The purpose of this study was to investigate the preferred methods for making summer kimchi as a basic research of making commercial kimchi. Questionnaire were collected from 590 housewives nationwide in Korea, and the data were analyzed by SPSS program. The results were as follows: (1) The average salting time of Chinese cabbage was 3~5 hrs when the combined method of dry and brine salting was used, regardless of the region. (2) Seven jeotkals (salt-fermented fishes) including anchovy, anchovy juice, shrimp, northern sand lance juice, hair-tail viscera, flatfish and yellow corvenia were mainly used in kimchi. Among them, anchovy and anchovy juice jeotkals were preferred to all others in Southern area (Busan, Gwangju, Gyeongnam, Gyeongbuk, Jeonnam), while shrimp jeotkal in Seoul, Gwangju, Jeonbuk, Chungnam and Jeju, and northern sand lance juice jeotkal in Daegu, Daejeon and Gyeonggi, respectively. In most regions, however, blending type of 2 jeotkals was used in kimchi. (3) Eleven ingredients such as red pepper, garlic, ginger, green onion, radish, leek, onion, carrot, sugar, sesame and MSG were used as basic components for making kimchi. In particular, MSG was used as a basic ingredient regardless of region and age. However, a standard taste for making kimchi was depended on housewife in this study.

For the development of better Gulbi processing, brine salting method was applied for the Yellow croaker (Larimichthys polyactis). The changes of moisture contents, salt contents, and total microbial numbers in Yellow croaker were measured following different brine concentration (20, 30%), temperature (5, 25, 35$^{\circ}C$), and soaking time (1, 6, 12, 24 hours) by brine salting method. Rate of salt penetration into Yellow croaker muscle increased as higher brine concentration and higher dipping temperature. When compared to commercial products of Gulbi by dry-salting method, the moisture and salt contents in Yellow croaker showed similar values after treated with 20% brine at $25^{\circ}C$ for 1 hour. The weight of Yellow croaker increased about 4% when immersed it in 20% brine at 5$^{\circ}C$ for 24 hours. There was no weight change at $25^{\circ}C$ dipping temperature and reduced 7% of weight at 35$^{\circ}C$ dipping temperature. At 30% brine concentration, the weight of Yellow croaker reduced 1%, 9%, and 13% on weight at 5$^{\circ}C$, $25^{\circ}C$, and 35$^{\circ}C$, respectively. Total microbial counts in Yellow croaker muscle soaked at 30% brine showed 1 log lower numbers than 20%. The muscles had about 1 log higher microbial numbers than the treated brine solution. An ethanol extract of onion peel added to brine for giving better color and for preventing oxidation on Gulbi lipid. The treated group showed higher Land b values on Gulbi surface as well as antioxidant effect on the extracted oil.

A study was performed to analyze the biochemical composition (moisture, protein, fat, ash, salt value, iron, calcium and phosphorus) of raw and salted hilsa. Pure (with less than 1% impurities) and clean dry salt was used (fish weight : salt weight = 3 : 1) for salting the hilsa. The nutrients values of the hilsa from two different regions were significantly (p < 0.05) varied. The biochemical compositions were also different before and after the processing of the hilsa. Riverine hilsa contains relatively more moisture ($57.79{\pm}0.51%$) and protein ($15.65{\pm}0.50%$) than marine hilsa. Fat ($16.39{\pm}0.51%$) and salt ($1.80{\pm}0.14%$) contents are higher in marine hilsa; whereas the ash ($7.88{\pm}0.35%$) content was higher in the riverine hilsa. Minerals like iron ($4.92{\pm}0.32mg/100g$) and calcium ($480.02{\pm}6.73mg/100g$) remain in large amounts in the marine hilsa, but the phosphorus ($112.36{\pm}4.40mg/100g$) content remains at a high level in the riverine hilsa. In addition, the protein (raw condition, $18.54{\pm}0.46%$, riverine; $17.12{\pm}0.42%$, marine and salted condition, $32.54{\pm}0.5%$, riverine; $27.31{\pm}0.48%$, marine) and fat (raw condition, $15.41{\pm}0.46%$, riverine; $19.07{\pm}0.51%$, marine and salted condition, $11.58{\pm}0.39%$, riverine; $13.6{\pm}0.55%$, marine) contents were higher in the abdominal region of the riverine and marine hilsa both in the raw and salted conditions than in the head and caudal region.

In order to improve the quality of salted sea mustard, the conditions of blanching, salting, and storage were examined. The process in which sea mustard was blanched for 20 seconds in boiling seawater, soaked in saturated brine solution for 20 hours and then salted for 10 hours by the spreading 10~20% (w/w) of granulated dry salt to obtain the moisture content of about 60% or below, resulted a good color retention of chlorophyll and carotenoid pigments, and organoleptic quality. The shelf-life of the product estimated by 30-40% pigment retention was 50-60days when stored at $4^{\circ}C$ or below.

Double cropping system of oilseed crops introduced rape and castor bean was studied in the newly reclaimed tidal land of Korea. Surface soil EC to reach at 50% of growth reduction to the tallest height of crops was estimated $4dS\;m^{-1}$ for castor bean and $6dS\;m^{-1}$ for rape by logarithmic function. The castor bean cultivated during rainy summer much more suffered serious growth and yield reduction by flooding damage in the Hwaong and Yeonsangang reclaimed lands having low soil conductivity and finer textured soil than in the Iweon reclaimed land having higher soil conductivity and coarse sandy textured soil. Rape cultivated during dry winter-spring much more suffered serious growth and yield reduction by high soil salinity come from re-salting process. 50% yield reduction was estimated at $2.0\;2.5dS\;m^{-1}$ of surface soil EC by logarithmic function. Consequentially, it was concluded that oilseed production for energy by double cropping system of rape and castor bean might be possible under good controling soil salinity below $4dS\;m^{-1}$ for castor and $3dS\;m^{-1}$ for rape in the newly reclaimed land of Korea.
