  • Ten patients with deep muscle-invading bladder carcinoma (clinical stages T3a to T4b) who were not candidates for cystectomy were treated with combined modality treatment with transurethral resection, cisplatin chemotherapy and pelvic irradiation from 1989 through 1990, and were analyzed retrospectively. All patients were not candidates for cystectomy because the tumors were judged unresectable or they were not fit for a radical cystectomy. Of the patients 5 had clinical stage T3a, 3 stage T3b and 2 stage T4b disease. The minimum follow-up was 16 months. The complete response rate is 60$\%$ for all patients. The complete responses were achieved in 4 of 5(80$\%$) with stage cT3a, in 2 of 3(67$\%$)with stage cT3b and in none of 2(0$\%$) with stage cT4b. The partial responses were achieved in 2, so an overall response rate was 80$\%$. All six patients with grade I or II transitional cell carcinoma showed complete responses. Four patients with higher grade tumors showed partial responses in 2 and no response in 2, and all died of their bladder cancer. Six patients who showed complete responses after treatment are alive and only one of them showed a local recurrence 10 months after treatment. Distant metastases developed in 3 patients: lungs in 2(cT4b) of those who were never locally free of disease and spine in 1 patient (cT3b) among those with a partial response. Two patients died of metastases to lungs. During the follow-up diarrhea occurred in one which was improved after conservative treatment. On the basis of this analysis it is suggested that combined modality treatment seems to be a tolerable regimen and can be offered with a relatively high probability of success and conservation of bladder function in those with less advanced tumors by clinical stage and low grade.

  • As the local self-government are stabilized and the environmental value is becoming more important among local residents, the occurrence of the anti-movements against waste treatment facilities is getting more frequent. Opposing to build the reuse facilities of wastes takes place because of concerning of health and hygiene, as well as matters of unclear policy making process. However, these facilities must be built in somewhere for the convenience and profit of the public. The NIMBY phenomenon against reuse facilities of wastes could be a burden for the city operation system, and it could worsen citizens' quality of life in the long run. In these lights, reuse and recycling facilities of wastes in East region are necessary facilities improving citizens' quality of life and enhancing the growth of cities in the region. However, there have been concerning of deforestation during the construction process of the facilities. The landscape design presented here for these facilities considers the features of the environmental ecosystem and tries to establish a plan to preserve the natural environment of the City of Ichon. This paper presents methods minimizing adverse effects of the facilities on the existing environments and promoting the city image with integrating culture, tourism, landscape and environment of the city. The landscape design makes efforts to harmonize natural environments in the site, human activities and culture. Well-being park was aimed to lead healthy and energetic outdoor activities of local residents. Ecological park was aimed to enhance the ecological functions of the forests and restore the valley ecology. Culture park was aimed to capture the city identity by creating a place that contains all the variety of meanings of the City of Ichon.

  • Background Currently, breast conservation therapy is commonly performed for the treatment of early breast cancer. Depending on the volume excised, patients may require volume replacement, even in cases of partial mastectomy. The use of the latissimus dorsi muscle is the standard method, but this procedure leaves an unfavorable scar on the donor site. We used an endoscope for latissimus dorsi harvesting to minimize the incision, thus reducing postoperative scars. Methods Ten patients who underwent partial mastectomy and immediate partial breast reconstruction with endoscopic latissimus dorsi muscle flap harvest were reviewed retrospectively. The total operation time, hospital stay, and complications were reviewed. Postoperative scarring, overall shape of the reconstructed breast, and donor site deformity were assessed using a 10-point scale. Results In the mean follow-up of 11 weeks, no tumor recurrence was reported. The mean operation time was 294.5 (${\pm}38.2$) minutes. The postoperative hospital stay was 11.4 days. Donor site seroma was reported in four cases and managed by office aspiration and compressive dressing. Postoperative scarring, donor site deformity, and the overall shape of the neobreast were acceptable, scoring above 7. Conclusions Replacement of 20% to 40% of breast volume in the upper and the lower outer quadrants with a latissimus dorsi muscle flap by using endoscopic harvesting is a good alternative reconstruction technique after partial mastectomy. Short incision benefits from a very acceptable postoperative scar, less pain, and early upper extremity movement.

