Zoysia japonica Steud. is a warm-season lawn grass popular in Korea and elsewhere. They are cultivated in many places such as river banks, roadside, and play grounds. However, there still is a disadvantage of frequent mowing, and the grass grows poorly under the chilly conditions. To develop a grass variety that circumvents these drawbacks, we cloned the chitininducible gibberellins-responsive1 gene (CIGR1) from zoysiagrass. The full length of the ZjCIGR1 (Zj; Zoysia japonica Steud.) gene was obtained by 5′/3′ RACE PCR and the phylogenetic tree showed that it belonged to the CIGR1-subgroup in the PAT1-group of GRAS protein family. Expression of the ZjCIGR1 in wild-type plants was confirmed in roots, meristems, leaves, and flowers, especially high in the flowers. The transgenic zoysiagrass was confirmed by PCR using gene-specific primers, phosphinothricin-acetyl-transferase (PAT) strip test, and Southern blot analysis. ZjCIGR1-overexpressing plants acquired tolerance to cold stress displaying morphological phenotypes characteristic of stress resistance. In addition, in the transformants, expression of the ZjCIGR1 as well as cold-regulated (COR) gene was increased compared to the wild-type plants under cold stress condition. These results suggest that ZjCIGR1 gene is an important candidate for regulating cold stress resistance.

C. H. YOUM, Y. H. PARK, K. W. SEO, C. M. YANG. Comparison of the kinematic analysis of grand battement jete ?la second in center between skilled and unskilled ballet majors. Korean Journal of Sport Biomechanics, Vol. 14, No. 2, pp. 153466, 2004. The purpose of this study was to investigate time of the phase, angle of the right ankle, knee, and hip joint, lateral angle of the trunk, mediolateral displacement of COM, and vertical displacement of COM between two groups while executing grand battement jets ?la seconde in a center exercise setting through 3D video analysis. The subjects participated in this study were skilled and unskilled 6 female ballet majors in Busan, respectively. The conclusions are as follows: 1. The time of the phase 2 was faster than P3. It shows a significant difference(p<.05) for P1 and P4 between skilled and unskilled groups. 2. The angle of the right ankle joint has a significant difference(p<.05) at E4 between skilled and unskilled groups. The angle of the right knee joint has no significant difference at all events between skilled and unskilled groups. The angle of the right hip joint has a significant difference(p<.001) at E3 between skilled and unskilled groups. 3. The lateral angle of the trunk has a significant difference(p<.05) at El and at E5 between skilled and unskilled groups. The skilled group of the lateral angle of the trunk was lower than the unskilled group. However the skilled group`s lateral angle of the trunk was bigger than the unskilled group at E3. It has significant difference(p<.001) at E3 between skilled and unskilled groups. 4. The mediolateral displacement of COM has no significant difference at all events between skilled and unskilled groups. The vertical displacement of COM has a significant difference(p<.01) at E3 between skilled and unskilled groups.

In this paper, we analyzed the characteristics of indoor heating environment by the electric panel heating system without thermal storage developed from the traditional under-floor heating system, and compared them with the ones by the electric heating system with thermal storage. From the experimental study, we observed little temperature difference of the upper and lower of space as well as the horizontal temperature distribution. The electric panel heating system makes the constant indoor temperature and more comfortable. However, we observed that the electric heating system with thermal storage is more economical than the electric panel heating system.

Physical properties of wool are closely related to species of sheep, locality of production and feeding conditions. This paper describes an basic investigation of physical properties of Korean wool. Specific properties affected by crimp were also investigated. The experiment for physical properties of Korean wool was carried out by the conventional method and its for specific properties was done by load extension test. The results of those were as follows; 1. As for fineness values of wool, the quality numbers of Corriedale wool was 56's and its of Romney marsh wool was 46's-48's. 2. As for fineness, mean length, distribution of fibre length, strength and elongation of Corriedale wool were superior to those of standard wool. 3. It was found that strength per denier and elastic limit strength of both species were sligtly higher than its of standard wool 4. Uncrimping force was 1/15-1/21 of yield stress, Recovering of uncimping force and enegy in Korean wool was also significant. 5. Corriedale wool has good quality of which uncrimping force and energy would be changed by crimp. Characteristics of Corriedale wool; elasticity, softness and bulking capacity of wool itself were slightly higher than its of Romney marsh wool

Air pollution from auto-vehicle exhausted gas accounts for 70% of entire air pollution in Jeju. The introduction of electric vehicles which do not generate discharge emissions will improve the clean image in Jeju and boost tour industry. Driving tests have been conducted on the 5·16 and Ilju Roads to investigate the driving characteristics of electric vehicles, using Santa Fes provided by HyunDai Motor Co. The state of charging battery decreases rapidly on the uphill road of 546 Road, while it shows linear decreases on the flat road of Ilju Road. It is required to improve the charging ability of battery to adopt the electrical vehicle in Jeju.

Cystic lymphangiomas are congenital lymphatic hamartomas of which half are present at birth, 90% are evident by age 2 years and 95% occur in the neck or axilla. Scrotal cystic lymphangioma is rare with approximately 50 cases reported. The lesion is commonly misdiagnosed as hernia. hydrocele, spermatocele and acute scrotal condition, resulting in improper selection of incision, incomplete excision and recurrence, We present a case of 2 year 9 month old male with the scrotal lymphangioma that have not any connection with the testis or spermatic cord.

Testicular microlithiasis is a rare disease characterized by calcifications within the seminiferous tubules. Testicular microlithiasis has been found with a wide variety of testicular pathology, but to our knowledge its association with torsion of appendix testis has been reported only one case. Therefore, we report on an 13-year-old boy with torsion of testis appendix and bilaterally diffusely echogenic testes on sonography.

Biofeedback and pelvic floor electrical stimulation are new modalities that have been advocated for the treatment of female urinary incontinence. The aim of this study was to compare prospectively the therapeutic effect of Kontinence™(HMT Co., Korea) with Compact Elite™(ECL Co., France) in female urinary incontinence. All patients were evaluated with a complete history, physical examination, urinalysis, urine culture and urodynamic study. Eighteen patients were treated with Compact Elite™, and thirteen patients with Kontinence™. Enrolled patients had completed 8 office sessions consisting of biofeedback and intravaginal electrical stimulation according to the program of each machines. Overall treatment response was graded by patients on a scale of complete cure to aggravation. At two weeks after last session, overall improvement rate was 78% in Compact Elite™group and 92% in Kontinence™group(p>0.05). Overall patients' acceptability during treatment course was greater than 80% in both machines(p>0.05). There were no unexpected clinical findings during Kontinence™ treatment. After Kontinence™treatment, there were no laboratory changes including electrocardiography, complete blood count, liver function profile, and chest PA. These results showed that the biofeedback and electrical stimulation with Kontinence™was safe and moderately effective for female urinary incontinence comparable to Compact Elite™. However, long-term results of a larger patients are needed to ensure the therapeutic effect of Kontinence™.
