This study was carried out to explore the accuracy of near infrared spectroscopy (NIRS) for the prediction of chemical and fermentation parameters of whole crop winter rye silages. A representative population of 216 fresh winter rye silages was used as database for studying the possibilities of NIRS to predict chemical composition and fermentation parameters. Samples of silage were scanned at 1 nm intervals over the wavelength range 680~2,500 nm and the optical data recorded as log 1/Reflectance (log 1/R) and scanned in fresh condition. NIRS calibrations were developed by means of partial least-squares (PLS) regression. NIRS analysis of fresh winter rye silages provided accurate predictions of moisture, acid detergent fiber (ADF), neutral detergent fiber (NDF), crude protein (CP) and pH as well as lactic acid content with correlation coefficients of cross-validation ($R^2cv$) of 0.96, 0.86, 0.79, 0.85, 0.82 and 0.78 respectively and standard error of cross-validation (SECV) of 1.89, 2.02, 2.79, 1.14, 1.47 and 0.46 % DM respectively. Results of this experiment showed the possibility of NIRS method to predict the chemical parameters of winter rye silages as routine analysis method in feeding value evaluation and for farmer advice.

This study aims to investigate purchase attitude towards uniforms, wear condition and their requirements for functional school uniforms for high school boy students, and to help to present basic data for the development of functional school uniforms by reflecting requirements from high school students. First, research on school uniform brands purchased in Busan, Ulsan, and Kyungnam regions showed 2 brands were preferred, and the school uniform purchase expenses are primarily between two hundred thousand won and three hundred thousand won. Second, in terms of differences among fabrics of summer and winter uniforms, many students answered that 'they are similar' or 'there is no difference'. As for complaints about winter uniforms, thermal insulation accounts for the highest rate. As a result of research on underwear worn primarily in the winter, boy students tend to wear underwear to keep their lower bodies warm rather than their upper bodies. They tend to keep their upper bodies warm with outerwear such as vests, cardigans, and padding jumper. According to a survey on experience and satisfaction of functional uniforms, students showed satisfaction with more than three points to all questions except for two, which means their satisfaction about the functions of uniforms that they wear currently is above the average. Third, many boy students complains about the thermokeeping of winter uniforms, especially thigh parts of pants. It is required to make research for the improvement of functional pants for boy students.

Eighty-two ewes of Balochi breed, two to four years of age were used in a completely randomized design to study the effect of winter supplementation on their performance in Kalat area of Balochistan and randomly divided into two groups of 40 and 42 animals. Two treatments (T1 and T2) studied were : 250 gm/animal/day of a 50 : 50 mixture of cottonseed cake and barley grain fed from Oct. 20 to Dec. 18, 1988 plus grazing and 500 gm/animal/day of the same feed mixture fed from Oct. 9 to Dec. 18, 1988 in addition to grazing. Lucerne hay and wheat straw in a 50 : 50 ratio were provided to all the ewes for a period of one month from Jan. 6, 1989 @ 320 gm/animal/day to sustain them in severe winter. Same feeding levels to the same ewe groups were again fed from Mar. 1 to May 27, 1989. Three breeding rams stayed with the flock from Nov. 1 to Dec. 13, 1988. Lambing took place from Apr. 2 to May 12, 1989. Conception, lambing and mortality percentage was found different (P<.05) between T1 and T2 (12.5 vs 14.8 kg). The ewes on T2 maintained higher body weights throughout winter than the ewes on T1. The results are suggestive of improvement in conception rate with winter supplementation (flushing) and decrease in ewe mortality. Late-gestation and early-lactation supplemental feeding of ewes results in increases in weaning weights of their lambs.

This study provides a size specification and ease for the development of pants for working clothes in the construction industry according to season. We collected and measured the size specification of 4 types of Spring/Fall pants, 4 types of winter brushed bonding pants, and 4 types of winter padded pants. Subjective comfort evaluation and analysis of ease sensation were performed for all products on 12 subjects. The average size specifications for the pants according to seasons were as follows. Spring/Fall pants had 74.0/80.0cm waist size (relaxed/maximum stretched) and 104.0cm hip size. Winter brushed bonding pants had 76.0/83.4cm for waist size and 106.0cm for hip size. Winter padded pants had 71.5/84.0cm for waist size and 112.8cm for hip size. When designing a pattern by comparing product size specification and subject body size, the recommended ease is 0.2/7.2cm for waist size (relaxed, maximum stretched) and 13.6cm for hip size for Spring/Fall pants, and 0.2/6.2cm for waist size and 11.6cm for hip size of winter brushed bonding pants, and -5.3/7.2cm for waist size and 19.4cm for the hip size of winter padded pants.