  • Standard therapy for advanced head and neck cancer consists of a combination of surgery and radiation. However, survival of this patient population has not improved during the past 20 years. Many different multimodality treatment schedules have been proposed, and chemotherapy is often used with the intent of organ preservation. The present study was intended to establish the efficacy of concomitant chemoradiation with a single agent carboplatin in advanced head and neck cancers.The objectives were to investigate the feasibility of concomitant administration of carboplatin, monitor acute toxicity during radiotherapy, and determine subacute side effects, such as wound healing following surgery after chemoradiotherapy. A prospective study was conducted wherein a total of 40 patients with stage III and IV squamous cell carcinomas of oral cavity, oropharynx, hypopharynx and larynx were enrolled. All patients were treated with external beam radiotherapy and weekly carboplatin area under curve (AUC of 5). Radiotherapy was given in single daily fractions of 1.8-2 grays (Gy) to a total dose of 66-72 Gy. Salvage surgery was performed for any residual or recurrent locoregional disease. Neck dissection was recommended for all patients with neck disease showing less than a complete response after chemoradiation. A total of 40 patients were enrolled of whom 32 were males and 8 were females. Highest incidence of cancer was seen in the 5th-6th decades of life with a median age of 47.7 years. Oropharyngeal tumours constituted a maximum of 21 patients followed by hypopharynx in 10, larynx in 7 and oral cavity in 2. 80% of the patients had a neck node on presentation of which 40% had N2-N3 nodal status. TNM staging revealed that 58% of patients were in stage III and 43% in stage IV. Evaluation of acute toxicity revealed that 50% had grade II mucositis, 25% grade III mucositis, 2.5% grade IV mucositis. 50% of patients had grade I skin reactions, 65% of patients had grade I thrombocytopenia, and 24% of patients had grade I anaemia. After completion of treatment 65% of patients had complete response at the primary and regional sites, and 35% of patients had a partial response of whom 23% underwent neck dissection and 5% of them underwent salvage surgery at the primary site. At the end of one year there were six deaths and four recurrences and 70% were free of disease. Concurrent chemoradiation with carboplatin provided good locoregional control for locally advanced head and neck cancers. This regimen, although toxic, is tolerable with appropriate supportive intervention. Primary site conservation is possible in many patients. Chemoradiotherapy appears to have an emerging role in the primary management of head and neck cancers.

  • In the case of radiotherapy following breast conservation therapy for breast cancer patients, the characteristic of skin dose was investigated in the treatment of intensity modulated radiation therapy (IMRT) for breast cancer patients by comparing and analysing entrance skin dose irradiated during radiotherapy using tangential technique radiotherpy, and IMRT. The calculation dose irradiated to breast skin was compared with TLD measurement dose in treatment planning by performing the two methods of radiotherapy using tangential technique, and IMRT in treatment planning equipment. The skin absorbed dose was measured to pass a nipple by spacing of 1 cm distance from center to edge of body. In the radiotherapy of tangential technique, for the irradiation of 180 cGy to PTV, the calculation dose was ranged from 103.5 cGy to 155.2 cGy, measurement dose was ranged from 107.5 cGy to 156.2 cGy, and skin dose in the center was maximum 1.45 times more irradiated than that in the edge. In the IMRT, for the irradiation of 180 cGy to PTV, the calculation dose was ranged 9.8 cGy at 80.2 cGy, measurement dose was ranged 8.9 cGy at 77.2 cGy, and skin dose in the center was maximum 0.23 times less irradiated than that in the edge. IMRT was more effective for skin radiation risks because radiation dose irradiated to skin in IMRT was much less than that in radiotherapy of tangential field technique.

  • This research was performed to develop mass propagation method of Alpine modest primrose (Primula modesta var. hannasanensis T.Yamaz.) for improving the conservation and utilization of the species. Seeds were collected on August 2011 in Jeju-city and well-selected seeds were dry-stored at $4{\pm}1.0^{\circ}C$. Seed size ranged $0.44{\pm}0.07{\times}0.61{\pm}0.04mm$, and weight of 1,000 seeds was $51.78{\pm}0.021mg$. Thus the seed was classified as 'dwarf seeds'. As the result of dormancy characteristics, moisture content of freshly matured seeds increased rapidly by water-soaking treatment and seeds did not germinate at $20^{\circ}C$ for 4 weeks under the light condition. Therefore, seeds were estimated to have physiological dormancy. Germination conditions of dry-stored seeds were found to be $20^{\circ}C$ and light condition, and seeds did not germinated under dark condition regardless of all temperature regimes. Therefore, Alpine modest primrose seed was considered as photoblastic type. Percent germination (PG) and germination energy (GE) were greatly improved by soaking the seeds in $GA_3$ and kinetin for 24 hours. Especially, 200~500 mg/L $GA_3$ treatment resulted in the highest PG (95.5%) and GE (98.3%). So, chemical treatment such as $GA_3$ was thought to be a useful method for raising seedling uniformly.

