Volatile flavor components of two strawberry (Fragaria ananassa Duch.) varieties, Bogyojosaeng and Suhong, ere extracted by SDE(Simultaneous steam distillation and extraction) using a mixture of n-pentane and diethylether (1:1, v/v) as an extract solvent. Analysis of the concentrate by capillary gas chromatography and gas chromatography-mass spectrometry led to the identification of 146 and 153 components in Bogyojosaengand Suhong respectively. There were 49 esters, 25 alcohols, 20 ketones, 24 aldehyds, 6 acids, 9 terpenes and terpene derivatives, 2ethers, 11 unknowns and miscelaneous in Bogyojosaeng and 67 ethers, 9 unknowns and miscellaneous in Suhong. Among these, (E)-2-hexenyl acetae (4.56%) in Bogyojosaeng and (E)-nerolidol (12.38%) in Suhong were major compounds and aceticacid, (E)-2-hexenal, hexyl acetate, ethyl acetate, ethyl butanoate, methyl butanoate, ethyl hexanoate and ${\gamma}$-dodecalactone were the main components in each sample, though there were several differences in composition and threshold of volatile compounds. Total contents of volatile components isolated and identified in Bogyojosaeng an Suhong were 9.010 and 12.527 mg/kg, respectively.

Mycological characteristics of Phytophthora nicotianae var. nicotianae SPC10 (A1 type) causing Phytophthora rot of strawberry and the resistances of 11 strawberry cultivars against the pathogen were examined. Optimum temperature for the mycelial growth of the pathogen was obtained in the range of 30~35$^{\circ}C$, and the growth was completely stopped under 13$^{\circ}C$ or over 42$^{\circ}C$. Aerial mycelia were abundant on oatmeal agar (OMA), V-8 juice agar (V8A) and lima bean agar (LBA) medium, although there were slight differences, however, on cornmeal agar (CMA) medium, it was a shape of stellate without aerial mycelia. The colony shape on potato dextrose agar (PDA) medium was rough and irregular whereas the mycelial growth was slow, and some aerial mycelia were only produced in the middle of PDA medium. Optimum temperature for sporangial formation was 3$0^{\circ}C$, and zoospores were mostly released at $25^{\circ}C$ from the sporangia. Sporangia were more produced in C/Z solution with pH 5. 0~6.$0^{\circ}C$ than sterilized distilled water (DSW) and distilled water (DW), and zoospores were also released much more than other solutions. Eleven strawberry cultivars such as Reiko, Hokowase, Eyeberry, Akaneko, Sistakara, Toyonoka, Nyoho, Sulhong, Suhong, Myhong and Wonkyo #3104 revealed the disease incidence up to 88.9~100% by the leaf inoculation with mycelial disk. However, Nyoho and Suhong showed higher level of resistance against the pathogen by root inoculation.

We present selfie stick case design, which can protect upper part of Selfie Stick. Many of current products are damaged when it is carried without cases, especially upper part of the product, because protection case is irrelevant to handle in urgent or frequent use of the product. To solve this problem, we design the case part which is attached to stick. For designing the part, we considered functionality, aesthetics, portability and profitability.

The purpose of this study was to examine the effects of a child's demographic variables and maternal perceptions of the conditions of happiness on their happiness for mothers. The participants of this study comprised 916 mothers of young children, school-aged children, and adolescents. The results revealed that a child's age and the numbers of children influenced maternal happiness when mothers' demographic variables were controlled. In addition, mothers who exhibited high degree of need in terms of the conditions of happiness regarding existence, relatedness, and growth were more likely to be happy than mothers who exhibited low degree of needs. Finally, the expectations regarding growth, which refers to the pursuit of self-accomplishment and meaning, was the most important predictor of maternal happiness. These findings have implications for parent education programs for mothers of young children, school-aged children, and adolescents.

Twenty two different disease on strawberry have been reported in Korea. Their occurrence patterns were depended on the varieties cultivated. Fusarium wilt occurred seriously on var. Hokowase, a variety used for the fields or semi-forcing culture. In recent years, however, anthracnose occurred remarkably as the acreage of forcing culture increases. Consequently, anthracnose reduced the stand rate and yield of the strawberry. Average occurrence rate of anthracnose was 36.9% on major strawberry cropping areas. Nyoho and Akihime, which are popular varieties for the forcing culture, are considered to be susceptible, but Holiwase and Suhong are resistant against this disease. Colletotrichum gloeosporioides and Glomerella cingulata have been reported as casual agents for this disease in Korea. C. gloeosporoides was recently reported, but C. fragariae, known to be a strong pathogen in foreign countries, has bot been found yet in Korea. These two fungal pathogens showed significant differences in some characteristics such as major infection parts of plant and responses to temperatures as well as benomyl resistance. In addition, C. gloeosporioides is more pathogenic than G. cingulata. Because vinly sheltering is effective for control of anthracnose to protect water disposal of the pathogen during the seedling stages, it is strongly recommend to use this method in conjunction with integrated control programs.

Colletotrichum gloeosporioides and Glomerella cingulata are the most important pathogens causing anthracnose which may reduce the stand rate and yield on wide kinds of plants including strawberry. Average occurrence rate of anthracnose is 36.9% on major strawberry cropping areas in Korea. We newly found that C. gloeosporioides which does not forming a sexual stage, infects strawberry and differs in some characteristics concerning virulence, cultural and morphological properties to G. cingulata which has a sexual stage. C. gloeosporioides was mainly isolated from the crown with 35.2% rate, while G. cingulata was largely isolated from petiole, runner with 40.9% rate in infected strawberry plants. These two pathogens showed significant differences in cultural characteristics such as perfect stage formation, temperature response as well as benomyl resistance. It was demonstrated that C. gloeosporioides has significantly stronger pathogenicity than G. cingulata in pathogenicity test carried on strawberry plants to various strawberry cultivars. Akihime, Akaneko and Nyoho forcing cultured strawberry cultivars, considered to be susceptible, while semiforcing cultured cultivars, such as Suhong and Holowase, were shown resistant to both pathogens. In non-wound inoculation, C. gloeosporioides was shown pathogenicity on the apple fruit, but G. cingulata could not infect it.

Objective: This study was conducted to apply skin mobilization to patients with Axillary web syndrome following breast cancer resection and to see the resulting changes in pain and joint range of motion. Design: Single case study,pre-post comparison. Methods: The subject was a female patient in her 40s who performed a mastectomy after being diagnosed with breast cancer, and then complained of uncomfortable pain from the shoulder joint to the axilla and limited range of motion. To implement a skin mobilization, the palms were adhered to the inner half of the arm, the arms were raised to a pain-free extent, and skin mobilization was performed. The skin was pulled in the direction of axilla and kept for 5 seconds 10 times for a total of 2 sets. Immediate changes in range of motion and pain were identified. Results: Following skin mobilization, there was an immediate increase in range of motion (pre 116°, post 140°) and a decrease in pain (NRS pre 5, post 2). And also uncomfortable pain, which is hard to define in words, also seems to have improved. Conclusions: Skin mobilization, which considers skin mobility for patients with Axillary web syndrome, can be considered for improving range of motion and restoring function in patients with pain due to fibrous bands around veins and lymphatic vessels, and is recommended as a new intervention method not used as a conventional treatment.
