Purpose: It is well known that a terminal cancer condition affects not only patient themselves but their family members because the patients experience a variety of symptoms. This study was aimed to investigate modifiable factors that influence family caregivers' quality of life, depression, and anxiety. Methods: From January 2015 through May 2015, a survey was conducted with 61 family caregivers of hospice patients who were hospitalized in two university hospitals and one municipal hospital in Busan. The questionnaire was consisted of characteristics of family caregivers and patients, the Korean version of the Caregiver Quality of Life Index-Cancer (CQOLC-K), Beck's Depression Inventory II (BDI-II), Beck's Anxiety Inventory (BAI), and patient's symptom controlling scores rated by family caregivers. Results: Family caregivers' depression was associated with religion. Quality of life and depression of family caregivers were also influenced by monthly household income. Patient age was inversely related to family caregiver's quality of life ($r_s=-0.259$, P=0.043). Family caregivers' quality of life was associated with patient's anxiety (r=0.443, P=0.001). Family caregivers' depression was affected by patient's constipation (r=0.276, P=0.046), anxiety (r=0.508, P<0.001), and daytime drowsiness (r=0.377, P=0.005). And family caregivers' anxiety was influenced by patients' sleep disturbance (r=0.276, P=0.046), depression (r=0.297, P=0.031), and anxiety (r=0.357, P=0.009). Conclusion: According to our findings, family caregivers had higher quality of life and less depression and anxiety when symptoms in hospice patients were well controlled.

This study was conducted to examine the effect of several pretreatments and holding solutions on the vase life and quality of cut Polygonatum odoratum var. pluriflorum for. variegatum stems native to Korea. Postharvest foliar spray of 200 $mg{\cdot}L^{-1}$ $GA_3$ or 200 $mg{\cdot}L^{-1}$ BA + 200 $mg{\cdot}L^{-1}$ $GA_3$ markedly extended the vase life of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum. These treatments maintained high chlorophyll contents as compared with the control (distilled water) during senescence of cut stems. Postharvest pretreatment (dipping) with 100 $mg{\cdot}L^{-1}$ $GA_3$ or 3% sucrose + 200 $mg{\cdot}L^{-1}$ 8-hydroxyquinoline sulfate (HQS) + 100 $mg{\cdot}L^{-1}$ $GA_3$ for 16 hours extended vase life of cut stems 2.5 times as long as nontreated control. Holding solution of 2% sucrose + 200 $mg{\cdot}L^{-1}$ HQS + 100 $mg{\cdot}L^{-1}$ $GA_3$ significantly extended vase life by 3.5 times and increased fresh weight as compared with control. $GA_3$ were very effective on preventing leaf yellowing of cut Polygonatum odoratum var. pluriflorum for. variegatum stems. Postharvest foliar spray of 200 $mg{\cdot}L^{-1}$ $GA_3$ or holding solution of 2% sucrose + 200 $mg{\cdot}L^{-1}$ HQS + 100 $mg{\cdot}L^{-1}$ $GA_3$ markedly extended vase life and improved quality of cut stems of Polygonatum odoratum var. pluriflorum for. variegatum.

This study was conducted to find out the optimum container for increasing acclimatization rate of in vitro mass propagated plantlets of Ever-bearing strawberry (Fragaria ${\times}$ ananassa Duch.) via bioreactor. Four types of containers were used such as transparent plastic container (TPC), plug tray (PT), I-pot (IP), and black vinyl pot (BVP). Number of date maintaining soil water content above 10% was five days in TPC, three to four days in BVP, two days in PT, and one day in IP. Survival rate of plantlets was 80% in BVP, 70% in TPC, 55% in IP, and 15% in PT. In TPC, growth increment of plantlets was the greatest among all the tested containers and the lowest in IP. Numbers of runner per plant were 3.3 in BVP, 2.9 in TPC, 1.6 in PT, and 1.2 in IP. Total cost was 44,405,300 won/10 a in BVP, resulting in reducing more 6,659,400 won/10 a than IP's (51,064,700 won/10 a). Around 102,718 plants/10 a were produced by using BVP, suggesting that 30,265.1 plants/10 a more could be produced than IP (72,452.9 plants/10 a). Production cost per plant was 432.3 won in BVP, resulting in reducing 272.5 won than IP's (704.8 won). As a result, BVP was appropriate for acclimatization of in vitro plantlets through bioreactor system.