Winter wheat is susceptible to several fungal pathogens throughout the growing season and foliar fungicide application is one of the strategies used in the management of fungal diseases in winter wheat. However, for fungicides to be profitable, weather conditions conducive to fungal disease development should be present. To determine if winter wheat yield response to fungicide application at the flowering growth stage (Feekes 10.5.1) was related to the growing season precipitation, grain yield from fungicide treated plots was compared to non-treated plots for 19 to 30 hard red winter wheat cultivars planted at 8 site years from 2011 through 2015. At all locations, Prothioconazole + Tebuconazole or Tebuconazole alone was applied at flowering timing for the fungicide treated plots. Grain yield response (difference between treated and non-treated) ranged from 66-696 kg/ha across years and locations. Grain yield response had a positive and significant linear relationship with cumulative rainfall in May through June for the mid and top grain yield ranked cultivars ($R^2=54%$, 78%, respectively) indicating that a higher amount of accumulated rainfall in this period increased chances of getting a higher yield response from fungicide application. Cultivars treated with a fungicide had slightly higher protein content (up to 0.5%) compared to non-treated. These results indicate that application of fungicides when there is sufficient moisture in May and June may increase chances of profitability from fungicide application.

Climate temperature affects animal production. This study was conducted to evaluate whether climatic conditions affect beef carcass characteristics of Korean cattle steers. The monthly carcass characteristics of Korean cattle steers (n = 2,182,415) for 8 yr (2006 through 2013) were collected from the Korean Institute for Animal Products Quality Evaluation. Daily climate temperature (CT) and relative humidity (RH) data were collected from the Korean Meteorological Administration. Weather conditions in South Korea during summer were hot and humid, with a maximum temperature of $28.4^{\circ}C$ and a maximum RH of 91.4%. The temperature-humidity index (THI), calculated based on CT and RH, ranges from 73 to 80 during summer. Winter in South Korea was cold, with a minimum temperature of $-4.0^{\circ}C$ and a wind-chill temperature of $-6.2^{\circ}C$. Both marbling score (MS) and quality grade (QG) of Korean cattle steer carcasses were generally best (p<0.05) in autumn and worst in spring. A correlation analysis showed that MS and QG frequencies were not associated (p>0.05) with CT. Yield grade (YG) of Korean cattle steer carcasses was lowest (p<0.05) in winter (November to January) and highest in spring and summer (May to September). A correlation analysis revealed that YG frequency was strongly correlated ($r{\geq}0.71$; p<0.01) with CT and THI values. The rib eye area, a positive YG parameter, was not associated with CT. Backfat thickness (BT), a negative YG factor, was highest in winter (November and December). The BT was strongly negatively correlated ($r{\leq}-0.74$; p<0.01) with CTs. Therefore, the poor YG during winter is likely due in part to the high BT. In conclusion, YG in Korean cattle steer carcasses was worst in winter. QGs were not associated with winter or summer climatic conditions.

The purpose of this study was to compare clothes-wearing in winter between Korean and Japanese college students and to provide the fundamental data for apparel manufacturers to produce young woman's clothing. A total of 332 Korean female students in the capital area and 347 Japanese female students in Tokyo aged between 19 and 25 were used into data analysis from December 2007 to January 2008. Their majors were Fashion Design and Clothing & Textiles. The questionnaires consisted of 36 questions in total. Their details were as follows: 2 questions about the purposes of wearing clothes in winter, 5 questions about whether or not underwear was worn and its types, 9 questions about the types of wearing outer garments, 17 questions about the types of wearing accessories, and 3 questions about demographic characteristics. The results were as follows: It was found that many female students wore clothes for "a protection purpose" or "an ornamental purpose" in winter. There was significant difference between Korea and Japan. As for the question about whether or not underwear was worn in winter, less Korean students answered than Japanese students that they wore both of upper and lower underwear. More upper underwear was worn than lower underwear. As for the question about the types of wearing outer garments, both Korean and Japanese students answered that they wore 3-layered upper garments in winter most. The types of upper garments worn in winter were different between Korea and Japan. The lower garments worn in winter were different between the two countries as well. The Korean students mainly wore pants while the Japanese students wore skirts. As for the types of accessories, there was significant difference between Korea and Japan about most of the questions about hats and gloves. Korean students wore them more than Japanese students. There was no significant difference between the two countries about whether or not scarves or earmuffs were worn. In both countries, more students wore scarves while less students wore earmuffs.
