10월이 되면 많은 기업들이 차년도 경영계획 수립에 들어간다. 물론 이보다 더 일찍 서두르는 기업도 있지만 대개는 10월부터 시작한다. 물론 12월에 가서 준비하는 기업들도 있을 것이다. 구체적인 계획은 연말 연시에 할지라도 이 즈음에서 내년 경기 전망과 현 시점의 건설 경기 전망을 살펴 보며 미래를 전망해 보는 것은 매우 의미있다고 하겠다.

간이형 휴대전화 시스템 실용화실험 협의회는 국내 전기통신 사업자, 통신장비 제조업체, 관련 정부기관 및 관련단체의 협조와 참여를 통하여 1993년 7월 6일 설립되었다. 이 협의회는 간이형 휴대전화 시스템(PHS)에 대한 실용화실험의 여러 형태에 관련된 정보의 교환을 조정하고, 실용화의 원활한 구현을 촉진하기 위하여 구성되었다. 이들의 활동을 통하여 협의회는 이 새로운 통신 서비스에 대한 공공의 합의를 토대로 실질적인 PHS의 개념을 설정하는 업무를 처리한다. 이 최종보고서는 협의회에 의해서 1993년 10월부터 1994년 10월까지 1년여 기간동안 일본 도처의 여러지역에서 실시된 실용화실험의 결과로 제출되었다. 이 보고서가 더 나은 PHS의 구현에 도움이 될 것을 희망한다.

This study was carried out to find the most suitable soybean cultivars and optimum planting dates by checking yields and other agronomic characteristics in the Jeonbug area. It was observed that seed yields and other characteristics tended to increase for early planting dates, and the correlation between yields and other characteristics seemed to vary with planting dates. Tousan 73 and Williams among the 20 varieties used, appeared to have high yields no matter what the planting date, thus these are the most promising varieties in the Jeonbug area. However, further studies are needed on these varieties of soybeans.

Gonadal maturation and annual reproductive cycle in ovoviviparous oblong rockfish, Sebastes oblangus on the basis of monthly gonadosomatic indices (GSI), hepatosomatic indices (HSI) and histological observations of gonadal tissues. GSI values of female were in a wide range from $0.l5\pm0.0l\;(July)\;to\;58.54\pm3.86$ (December) and began to increase in August and reached the maxium in December, then decreased rapidly thereafter. Male GSI values were in a range from $0.08\pm0.03$ (July) to $1.55\pm0.27$ (September) and began to increase rapidly in July and reached the maximum in September, then decreased gradually, thereafter. Female HSI was in a range from $0.89\pm0.12$ (December) to $3.73\pm0.15$ (October), and male's was from $2.09\pm0.76$ (October) to $3.62\pm0.48$ (August). HSI reached the maximum values one or two months before GSI reached their maxium values in both sex, and then decreased rapidly thereafter. Mature oocytes began to appear in late October as being oocytes began to mature in August, and the type of oocyte development is categorized in the roup-synchronous oocyte development'. Ovulation and fertilization of ripe oocytes occurred in November, and hatched larvae were born from December to January. Maturation of testis was progressed in short term from August to October and spermatozoa were released in October. Sperm balls consisted of many spermatozoa were preserved in ovarian cavity of female after copulation. These results may suggest that the annual reproductive cycle of oblong rockfish could be divided into the following successive stages: growing (August and September), mature (September and October), gestation (November and December), parturition (December and January) and resting (February to July) in female, and growing (August and September), mature (September and October), copulation (October) and resting (November to July) in male.

Field experiment was conducted to examine the winter hardiness and forage productivity of Chinese milkvetch (Astragalus sinicus L.) varieties at the research farm of Korea University in Kyunggi province. Collected variety Nonsan, Imsil, Jangheung, Chungnam, Joongsan and introduced PI241587 were tested to untreated control and vinyl mulching conditions during winter season. Effect of vinyl mulching treatment was found no statistical significance in this experiment. Winter survival of six Chinese milkvetch varieties at the untreated control was average 88%. Variety Nonsan and Imsil showed higher fresh and dry weights than other varieties both on May 6 and 21 harvest. Average fresh weight per l0a of six varieties at the untreated control was 1,583kg on May 6 and 4,017kg on May 21 harvest. Crude protein content of dry matter of the varieties was average 21.3% on May 6 and 19.2% on May 21 harvest. However, average crude fiber content of the dry matter on May 6 was lower than that of May 21 harvest.

Optical properties were studied at the fishing ground of anchovy in the southern part of Korea based on seven oceanographic stations from May to August and November to December, 1977. Submarine daylight intensity was measured at intervals of 1m depth in the upper 30 m layer by the underwater luxmeter (Toshiba # 9). The absorption coefficient of the sea water ranged from 0.066 to 0.619 (mean 0.21) for six months. The transparency ranged from 2.6 to 16 meters (mean 8.4m). The relationship between absorption coefficient (n) and transparency (D) was k=1.70/D. The mean water color in this area was 4.8 $(3\~10)$ in Forel scales. The rates of light penetration for daylight at four different depths were computed with reference to the surface light intensity. The mean rates of light penetration were $69.38\%(25.43\~88.10\%),\;30.35\%\;(4.38\~59.46\%),\;12.53\%\;(0.75\~33.51\%),\;5.7\%(0.18\~20.27\%)$ at depths of 1, 5, 10 and 15 m respectively.
