Pork industry so far has been focused on growth performance (meat quantity) rather than improvement in meat quality for producing high quality meat. To improve the current meat quality in pork, only the terminal sire is being considered without consideration on F1 breeding sow, since there is technical problems. This study is to survey swine farms and test the performance by breeds to know how to produce high quality pork by using the scientific selection of a breeding pig and the optimal breeding method. Through producing high quality pork, the aim is to allow swine farms to be increased income and consumers to be grown utility. As a result, the most important factor in quality of pork is marbling, and 90% of swine farms have intention of additionally paying for excellent breeding pig. As a result of experimentation, performed targeting Yorkshire, Duroc, and sex on crossbred pigs, the carcass characteristics of Duroc is coincided with general common sense.

Biacetylmonooxime(BAMO)and 3-oximino-2,4-pentanedione(OPDO) were synthesized from methylethylketone and acetylacetone, respectively. Oxime derivatives were synthesized from oximes with benzoylchloide, toluoylchloride, anisoylchloride, and ethylchloro carbonate. And oxime monomers, 2,3-butanedione-O-methacryloyloxime (BMO) and 2,4-pentanedione-O-methacryloyloxime (PMO) were synthesized from methacryloylchloride with BAMO and OPDO, respectively. Photodegradation of oxime derivatives was carried out by the irradiation of UV light in which the free radicals, produced during the photodegradation, could initiate vinyl monomer. The relative decomposition efficiency of oxime derivatives were estimated by comparing UV absorbance decreasing at λmax according to irradiation time. In addition, polymers containing oxime ester in pendant group, P(BMO-MMA) and P(PMO-MMA), were photografted with vinyl monomer, The graft yield of polymers increased with the mole fraction of BMO and PMO.

Bathing beaches may be the one of the resorts in popular, which peoples can easily access in summer. Three beaches located in Jeju island are observed on natural conditions using coastal engineering technique. Also the satisfaction indexs of the sand size, wave height, water temperature, transparency and bottom slope are surveyed. The results obtained can be utilized making an artificial bathing beach.
