Purpose: Canalicular laceration is relatively common due to its exposed, vulnerable location in case of facial trauma. Conjunctivodacryocystorhinostomy has been the standard treatment for canalicular obstruction secondary to unrepaired canalicular laceration. In spite of a high rate of relieving tear-duct obstruction, this method is noted to be associated with low rate of patient satisfaction and a number of complications. The goal of this study is to report the good results of delayed lacrimal stent implantation with Mini Monoka$^{(R)}$ for patients whose canaliculi were not repaired by initial surgery. Methods: From May of 2005 to February of 2007, four patients who underwent delayed lacrimal stent implantation using Mini Monoka$^{(R)}$ in canalicular laceration were retrospectively reviewed. First, the previous scar incision was made over the lower lid and we identified the cut end of proximal lacerated canaliculus. The Mini Monoka$^{(R)}$ was passed through the punctum to the cut end of the proximal lacerated canaliculus. We identified the cut end of the distal lacerated canaliculus, whose cut end has rolled white edges after careful excision of the scarred lid tissue. We then passed Mini Monoka$^{(R)}$ through the lacerated inferior canaliculus. Using an operating microscope, we placed three interrupted sutures of 8-0 Ethilon to join the canalicular ends. Silicone stent was left in place for 6 months. The mean age of the patients was 48.5 years (range, 35 to 59 years). The time interval from initial trauma to delayed lacrimal stent implantation was between 3 and 31 days. Follow-up periods ranged from 12 and 20 months. Results: The results of reconstruction were classified into normal, fair and poor. Patent lacrimal drainage systems were achieved in three of the four cases. In one case, epiphora was encountered. No cases of stent displacement, conjunctivitis or granuloma formation were encountered. Conclusion: Even though canalicular reconstruction was delayed for a long time, attempting canalicular reconstruction would be acceptable before considering secondary operations like dacryocystorhinostomy and conjunctivodacryocystorhinostomy.

This study was undertaken to clarify the relationship between the cause of repeat-breeder and the luteal dysfunction in repeat-breeder dairy cows that failed to conceive to three or more artificial insemination(AI) at a regular interval. Progesterone concentrations were measured in milk fat for 20 to 22 days after AI. From the 15 repeat-breeder dairy cows, six cows had a normal progesterone profiles. Five cows showed a delayed rise of the progesterone concentrations until 7 to 10 days after AI, two cows had a comparatively low concentration of milk progesterone below 150 ng/ml through most of the luteal phase, and two cows had a combined pattern of a delayed rise and a low concentration of milk progesterone during luteal phase. It is suggest that luteal dysfunction as indicated by progesterone profiles is one of the causes of repeat-breeder in dairy cows.

Diaphragmatic hernias have been reported in 0.8%-1.6% of patients who experience blunt chest trauma. The hernia is assumed to form as a result of direct diaphragmatic violation or significant intraabdominal or intrathoracic pressure caused by the trauma. Some reports have described cases of delayed diaphragmatic hernia and subsequent stomach perforation that occurred a few days to several years after an accident. We report an extremely rare case of diaphragmatic herniation in which the process from initial blunt trauma to visceral organ perforation took only 2 days, without any evidence of herniation on the initial X-ray or computed tomography. Delayed diaphragmatic herniation and subsequent visceral organ perforation should not be missed during the period immediately after blunt chest trauma.

