  • Although defense standardization is recently becoming more and more active, there are still many obstacles to achieve attainments as planned. On the other hand, national standardization already has been applied as a mandatory rule in the overall industries and R&D programs and is well supported by systematic and specialized national basis. Furthermore, advanced countries, such as U.S.A., England and NATO, are considering defense standardization as a essential element to achieve low cost and highly efficient acquisition system and to enhance interoperability among the allied forces. This study aims to form public opinion in support of importance of defense standardization and to provide the vision and various implementation tasks for improving defense standardization outcome.

  • Development of e-navigation strategy which was proposed by seven member states coordinated by United Kingdom in MSC committee of IMO has been conducted for user needs definition, gap analysis cooperating with NAV, COMSAR and STW sub-committee. After prominent progress of development was done in Correspondence group, MSC 85 has approved the result of the group and conducted the development of e-navigation implementation plan to be finished in 2012. It is necessary to prepare the strategy and plan of our country identifying and perceiving the core objects and basic concept of e-navigation developed in the international community. This paper presents the progress of e-navigation development work until this stage and gives some recommendations for the domestic plan to cope with e-navigation.

  • This experiment was conducted to investigate changes of soybean curd yield according to the extension of soaking time during manufacturing of soybean curd. To investigate those changes systematically, transmission electron microscopy and disc-gel electrophoresis were used. The soybean curd yield was increased from 45.0% to 50.5% and 55.4% respectively as soaking time is extended from 5 hours to 10 and 24 hours. The solid extraction and soybean milk coagulation were also increased according to the extension of soaking time. From disc-gel electrophoresis patterns of soybean milk protein and soybean curd protein, numbers of band were increased and major band thickened by expending the soaking time. Most of high molecular bands of soybean milk protein were transfered to soybean curd. Crude 7S proteins of soybean milk and soybean curd in dis-gel electrophoresis were appeared to be 4 and 5 bands respectively, and crude 11S proteins of soybean milk and soybean curd were appeared to be 9 and 8 bands respectively. Of soybean milk bands, most of 11S component transfered to soybean curd. Transmission electron photomicrographs revealed that the dimension of each protein body became larger and the numbers of spherosome around the protein bodies in unit area fewer by extending the soaking time of soybean.

  • Current design-build contract is the type of joint venture, but performs by separate party which causes change orders due to the lack of communication between design and construction, so it cannot lead the main object which is the integration of design and construction. Furthermore, the current design-build contract is impossible to reduce the project costs by VE at the design development phase because the design proceeds with the fixed price through bidding. Like these limitless, the analysis results of the case of VE in the design-build projects, several problems that are prevented from active design VE are elicited by the project participants. Meanwhile, Ministry of Construction & Transportation decided to enlarge the VE review system lately. Therefore, in this study, it presented model of design VE partnering of design-build and partnering agreements form to apply design VE and to try to be able to lead the design VE to be more successful in public design-build projects.

  • BACKGROUND: Unintentional residual pesticide in soil derived from preceding crops and the transfer to succeeding crops was considered a critical barrier for positive list system (PLS). Thus, an uncertain risk is predicted for ethoprophos applied at cultivation of preceding crop (Korean cabbage) to succeeding crop (spinach). METHODS AND RESULTS: Ethoprophos was treated on soil following the recommended dose and 5 times dose according to the safe use guidelines for Korean cabbage after seeding. On the 4 days after harvesting of preceding crop, spinach was sowed. The initial residual amounts of ethoprophos on soil (7.081-19.493 mg/kg) were decreased to 3.832-7.218 mg/kg until the harvest of Korean cabbage, and then finally decreased to 0.011-0.079 mg/kg after spinach cultivation. The uptake rates of ethoprophos from soil by Korean cabbage were 0.01-0.03% and distributed to root (0.150-0.903 mg/kg) and shoot (0.021-0.151 mg/kg), respectively. The residual amounts of uptake and translocation from preceding crop cultivated soil to spinach edible part were found to be below LOQ. CONCLUSION: The plant back internal (PBI) for ethoprophos is not recommended during sequential cultivation of leafy vegetables, since the residual amounts of ethoprophos in spinach were less than MRL (0.02 mg/kg).

  • Involvement of the facial nerve(herpes zoster oticus, Ramsay Hunt Syndrome) is a rather common clinical syndrome. It begins with unilateral ear pain, followed shortly by a peripheral facial palsy. Paresis or paralysis may affect the muscles of facial expression, which also close the eyelids. The levator palpebrae which is innervated by the 5th cranial nerve is spared, so the eye may remain open. The rash is usually confined to the tympanic membrane and the external auditory canal. It may spread to involve the outer surface of the lobe of the ear, anterior pillar or the fauces and mastoid. There also may be a loss of taste in the anterior two thirds of tongue. At time, the auditory nerve involvement produces tinnitus, deafness and vertigo. The 5th, 8th and 10th nerves and even the upper cervical spinal nerve can be involved presumedly on the base of spread of the infective process along anastomotic connections between the facial nerve. The facial paralysis is identical to that of Bells palsy. Frequently the recovery of facial nerve function is incomplete, leaving the patient with some residual facial weak ness. We experienced 2 cases of Ramsay Hunt Syndrome. The first patients, 55 year old male, visited our pain clinic on the day when his left facial nerve start to paralyze. We injected 6 ml of 0.25% bupivacaine into his left stellate ganglion 15 times. TENS was also applicated simultaneously. His facial paralysis was recovered completely 3 weeks after treatment without any complications. Another one, 53 year old male, visited us 7 weeks after onset of facial paralysis. He has been treated conventional oriental method(acupuncture, massage, warm application, etc). But the degree of his left facial paralysis didn't improve at all He has been treating with SGB 50 times and TENS for 2 months. Temporal and zygomatic branch of his left facial nerve recovered nearly completely but buccal and mandibular branch did not recover completely. We are willing to insist on the early treatment is the best choice in managing of Ramsay Hunt Syndrome.

  • BACKGROUND: Pesticides can persist in soil due to multiannual uses. To decrease the concerns for potential carry-over of such residues from treated soil during preceding crop cultivation to non-target crops grown in rotation, an uptake study of procymidone was conducted under the actual cultivation conditions in Korea. METHODS AND RESULTS: Procymidone was sprayed twice by foliar application with recommended and double dose according to the safe use guidelines for Korean cabbage up to 14 days before harvest. Arable land was kept fallow for 4 days after harvesting Korean cabbage, and spinach was cultivated as a succeeding crop. Initial residues in soil were 5.670-14.175 mg/kg that were degraded to 3.098-4.555 mg/kg until harvest of Korean cabbage, and then persisted at 1.026-1.300 mg/kg by spinach harvest. Procymidone residues in edible part of succeeding crops from soil uptake were in range of 0.020-0.048 mg/kg for recommended dose and 0.055-0.116 mg/kg for double dose. Root concentration factor (RCF) values of procymidone at different concentration ranged from 0.053 to 0.123, and translocation factor (TF) ranged from 0.176 to 0.768 for spinach. The value of TF was higher than RCF, indicating that the capability of translocation to shoot was relatively higher than that of root uptake and accumulation. CONCLUSION: Procymidone applied on Korean cabbage can be carried-over to spinach and detected at a level similar to MRL (0.05T mg/kg). Therefore, this study suggests a follow-up study for establishment of plant back interval (PBI) of succeeding crops reflecting the actual agricultural conditions as this study.