Stable production of fermented kanjang containing 1.8% (v/v) ethanol was obtained within four days using traditional kanjang containing 4% added glucose in packed-bed bioreactor systems filled with immobilized Zygosaccharomyces rouxii and Candida versatilis on porous alumina ceramic bead carrier at $28{\pm}0.5^{\circ}C$ and aeration rate of 0.05 vvm. Specific rates of alcohol production for Z. rouxii and C. versatilis were 0.0033 and 0.0031/day, respectively, and those of glucose consumption were both -0.0087/day in the batch type of alcoholic fermentation. In semi-continuous alcoholic fermentation at a dilution rate of 0.25/day, specific rates of alcohol production for Z. rouxii and C. versatilis were 0.0045 and 0.0029/day, and those of glucose consumption were -0.01 and -0.008/day, respectively, using identical bioreactor system. Similar specific rates of alcohol production were observed both in the batch or semi-continuous process and in the continuous one at the dilution rate of 0.25/day. Sensory characteristics of all alcoholic-fermented kanjang by Z. rouxii, C. versatilis, and a mixture of both yeasts (2:1, w/w) were shown to be significantly superior to those of home-made kanjang as revealed through organoleptic evaluation tests (p<0.05).

The purpose of present study was to determine whether different kinds of curing lights can alter microtensile bond strength(MTBS) of class I cavity pulpal and axial wall specimens in primary molar. Thirty clean mandibular 2nd primary molar's occlusal enamel were removed and class I cavity, size of $2{\times}4{\times}2mm$ was prepared. Dentin bonding agent was applied according to manufacturer's manual. Each group was cured with Halogen Curing Unit, Plasma Curing Unit and LED Curing Unit. Composite resin was bulk filled and photo cured with same curing unit. MTBS specimens which size is $0.7{\times}0.7{\times}4mm$ were prepared with low speed saw. Specimens were coded by their curing lights and wall positions (Halogen - Axial wall group, Halogen - Pulpal wall group, Plasma - Axial wall group, Plasma - Pulpal wall group, LED - Axial wall group, LED - Pulpal walt group). MTBS were tested at 1 mm/min cross Head speed by Universal Testing Machine. Fractured surface and bonding surface was observed with SEM. T-test between axial and pulpal specimens in each curing lights, one-way ANOVA among different curing light specimens in each wall positions were done. Weibull distribution analysis was done. The results were as follows : Mean MTBS of pulpal wall specimens were significantly greater than that of axial wall specimens at each curing units(p<.05). There was no significant difference in the MTBS among three curing units at axial wall and pulpal wall. In Weibull distribution, pulpal wall specimens were more homogeneous than axial wall specimens.

The cardiopulmonary and anesthetic effects of tiletamine/zolazepam(TZ, 10 mg/kg IV), xylazine-tiletamine /zolazepam(XTZ, X: 1.1 mg/kg IM, TZ: 10 mg/kg IV) and medetomid-ine-tiletamine/zolazepam(MTZ, M: 30$\mu\textrm{g}$/kg IM, TZ: 10 mg/kg IV) were evaluated to 15 healthy mongrel dogs (4.16$\pm$0.65 kg). These dogs were randomly assigned to the three treatment groups(Control, XTZ, MTZ) with 5 dogs in each group. All experimental animals were premedicated with atropine(0.03 mg/kg, IM). Xylazine or medetomidine were administered to dogs in XTZ group and MTZ group 10 minutes after atropine injection. TZ was administered 20 minutes after atropine injection in all groups. The loss of pain response at pedal reflex and ear pinching tests in XTZ and MTZ groups were much longer compared with those of Control group(P < 0.01). All dogs in this study showed head rocking and hypersalivation during recovery time. Body temperature decreased progressively during experimental period in all groups, but it was not significant. After TZ injection, heart beat rate significantly increased 10 and 20 minutes in Control group, and 20 and 40 minutes in XTZ group(P < 0.05). Respiratory rate significantly decreased 0,10,20 and 40 minutes after 72 injection in XTZ and MTZ groups. In Control group, systolic arterial pressure (SAP) 20 minutes. diastolic arterial pressure(DAP) 10 minutes and mean arterial pressures (MAP) 10 and 20 minutes after 72 injection significantly decreased(P < 0.05). In XTZ group, SAP, DAP and MAP significantly decreased 20 and 40 minutes after 72 injection(P < 0.05). Thus, it was considered that XTZ and MTZ were useful in a canine surgical treatment that requires long anesthetic duration and deep analgesia.

Garlic (Allium sativum L.) has been used as both food and medicine in many cultures for thousands of years. Garlic cultivars are completely sterile and propagated through vegetative method. Collection of a large number of fertile accessions of these genus is needed to explore genetic variability. In order to investigate genetic variation among Allium species and its possibilities for direct cultivation in Korea, we characterized 12 accessions of A. longicuspis, flowering wild garlic which had collected from Central Asia, the main center of garlic diversity. Most of A. longicuspis accessions showed higher over-wintering and bolting rate, longer scape length and more number of bulbils than Korean landraces cultivar, Danyang and Euiseong, but A. longicuspis accessions exhibited smaller size of bulbs and bulbils. Most accessions of A. longicuspis had more number of cloves per bulb, except K229596 and K248824 than Korean landraces. All the accessions of A. longicuspis from Central Asia had complete bolters having many flowers and topsets in umbel. Further studies of A. longicuspis should focus on securing true seeds through removal of topsets and crosses among accessions to create the genetic variability.
