  • A drug delivery system (DDS) based on nanoparticles has been used as a mediator to improve the efficacy of a drug by controlling the amount of drug released and delivering it to a target place. Chitosan, which is non-toxic and biodegradable, has good biocompatibility and excellent adsorption, so it can be used as a drug delivery vehicle. Valine, the essential amino acids, helps muscle growth and tissue recovery, and along with other amino acids. It lowers blood sugar levels and increases growth hormone production. In this study, Valine was adsorbed on magnetic chitosan which is capable of drug absorption, and Fe3O4-Valine CNPs was prepared through cross-linking with TPP (Tripolyphosphate). And then absorption and release trends of valine were investigated with the Fe3O4-Valine CNPs. Fe3O4, which has relatively high stability, is used to make the drug carrier magnetic so that the drug can be delivered to a target place. At optimal conditions, the absorption and release tendency of Fe3O4-Valine CNP was confirmed by analyzing by UV-Vis through the Ninhydrin test which is the color reaction of amino acids and by measuring the size of the particles, it was confirmed that it is suitable as a drug carrier.

  • When determining a meeting place, it is always a cumbersome problem to select an appropriate store with a short travel time for all participants. In this paper, to solve this problem, we propose an algorithm that recommends the best place and store based on the subway station and develop the system. This system provides a web-based store information registration function that allows self-employed people to register and promote their store, and provides an app-based function to recommend a meeting place to participants. The proposed algorithm reduces the travel time of all participants based on the subway map and improves fairness by using the standard deviation of the required time. In addition, this system presents a new way for self-employed people who have recently relied only on publicity through delivery apps.

  • Purpose - The purpose of this study is to review and analyzes the contract of carriage and delivery/transport document in light of the major changes made to the Incoterms® 2020 rules forced into effect on January 1st, 2020. Design/methodology - This study analyzed responsibility for the loading and unloading of goods under the contract of carriage in Incoterms 2020® rules forced into effect by the ICC from January 1, 2020, and what document must be presented as evidence of delivery by the seller. Findings - A review revealed that in Rule C, the costs of unloading at the place of destination are determined by the terms of the contract of carriage, and in the DAP and DDP rules, if the seller bears the unloading costs, such unloading costs cannot be recovered from the buyer. To settle this issue, the seller needs to make a contract of carriage by sea with the carrier on FI terms. Furthermore, in the case of containerized goods that the FCA should be used, FOB was misused because the seller could not present an on-board bill of lading in the L/C transaction. However, it was confirmed that in FCA, the parties can use an optional mechanism to issue an on-board bill of lading. Originality/value - Incoterms 2020® rules are still widely used in international trade by parties to contract sales around the world, just like Incoterms 2010® rules. This study attempts to reduce or eliminate disputes that may arise from interpretative misunderstandings between the parties in the contract of sales concluded by the seller and the buyer.

