The meaning of "added value" refers to the contribution of the factors of production, i.e., land, labor, and capital goods, to raising the value of a product and corresponds to the incomes received by the owners of these factors. The importance of added value in service industry has been recognized as one of the critical factors to economic growth, even in logistics industry. But, it is hard to find out the previous studies providing a clear definition and framework for designing and analyzing the performance of Value Added Logistics(VAL). The purpose of this study is to define the meaning of extended VAL that extensively includes activities initiating and operating the reverse logistics under the closed-loop logistic scheme, and to suggest the framework that describes the partnerships among participants involving in operating the value added logistics. Also, in this paper, we emphasize on the need for investigation of added value logistics definition and framework based on previous academic studies, and examine various value added logistics service activities of current leading 3PL companies across the world. Finally, we suggest the analytic framework for value added logistics throughout closed-loop logistics.

Cleft lip and palate(CLP) is one of the most common craniofacial deformities that requires systemic management involving a multidisciplinary team approach. Although there has been great improvement in the field of cleft surgery, surgical approach alone cannot resolve the various problems in treating cleft lip and palate. Hence the need for presurgical treatment was appreciated and especially, the concept of presurgical nasoalveolar molding was applied to treat unilateral and bilateral cleft lip and palate patients. Presurgical nasoalveolar molding(PNAM) of unilateral cleft mainly aims to recover nasal symmetry while the objectives of pre-surgical nasoalveolar molding in the bilateral cleft are to elongate the columella, to erect the tip of nose, and to reposition the forward displaced premaxillary region. This report covers the case of fraternal twins diagnosed with bilateral cleft. Retraction of the premaxillary region and nasoalveolar molding were conducted for 70 days until cheiloplasty, using elastic bands and nasoalveolar molding appliances. After cheiloplasty, there had been improvements in the length of columella and the position of forward-displaced premaxilla for both patients compared to their initial states. The esthetics was also satisfactory for both the surgery and the parents. In order to maximize the efficacy of the appliance, three components should be in balance; patients' adaptation to the appliance, parents' cooperation and proper selection and careful adjustment of the appliance by the dentist.

In the case of the impacted teeth, the clinician has to consider development of tooth, site of impaction, eruption path, and cooperation of patient. If there are genetic or general factors to effect the eruption of tooth, the clinician treats these first and then takes the early treatment for eruption guidance. If there are physical factors to intercept eruption, the clinician put them off first. However, if there are no factors to effect eruption of tooth and enough space for eruption, the clinician can consider extraction of deciduous teeth, forced eruption and surgical reposition. In case of surgical repositioning, proper time for root development, proper socket formation, and minimal trauma are important for success. This case presents displaced impacted maxillary central incisor with dilacerated root. The development of root is Nolla's stage 7, and the tooth was treated by surgical repositioning. We can observe no root resorption and good healing pattern.

Incidence of crown-root fracture due to traumatic injury, have been reported 3% in the permanent dentiton, 2% in the deciduous dentition. There are two treatment methods for crown-root fractured teeth with pulp exposure, when the fracture line was located under the alveolar crest. One way is the extrusion by orthodontic force the other way is intra-alveolar transplantation which occlusally repositioning of apical fragment in the alveolar socket. Since intra-alveolar transplantation has introduced in 1970s, it was practiced as alternative to orthodontic extrusion. As the result, this method may thoughted that had a good prognosis. As a result of trauma, completely crown-root fracture was occured in the maxillary right central incisor in this case. We couldn't reposition the deepest fracture line above the alveolar crest by the conventional surgical extrusion, because apical fragment was too short. Thus, after extraction of apical fragment, we repositioned it to the socket following demineralized freezed dried bone graft, which possible to support the apical fragment. At the 15-month recall examination, the root still showed normal mobility and there was not observed any in flammatory or replacement root resorption in the periapical radiograph.

The incisors function as instruments for biting and cutting food during mastication. They also support the lips and face and maintain vertical dimension. In addition, they contribute to overall normal arch appearance. They play important role during the articulation of speech and assist in guiding jaw closure. Extraction and space maintenance are the most common treatment for a tooth with poor prognosis. However, in the mixed dentition, extraction of the upper permanent incisors results in many complications, such as resorption of alveolar bone, poor esthetics, pronunciation, and mastication. Considering these various roles of incisors in oral cavity, approach for traumatized incisors, even the ones with poor prognosis, should be considered first prior to simple extraction. The dentist must take into account the age of the patient, growth potential, occlusion, oral hygiene status, economic status and motivation towards dental health in addition to patient compliance. In this case, although the prognosis was predicted to be unfavorable due to short root and mobility, we could save the central incisor using conservative treatment, reposition by orthodontic appliance instead of extraction.