Buffalo are a major source of milk production, contributing 12.1% in the World and 38.0% in Asia. The buffaloes are kept under peri-urban farming systems to produce milk for urban populations. Breeding is delayed in these herds to get more economic benefit because farmers believe that the pregnancy decreases milk production. The lactation milk value has been studied in this paper as an economic indicator. Complete milk yield records of 3,304 buffaloes was collected from a group of state farms. Economic traits including lactation yield, lactation length, calving interval (CI), dry period and milk yield per day of calving interval (MYPDCI) were derived from the data. The animals were grouped according to parity number (1-3), service period (G1 to G4, conceiving during <150, 150-200, 200-300 and >300 days post calving) and yield levels (HMY>2,500; MMY 2,001-2,500; and LMY 1,500-2,000 liters/ lactation). To study the effect of pregnancy on milk composition a research trial was conducted at a medium size private dairy farm, using forty lactating buffaloes of three yield levels and four service period groups, as described already. Milk was sampled on alternate weeks and analyzed for fat and protein contents (%). For quantifying the value of milk produced during a lactation period, the value corrected milk (VCM) was determined and converted to lactation milk value (LMV). Group means were compared for varicous parameters. Highest milk yield ($2,836.50{\pm}15.68$ liters/lactation) was recorded in the HMY animals of G4 group while lowest milk yield of $1,657.04{\pm}8.34$ liters/lactation was found in LMY of G1. Lactation was significantly increased with the extending of service period. The shortest dry period was recorded in HMY, parity 1, G1 animals and the longest in parity 2, MMY, G4.The CI was shortest in HMY, parity 1, and G1 animals and longest in LMY, parity 3, G4 buffaloes. The HMY, parity 2, G1 buffaloes showed the highest MYPDCI and the lowest value was recorded ($6.53{\pm}0.17$ vs. $2.76{\pm}0.04$ liter/day) for LMY, parity 1, G4 buffaloes. The VCM decreased with the delayed conception. This decreasing trend was higher in respect of the total yield but decrease in the VCM was smaller due to the increasing levels of fat and protein in the milk. The gap between the various production classes was reduced based on the VCM as compared with the yield per day of CI. LMV showed a consistent decline with extending service period in all three production groups. The study suggests that CI increased with delayed conception, showing a consistent trend in the low, moderate and high yielding buffaloes. There was a coherent declining pattern of milk yield with delaying conception, associated with prolonged CI. An animal conceiving at a later stage of lactation showed a decline in financial returns of 24 to 27% compared with those conceiving earlier.

This study was conducted to determinate the optimum times of transplanting and harvest for enhancing the fresh leaf yield and colorant level of an indigo crop, Persicaria tinctoria H. Gross, containing the blue dye indigo. Two cultivars, Naju Local and a new cultivar, NaramBlue, were transplanted 5 times from May 30 to July 10 at an interval of 10 days, and all of experiment plots harvested on Aug. 23 in Muan, the south area of Korea. As transplanting time was delayed, fresh leaf yield were maximum at earliest transplanting (May 30) and then decreased, while Niram (blue dye extract) and indigo content of fresh leaf remained almost constant though showed a small variation. Also, two cultivars transplanted on May 23 were harvested 5 times from Jul. 20 to Sept. 20 at an interval of 15 days. As harvest time was delayed, plant height, No. of first branches, and fresh leaf yield changed increasingly, while Niram content was increased to Aug. 20 and then decreased slightly. Indigo level increased largely to Aug. 5, and then continuously decreased with more delayed harvest. These tendencies of changes in fresh leaf yield and colorant level with different transplanting and harvest times were shown similarly in both cultivars. The results indicate that early transplanting before May 30 and harvest in early August will be appropriate for improving fresh leaf yield and colorant level.

To evaluate immunotoxicity of skin decontamination kit(SDK) newly-developed in Agency for Defense Development(ADD), delayed contact hypersensitivity (maximization) test and passive cutaneous anaphylaxis(PCA) test of SDK were performed and the results were compared with those of M 291. In maximization test, sensitization reaction was induced by id injection (2.5 mg / 0.1 $\textrm{m}{\ell}$/ guinea pig or 2.5 mg+CFA/0.1 $\textrm{m}{\ell}$/guinea pig) and topical application (2.5 mg/$\textrm{m}{\ell}$/guinea pig) with SDK or M291 at an interval of 1 week, and 2 weeks later, challenged by topical application with 25 mg/$\textrm{m}{\ell}$/guinea pig. SDK and M291 did not induce any reactions, showing 0 point of sensitization score and 0% of sensitization rate. In conclusion, it is suggested that SDK and M291 do not induce delayed contact hypersensitivity. In PCA test, rats were administered id with mouse anti-SDK serum and challenged iv with a mixture of antigen SDK and Evan's blue. SDK did not induce blue spots at the injection sites of both high (2.5 mg/mouse) and low (1.25 mg/mouse) dose-induced antisera. In contrast, BSA, positive control produced spots larger than 5 mm in diameter at the injection sites of BSA-induced antiserum up to $2^2$ ~ $2^4$dilution. In conclusion, it is suggested that SDK do not induce IgE production and is not a PCA-reaction inducer.

