In this thesis, a method of solving the IP(Internet Protocol) address collision problem on the Web browser in the TCP/IP based on LAN(Local Area Network). These days a number of computers are increasing in geometrical progression, but general users who are not experts are lack of the knowledge about TCP/IP address, by they may use not only their own but also other users' TCP/IP addresses by mistake or intentionally. For the more they may use IP address which is the same as network equipments and then the situation will cause the whole network to be disturbed. As the result it may be happened that not only the original users' network but also the whole users' one do not operate properly in the LAN. In this thesis, the system proposed in this thesis collect address informations of personal computers which are objects of management in local area network and network systems (sever, workstation) and find whether the address informations which are used at that time are the same with the exact which are stored, and then compares with IP address information in the RARP packet on the WEB Browsers. And therefore want to protect the disturbances of network system caused by address change which are occurred by design or by mistakes. It is demonstrated that it can be protected by using the suggested method.

Objectives: As interest in wellness tourism is increasing in Korea, we sought to propose a program with Korean Medicine Contents for eight resorts in Gangwon-do, which has forests and marine resources. Methods: The authors visited eight designated resorts in Gangwon-do, observed the facilities, and interviewed the people in charge. Questions and answers were asked and answered in the form of a questionnaire regarding any deficiencies in the interviews. Afterwards, the contents were analyzed and a Korean Medicine program suitable for each resort was proposed. Results: A total of 17 Korean Medicine Programs were proposed, of which the meditation/yoga program and diet/drink program tailored to each constitution were proposed to be applicable to all 8 resorts. The rest were proposed considering each resort's facilities, environmental characteristics, and main product programs. Conclusions: It appears that the ‘meditation/yoga program’ and ‘constitutional diet and beverage development’ sectors are programs that can be commonly carried out by all facility companies, and for this purpose, the Sasang constitution test and Korean medicine measurement within the resort in Gangwon-do are used to create a program linked to this. In addition, we believe that efforts to improve the program through verification of efficacy will be necessary in the future

Myostatin is a transforming growth and differentiation factor-β family member that acts as a negative regulator of muscle growth. Previously, mutations in the myostatin gene were known to be related to double muscling phenotypes in cattle. Because myostatin gene is highly related to muscle mass, also meat quality, in cattle, we sequenced whole myostatin mRNA and investigated the SNPs (Single Nucleotide Polymorphisms) in Korean cattle (Hanwoo). The results indicated that Hanwoo had an SNP in nt2385 and this mutation can be a useful marker with further verifications. We also investigated expression patterns of the myostatin gene from various muscle tissues and organs. Northern blotting results indicated that myostatin expression was restricted in muscles with variable expression levels. The results presented here can be used as a valuable information for meat quality related traits and muscle mass in cattle.

In order to elucidate the fundamental aspects of the minerals formation processes during sintering, the Fe_2O_3-CaO-Al_2O_3-SiO_2 system and the effect of MgO on synthesized iron ore sinter were studied by image analysis and X-ray diffraction method. Most existed calcium ferrite was identified to be a solid solution of CaO·2Fe_2O_3 with a small amount of solubility of Al_2O_3 and SiO_2. With an increase of the content of Al_2O_3 in the system, the amount of calcium ferrite was increased. On the other hand, the amount of calcium ferrite was decreased, and the amount of hematite was increased with increasing the content of SiO_2. Crystal structure of calcium ferrite with Al_2O_3 and SiO_2 was changed from monoclinic to triclinic as well as the unit cell volume shrank with fixing Al_2O_3 and increasing SiO_2. With increasing the content of MgO(1∼3 wt%), the amount of magnetite was increased and hematite was decreased but calcium ferrite was not changed.

Equilibrium studies for the adsorption of aromatic, alipatic cyclic amines and amino acid from aqueous solutions onto granular activated carbon have been carried out at 298K. Two and Three-parameter isotherms were tested. Among the equations tried, the two-parameter equations of Freundlich equation yield a better fit, The Langmuir equation, However gives the poorest overall fit. For three-parameter isotherm equation, the Redlich-Peterson equation gives the most satisfactory fit over the entire range of concentrations. The adsorption amounts of the aromatic amines onto GAC increase with the number of methyl group in pyridine ring.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Merkel cell carcinoma 의심 환자에 대한 약침치료

박진성, 유준상 상지대학교 한의학연구소 2023 尙志韓醫論文集 Vol.11 No.1

Objectives: Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer known for its poor prognosis. This report aims to present a rare case where traditional Korean medicine, specifically pharmacopuncture, was used as the sole treatment for MCC. Through this case, we seek to explore the potential and limitations of pharmacopuncture as a complementary therapy for rare cancers. Methods: We report a case of a 53-year-old female patient suspected of having relapsed Merkel cell carcinoma 5 months after undergoing surgery for right breast cancer, treated with bee venom pharmacopuncture. Results: Following pharmacopuncture treatment, there was an initial response in terms of tumor size reduction. However, after three months, the tumor size plateaued, and concerns arose about possible metastasis. The diminishing response to phamacopuncture was reminiscent of reports in chemical therapies for MCC, where 55% of patients respond initially, but the response diminishes after three months. Conclusions: For a 53-year-old patient suspected of having MCC after breast cancer surgery, the symptoms improved after 52 sessions of bee venom treatment over a period of about 2 months, showing that bee venom pharmacopuncture treatment has the potential to treat MCC.

Objectives: Under the fee-for-service system, Korean hospitals have been suffering from the worsening profitability caused by law medical care fees. To overcome the difficulties, they have maximized the quantity of medical services and made relatively large investment in developing new medical services using high-priced medical equipment, medicines and medical supplies which were not covered by medical insurance system rather than reduced running costs. Materials and Methods: This study was made to analyze and forecast the revenue change of the department of Obstetrics and gynecology of an university hospital in Seoul, expecting the implementation of DRG system in 2000. Results: The results were as follows : 1.During the first two days of hospitalization. 41% of total medical service fee was occurred, which was thought that most of the check-ups and operations were made during this period. After two days of hospitalization, the new occurrence of medical service fee tended to reduce. 2.Out of total medical service fee, 67% of admission fee was occurred after 5 days of hospitalization. This was because medical service fees in obstetrics and gynecology department occurred during the first 5 days of hospitalization. 3.Out of fees for operation, treatment, medical supplies and blood transfusion. 71% was occurred during the first two days. 4. In case of fees for examination, 50% was occurred during the first two days. 5.A total of 53% of fees for medication and injection was occurred during the first 5 days. Conclusions: By the implementation of the DRG system, the income is forecast to increase by 800 won to 310,000 won by the disease group of obstetrics and gynecology department. To increase hospital income with the implementation of DRG system, the results of this study suggest that examinations should be done at out-patient departments before the hospitalization of patient, the discharge of patient should be noticed in advance to reduce the period of hospitalization, and admission appointment system should be implemented for the immediate operation and delivery.

Many bovine genetic diseases are currently unidentified in Korea because of the relatively low monitoring systems in the livestock farms. The molecular detection system using PCR-RFLP of two genetic diseases, namely Band 3 (Erythrocyte Membrane Protein Band Ⅲ) and CHS (Chediak-Higashi Syndrome), have been identified in Japan and used for screening large number of cattle whether each individual has the genetic disease or not. Using the 22 unrelated Korean cattle (Hanwoo) individuals, molecular detection system based on PCR-RFLP have been investigated, which can be distinguishable carriers for the genetic diseases. Even though we could not found the causative mutations for two genetic diseases, the PCR-RFLP techniques used in this study are very valuable for the screening the genetics diseases in Korean cattle, especially for the proven or candidate bulls.
