosis by water extracts of Glycyrrhizae radix (GRW) in human bladder T24 cancer cells. It was found that GRW could inhibit the cell growth of T24 cells in a concentration-dependent manner, which was associated with the induction of apoptotic cell death, as evidenced by the formation of apoptotic bodies, DNA fragmentation and increased populations of annexin-V positive cells. The induction of apoptotic cell death by GRW was connected with an up-regulation of pro-apoptotic Bax protein expression and down-regulation of anti-apoptotic proteins (Bcl-2 and Bcl-xL), and inhibition of apoptosis family proteins (XIAP, cIAP-1 and cIAP-2). In addition, apoptosis-inducing concentrations of GRW induced the activation of caspase-9, an initiator caspase of the mitochondrial-mediated intrinsic pathway, and caspase-3, accompanied by proteolytic degradation of PARP. GRW also induced apoptosis via a death receptor-mediated extrinsic pathway by caspase-8 activation, resulting in the down-regulation of total Bid and suggesting the existence of cross-talk between the extrinsic and intrinsic pathways. Taken together, the present results suggest that GRW may be a potential chemotherapeutic agent for the control of human bladder cancer cells.

Recently, interest in the harmful factors of particulate matter (PM), a major component of air pollution, has been increasing. In particular, PM_2.5 with a diameter of less than 2.5 ㎛ is well known to induce oxidative stress accompanied by autophagy in human lung epithelial cells. However, studies on whether PM_2.5 increases autophagy under oxidative stress and whether this process is reactive oxygen species (ROS)-dependent are insufficient. Therefore, in this study, we investigated whether PM_2.5 promotes autophagy through the generation of ROS in human alveolar epithelial A594 cells. According to our results, cells co-treated with PM_2.5 and hydrogen peroxide (H₂O₂) showed a lower cell viability than cells treated with each alone, which was associated with increased total and mitochondrial ROS production. The co-treatment of PM_2.5 and H₂O₂ also increased autophagy induction, which was confirmed through Cyto-ID staining, and the expression of autophagy biomarker proteins increased. However, when ROS generation was artificially blocked by N-acetyl-L-cysteine pretreatment, the reduction in cell viability and induction of autophagy by PM_2.5 and H₂O₂ co-treatment were markedly attenuated. Therefore, the present results suggest that PM_2.5-induced ROS generation may play a critical role in autophagy induction in A549 cells.