Background: Tumors are largely unable to metabolize ketone bodies for energy due to various deficiencies in one or both of the key mitochondrial enzymes, which may provide a rationale for therapeutic strategies that inhibit tumor growth by administration of a ketogenic diet with average protein but low in carbohydrates and high in fat. Materials and Methods: Thirty-six male BALB/C nude mice were injected subcutaneously with tumor cells of the colon cancer cell line HCT116. The animals were then randomly split into three feeding groups and fed either a ketogenic diet rich in omega-3 fatty acids and MCT (MKD group; n=12) or lard only (LKD group; n=12) or a standard diet (SD group; n=12) ad libitum. Experiments were ended upon attainment of the target tumor volume of $600mm^3$ to $700mm^3$. The three diets were compared for tumor growth and survival time (interval between tumor cell injection and attainment of target tumor volume). Results: The tumor growth in the MKD and LKD groups was significantly delayed compared to that in the SD group. Conclusions: Application of an unrestricted ketogenic diet delayed tumor growth in a mouse xenograft model. Further studies are needed to address the mechanism of this diet intervention and the impact on other tumor-relevant parameters such as invasion and metastasis.

Winter green manure crops including legume increase grain yield of subsequent crop and substitute N fertilizer requirement with organic-No Hairy vetch grows vigorously and can provide N-rich green manure for corn with its soil incorporation after wintering. But, grain yield of corn as succeeding crop would be reduced if its planting time is delayed until late spring. This experiment was carried out to find the proper incorporation time of hairy vetch green manure and planting time of subsequent corn in cropping system with winter hairy vetch(green manure)-summer corn. Hairy vetch was incorporated into soil at a ten-day interval between April 10 and May 10 and corn was planted at 5 days after each hairy vetch incorporation. Soil nitrate concentration on April 10 and 20 in hairy vetch plot was slightly lower than that at winter fallow. Above-ground dry matter and organic-N of hairy vetch increased linearly with delayed hairy vetch incorporation time from April 10 to May 10. Average dry matter and organic-N produced by hairy vetch were 5.7 ton/ha and 248 kgN/ha, respectively. Corn growth and yield decreased as delayed corn planting time after May in spite of increasing dry matter and N-yield of hairy vetch. Nitrogen concentration of corn grain, stalk and whole plant at harvest were the highest in May 5 planting, but total N-uptake of May 5 planting were not different from that of April 25 planting because of lower grain yield. It was concluded that the proper incorporation time of hairy vetch and corn planting time were April 20 and April 25, respectively, because grain yield was the highest and corn could use hairy vetch-N effectively to produce dry matter.

This study examines the effects of mindfulness training on job stress, burnout, and teacher efficacy for middle school and high school teachers. For this study, twenty-four middle school and high school teachers were divided into experimental and control groups. Data analysis was performed using a Mixed ANOVA for teacher's job stress, burnout, and teacher efficacy according to pre-training, post-training and delayed post-training periods. As a result, we found support for time interval and between-group interaction effects for all the dependent variables. In order to investigate any delayed effects, a t-test was performed to analyze measurements taken one month after the completion of training period. The delayed post-training results indicated a significant effect between pre and post scores, meaning the program effects were sustained. Therefore, this study indicates that the mindfulness training program implemented in this research is an effective method for preventing job stress and burnout, as well as influencing the efficiency of work performance for middle school and high school teachers.

Potentially lethal damage repair (PLDR) in HFL-I was investigated by delayed plating experiments. The surviving fraction data were fitted to the linear Quadratic equation ($LogSn=-n{\gamma}({\alpha}d+{\beta}d^2$) where ${\gamma}=1$ for immediate plating). And a repair factor ${\gamma}$ was developed to compare survival for immediate and delayed plating. When we only took into account the repair factor of PLDR ${\gamma}$ which was derived from the delay assay, the cell survival response th fractionated carbon ion irradiation was not fully matched. This gap suggested that consideration of another repair process is necessary. So this suggests that the various repair process plays an important role in the fractionated irradiations.