Purpose: On November 15, 2012, sales of OTC (Over-The-Counter) drugs began at convenience stores, which changed the accessibility of some drugs. As a result, the exposure and access patterns of these drugs could have changed. In this study, we reviewed the changes in the characteristics of drug poisoning patients because of the reposition of nonprescription drugs according to the revised Pharmaceutical Affairs Act. Methods: A retrospective study was conducted to evaluate changes in characteristics of drug poisoning patients between 2008 and 2016. A registry was developed by an emergency medical center in a local tertiary teaching hospital, and patients who visited the center were enrolled in this registry. We compared two periods, from 2008 to 2012 (Pre OTC) and from 2013 to 2016 (Post OTC), for type of intoxicant, time from poisoning to visiting the emergency center, intention, psychiatric history, previous suicidal attempt, alcohol status, and emergency room outcomes. The primary outcome was the number of patients who took acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Secondary outcomes were ICU admission rate, mortality rate, and number of patients who visited the ER when the pharmacy was closed after taking acetaminophen and NSAIDs (nonsteroidal anti-inflammatory drugs). Results: Among 1,564 patients, 945 and 619 patients visited the emergency room during pre and post OTC periods. The number of patients with acetaminophen and NSAIDs poisoning decreased from 9.2% to 6.1% (p=0.016). The ICU admission rate and mortality rate in the emergency room did not show significant results in the relevant patient groups, and so was the number of patients visiting ER when the pharmacy was closed taking acetaminophen and NSAIDs. Conclusion: Despite the sales of nonprescription drugs at convenience stores, the number of acetaminophen and NSAIDs poisoning patients decreased.

The purpose of this study is to investigate the changes in the recovery of equipment using full containers loaded with freight instead of direct container transportation according to the sales policy considering the cost of transporting the containers. The EMU operation case was analyzed. The policies implemented by Company A to provide EMU credits depended only on the relative accountability contribution margin per box (RA CMPB) for the profitability of backhaul full freight. Therefore, these policies resulted in limitations in sales based on profitable accountability (PA) CMPB, which is more profitable. Moreover, while some Asian regions have surplus equipment, many Asian destinations to which their freight is exported have equipment shortages. Thus, in some cases, service sales to the regions with surplus equipment generated greater company-wide profits when compared with the return of empty containers or sales to the regions with insufficient equipment. In other words, the conditions for providing EMU credits should be changed, and even the full freight between regions with surplus equipment should be provided with credit amounts in which potential factory and transport costs in a destination are pre-reflected.

A 7-year-old male was refered to Department of Pediatric Dentistry, Wonkwang Dental Hospital for treatment of a traumatic injury to the teeth of the maxillary anterior region of the mouth. His right central incisor presented subluxation and root fracture, the left central incisor had suffered intrusive luxation and root fracture. The initial treatment involved reposition and fixation of the teeth with 0.5mm stainless steel wire and composite resin. The patient was submitted for clinical and radiographic fallow-up. After 4 years, radiographically the right central incisor seemed to be healed by hard tissue union and showed to be indistinct fracture line, intact lamina dura. The left central incisor radiographically was healed by interposition of bone and connective tissue and showed to be distinct horizontal fracture line separating the fragments, and pulp canal obliteration. In clinical examination, the teeth showed a normal response to elective pulp test, percussion and mobility test. Pulp survival after injuries appears to be dependent upon the type of luxation injury, age of patient, stage of root development and degree of dislocation. In this case, the two teeth with incomplete root formation were suffered different type of injury by trauma and has showed different healing aspect.

It has been reported that There is a relatively high incidence of congenital cleft lip and palate among congenital anomalies. Children with the cleft lip and palate confront various problems ranging from feeding difficulties as infants to frequent ear infections, compromised speech, aberrant dentofacial development, malocclusion and esthetic impairment with its unfavorable effects on the psychosocial adaptation of the individual. Management of these patients is a process that starts in infancy and continues on into adulthood. Through a team approach, professionals from various fields convene to assess the needs of the child and to assist the parents in dealing with the situation. A pediatric dentist, one of the team, must advise the parents the way of feeding or make an obturator for normal feeding and weight gain of infants with cleft lip and/or palate. An obturator can aid nursing, stimulate orofacial development, help develop the palatal shelves, prevent tongue distortions, prevent nasal septum irritation, decrease chance of ear infections, expand collaped maxillary segments, constrict the expanded anterior part of the maxilla, reposition the premaxilla, and help the parents psychologically. Three cases of infants with cleft lip and palate were managed with the obturator at the Dept. of Pediatric Dentistry, Kyung Hee University. In all cases, infants showed normal feeding and weight gaining after the insertion of the obturator.

Impaction is defined as a cessation of the eruption of a tooth caused by a clinically or radiographically detectable physical barrier in the eruption path or by an ectopic position of the tooth. The reasons for impaction of the maxillary central incisor are supernumerary tooth, odontoma, ectopic position of tooth germ, dilacerated tooth and so force. Impacted tooth cause space loss due to proximal movement of adjacent tooth, malocclusion, root resorption of adjacent tooth, cyst formation, so careful observation and early detection is important and exact treatment should be applied to prevent these results. The treatment options of impacted tooth include induction an eruption through extraction of deciduous tooth or surgical exposure, reposition of impacted tooth by surgical method or orthodontic treatment. Orthodontic traction is recommended when an eruption does not happen after removal of barrier or surgical exposure, when eruption path is too transpositioned to be corrected spontaneously so eruption does not expected. In these cases, traction of impacted maxillary central incisor was carried out using orthodontic method with closed eruption technique and it showed good clinical results so we report these cases.
