This experiment was conducted to investigate varietal responses to cool temperature (18℃) and short photoperiod (8 hours a day) in a controlled room of phytotron. Five burley tobacco varieties (Nicotiana tabacum L.), Awelius (very early flowering type), Burley 21 and KB 103 (medium), Banket Al and MB 1 (slightly late) and TC 681 (late) were compared in number of leaves per plant and day to flower in different treatment periods (10, 15, 20, 25 and 30 days). The days to flower decreased significantly than the control (in the phytoron with 14hr photoperiods and a minimum temperature 20'c) when the treatment periods were over 15 days for the varieties Aurelius, Burley 21 and KB 103, and 20 days for TC 681, and 30 days for Banket Al, respectively. And also the number of leaves decreased significantly than that of the control when the periods of treatment were over 10 days for Burley 21 and Aurelius, 15 days form 103, and 20 days for TC 681 and Banket Al, and 30 days for MB 1, respectively. The decreasing ratio in the number of leaves per plant under cool temperature and short photoperiod treatments was the lowest in Banket Al and MB 1. Key words : Nicotiana tabacum, cool temperature, short photoperiod.

Purpose: This descriptive study aimed to identify the menstrual cycle characteristics and premenstrual syndrome (PMS) prevalence in Korean young adult women using the retrospective and prospective Daily Record of Severity of Problems (DRSP). Methods: In the first stage, participants included 151 nursing students studying in a university located in Seoul. Data were collected from April 20 to June 2, 2017, using the questionnaire on menstrual characteristics, pictorial blood assessment chart, and retrospective DRSP. In the second stage, participants included 17 students with PMS, based on the screening conducted in the first stage. Data were collected using the prospective DRSP from May 29 to 2 September 2, 2017. Results: Of the study sample, 104 participants (68.9%) had regular periods. Those with regular periods had 11.97 periods annually with a menstrual cycle of 29.38 days and a period duration of 5.72 days. Fifty-five participants (37.4%) showed menorrhagia. Sixty-four participants (42.4%) were found to have PMS based on their retrospective DRSP. When the ratio of women (52.9%) with PMS shown in the prospective DRSP was used as a positive predictive value, the estimated PMS prevalence was 22.4%. Conclusion: This study provides clinically significant PMS prevalence among Korean young adult women, positive predictive value of the retrospective DRSP, and valid data to basically understand the menstrual cycle characteristics experienced by these women.

The author reared the bandwinged grasshoppers, Oedaleus infernalis infernalis in the growth cabinet controlled as temperature of 25。C and 30。C under the conditiion of photoperiod 16L:8D, light intensity 510$\pm$240lux, relative humidity 65$\pm$3%. The results are summarized as follows: The female has six instars and male five instars. The larva reared in the temperature of 25。C died at the second larva stage, and the development to the third instar was impossible. The developmental periods of the egg stage of both sexes in the 30。C are 24.06 days. In the larval development periods, the fourth statge (19.73 days) was longer than that of any stage, and the second stage has the shortest period (9.9 days) in female. In male, the developmental period (9.59 days). The total developmental periods of female and male from the egg to the fifth instar were approximately 95.02 and 95.04 days, respectively. The total developmental period of female was as long as the period (15.75 days) of sixth instar which is not in the male. The survivorship curve in the temperature of 30。C shows concave type.

This study is concerned with the jang il (　日). The purpose of this study was to trace the origin of jang il and to identify forms and the meaning of it. Significant findings and results of this research can be summerized as follows : It was found that jang il was a kind of brimmed hat with a round crown. People of Han Dynasty period wore jang il. It was favored by the people of Wei Chin (魏晉) Dynasty period of China and was a very popular hat in these periods. It was used by farmers and merchants. It was found that jang il was worn by a tribe of Kang(羌) in prehistorical period. It is considered that jang il of the Chinese, was derived from the people of Kang(羌). In the Tang and Five Dynasty periods women also wore jang il. Women from the upper class appeared used jang il. It appeared that Koguryoreans also used jang il : it was a kind of black wide brimmed hat with a round crown. which can be found in the tomb paintings of Yong Kang(龍崗). A horse rider wears jang il.

Postweaning performance data were obtained on 401 group fed purebred Angus calves from 24 selected sires (12 high and 12 low feed conversion sires) from 1983 through 1986 at the Northwestern Branch of the Ohio Agricultural Research and Development Center. A single generation divergent selection experiment was replicated four times (1983, 1984, 1985 and 1986) to obtain an realized heritability estimate for postweaning feed conversion. The 140-d postweaning period was divided into five 28-d periods. Realized heritability estimates for feed conversion by 28-d periods fluctuated greatly and demonstrated no particular pattern. Heritability was highest for the fourth period (between d 85 and 112 of postweaning period, 0.61). Thus, beef producers could successfully select for feed conversion.

The proximate compositions, quality and physicochemical characteristics of mung-bean cultivars cultivated in the north-central region of South Korea with different seeding periods were evaluated. A significant difference was noted in the proximate compositions and chromaticity of mung-beans according to cultivars and different seeding periods. Crude ash and protein content decreased with the delay in seeding period and a slight increase in carbohydrate content was observed. Redness of the other five cultivars increased with the delay in seeding period except for the cultivar Jangan, while the yellowness decreased in cultivars Geumsung and Jangan. Water binding capacity of the $1^{st}$, $2^{nd}$ and $3^{rd}$ seeding on the cultivar Eoul was 115.15, 99.76 and 96.31%, respectively, and a decrease in the binding capacity was observed with the delay in seeding periods. Water solubility index and swelling power were significantly different among cultivars. Total polyphenol content of $1^{st}$ and $2^{nd}$ seeding on the cultivar Jangan was 8.59 and 8.57 mg GAE/g, respectively, and a decrease was observed with the delay in seeding periods except for the cultivar Sohyeon. Total flavonoid content of $1^{st}$ seeding on the cultivar Jangan was 5.25 mg CE/g, which decreased with the delay in seeding periods. DPPH radical scavenging activity of $1^{st}$ seeding on the cultivars Geumsung and Kyungseon was 2.44 and 2.32 mg TE/g, respectively, which decreased with the delay in seeding periods. The BTS radical scavenging activity of $1^{st}$ seeding on the cultivar Jangan was 6.98 mg TE/g. In the present study, the variations in phenol content and radical scavenging activity were observed to be dependent on the cultivars and seeding periods.

This study investigated the differences in sociodemographic variables, alcoholism recovery, quality of life, empowerment and self-esteem based on different abstinence periods of alcohol use disorder. The study population from seven different regions in nationwide were 207 individuals with alcohol use disorder who had been abstinent. According to previous studies, 207 individuals were classified into different abstinence periods: less than one year, more than one to five years, and more than five years. As a result, the sociodemographic variables affecting differences in groups were gender, age, marital status, and economic activity. In addition, the group that maintained abstinence from alcohol for more than one year showed significant differences in alcoholism recovery, quality of life, empowerment, and self-esteem than those that maintained abstinence from alcohol for less than one year. Regardless of abstinence periods, alcoholism recovery, quality of life, empowerment, and self-esteem showed significant positive correlations. Therefore, the results of this study identified the factors influencing long-term abstinence and effects and suggested the need for alcohol-dependent recovery programs or therapeutic interventions for individuals who abstained from alcohol use.