  • Objective: The primary goal was to identify the effectiveness of chemical or biological additives in delaying the deterioration of early-harvested wilted rye silage after exposure to air. Methods: Rye harvested as a whole plant at the early heading stage was wilted for 24 h. The wilted forage was divided into treatments including sodium diacetate (SDA) at 3 (SDA3) and 6 g/kg (SDA6), Lactobacillus plantarum (LP), L. buchneri (LB), or their equal mixture (LP+LB) at 1×106 colony-forming unit/g fresh matter. Results: After 60 d of conservation in 20-L silos, lactic acid was greater in LP and LP+LB silages than other treatments (102 vs 90.2 g/kg dry matter [DM]). Acetic acid was greatest in SDA6 (32.0 g/kg DM) followed by LB (26.1 g/kg DM) and was lowest in LP treatment (4.73 g/kg DM). Silage pH was lower with microbial inoculation and the lowest and highest values were observed in LP and untreated silages, respectively. After 60 d, neutral detergent fiber concentration was lowest in SDA6 silages, resulting in the greatest in vitro DM digestibility (846 g/kg DM). Aerobic stability was longest in SDA6 (176 h) followed by LB treatment (134 h). Instability after aerobiosis was greatest in LP silages (68 h), about 8 h less than untreated silages. After aerobic exposure, yeast and mold numbers were lowest in SDA6 silages, resulting in DM loss minimization. Exhaustion of acetic acid and lactic acid after aerobic exposure was lowest with SDA6 but greatest with untreated and LP silages. Conclusion: Treatment of early-cut wilted rye forage with SDA at 6 g/kg resulted in silages with higher feeding value and fermentation quality, and substantially delayed deterioration after aerobic exposure, potentially qualifying SDA at this load for promotion of silage quality and delaying aerobic spoilage of early-harvested (low DM) rye forage.

  • Recently, the domestic plant disease control policy for fire blight has been implemented partial control in addition to burial control. In this study, an on-site management survey was conducted targeting orchards that implemented partial disease control from 2019 to 2020 in order to find efficient implementation methods for partial disease control. As a result of an investigation into 22 pear and apple orchards in Cheonan and Chungju, 7 orchards were buried. The upper part of the cut infected plants was burned at 16 orchards and covered with plastic vinyl after lime treatment at 6 orchards. The lower stumps of cut infected plants were burned at 7 orchards and covered with plastic vinyl after lime treatment at 15 orchards. There were two orchards where suckers appeared on the stumps even though covers were applied. There was no infection by Erwinia amylovora in the suckers. The conservation condition of lime treatment was good, but warning signs were absent at 6 orchards. Most orchards treated the stumps and surrounding areas with glyphosate-isopropylamine herbicide. The effect of partial control was judged to be safe.

  • The SNF2/SW12 family comprises proteins from a variety of species with in vivo functions, such as transcriptional regulation, maintenance of chromosome stability during mitosis, and various types of DNA repair. This study was shown the characterization of hrp2+ gene which was isolated by PCR amplification using the conserved domain of SNF2 motifs. Sequence analysis of hrp2+ gene showed striking evolutionary conservation among the SNF2 family of proteins. The transcript of hrp2+ gene was found to be a 4.7 kb as identified by Northern hybridization. In addition, to determine the transcription initiation site of hrp2+ gene, primer extension analysis was performed. This result showed the band of 64 bp. The transcriptional start point was mapped to a position of 47 base pair from the first ATG codon of translational initiation codon. In order to investigate the inducibility of hrp2+ gene, transcript levels were examined after treating the cells to various DNA damaging agents. The transcripts of hrp2+ were induced by UV-irradiation. But the transcripts were not induced by treatment of 0.25% Methylmethane sulfonate (MMS). These results implied that the effects of damaging agents are complex and different regulatory pathways exist for the induction of this gene.