  • Introduction Recently, changes in the patterns and concepts of maternity care, in both developing and developed countries have been accelerating. An outstanding development in this field is the number of deliveries taking place in hospitals or maternity centers. In Korea, however, more than 90% of deliveries are carried out at home with the help of untrained relatives or even without helpers. It is estimated that less than 10% of deliveries are assisted by professional persons such as a physician or a midwife. Taking into account the shortage of professional person i11 rural Korea, it is difficult to expect widespread prenatal, postnatal, and delivery care by professional persons in the near future, It is unrealistic, therefore, to expect rapid development of MCH care by professional persons in rural Korea due to economic and sociological reasons. Given these conditions. it is reasonable that an educated village women could used as a "maternity aid", serving simple and technically easy roles in the MCH field, if we could give such a women incentive to do so. The midwife and physician are assigned difficult problems in the MCH field which could not be solved by the village worker. However, with the application of the village worker system, we could expect to improve maternal and child hoalth through the replacement of untrained relatives as birth attendants with educated and trained maternity aides. We hope that this system will be a way of improving MCH care, which is only one part of the general health services offered at the local health centre level. Problems of MCH in rural Korea The field of MCH is not only the weakest point in the medical field in our country hut it has also dropped behind other developing countries. Regarding the knowledge about pregnancy and delivery, a large proportion of our respondents reported having only a little knowledge, while 29% reported that they had "sufficient" knowledge. The average number of pregnancies among women residing in rural areas was 4.3 while the rate of women with 5 or more pregnancies among general women and women who terminated childbearing were 43 and 80% respectively. The rate of unwanted pregnancy among general women was 19.7%. The total rate for complications during pregnancy was 15.4%, toxemia being the major complication. The rate of pregnant women with chronic disease was 7%. Regarding the interval of pregnancy, the rates of pregnancy within 12 months and within 36 months after last delivery were 9 and 49% respectively. Induced abortion has been increasing in rural areas, being as high as 30-50% in some locations. The maternal death rate was shown 10 times higher than in developed countries (35/10,000 live births). Prenatal care Most women had no consultation with a physician during the prenatal period. Of those women who did have prenatal care, the majority (63%) received such care only 1 or 2 times throughout the entire period of pregnancy. Also, in 80% of these women the first visit Game after 4 months of gestation. Delivery conditions This field is lagging behind other public health problems in our country. Namely, more than 95% of the women deliveried their baby at home, and delivery attendance by a professional person occurred only 11% of the time. Attendance rate by laymen was 78% while those receiving no care at all was 16%. For instruments used to cut the umbilical corn, sterilized scissors were used by 19%, non-sterilized scissors by 63% and 16% used sickles. Regarding delivery sheets, the rate of use of clean sheets was only 10%, unclean sheets, vinyl and papers 72%, and without sheets, 18%. The main reason for not using a hospital as a place of delivery was that the women felt they did not need it as they had previously experience easy deliveries outside hospitals. Difficult delivery composed about 5% of the total. Child health The main food for infants (95%) was breast milk. Regarding weaning time, the rates within one year, up to one and half, two, three and more than three years were 28,43,60,81 and 91% respectively, and even after the next pregnancy still continued lactation. The vaccination of children is the only service for child health in rural Korea. As shown in the Table, the rates of all kinds of vaccination were very low and insufficient. Infant death rate was 42 per 1,000 live births. Most of the deaths were caused by preventable diseases. Death of infants within the neonatal period was 83% meaning that deaths from communicable diseases decreased remarkably after that time. Infant deaths which occurred without medical care was 52%. Methods of improvement in the MCH field 1. Through the activities of village health workers (VHW) to detect pregnant women by home visiting and. after registration. visiting once a month to observe any abnormalities in pregnant women. If they find warning signs of abnormalities. they refer them to the public health nurse or midwife. Sterilized delivery kits were distributed to the expected mother 2 weeks prior to expected date of delivery by the VHW. If a delivery was expected to be difficult, then the VHW took the mother to a physician or call a physician to help after birth, the VHW visits the mother and baby to confirm health and to recommend the baby be given proper vaccination. 2. Through the midwife or public health nurse (aid nurse) Examination of pregnant women who are referred by the VHW to confirm abnormalities and to treat them. If the midwife or aid nurse could not solve the problems, they refer the pregnant women to the OB-GY specialist. The midwife and PHN will attend in the cases of normal deliveries and they help in the birth. The PHN will conduct vaccination for all infants and children under 5, years old. 3. The Physician will help only in those cases referred to him by the PHN or VHW. However, the physician should examine all pregnant women at least three times during their pregnancy. First, the physician will identify the pregnancy and conduct general physical examination to confirm any chronic disease that might disturb the continuity of the pregnancy. Second, if the pregnant woman shows any abnormalities the physician must examine and treat. Third, at 9 or 10 months of gestation (after sitting of the baby) the physician should examine the position of the fetus and measure the pelvis to recommend institutional delivery of those who are expected to have a difficult delivery. And of course. the medical care of both the mother and the infants are responsible of the physician. Overall, large areas of the field of MCH would be served by the VHW, PHN, or midwife so the physician is needed only as a parttime worker.

  • In this paper, an interference aware distributed multi-channel MAC (IDMMAC) protocol is proposed for wireless sensor and actor networks (WSANs). The WSAN consists of a huge number of sensors and ample amount of actors. Hence, in the IDMMAC protocol a lightweight channel selection mechanism is proposed to enhance the sensor's lifetime. The IDMMAC protocol divides the beacon interval into two phases (i.e., the ad-hoc traffic indication message (ATIM) window phase and data transmission phase). When a sensor wants to transmit event information to the actor, it negotiates the maximum packet reception ratio (PRR) and the capacity channel in the ATIM window with its 1-hop sensors. The channel negotiation takes place via a control channel. To improve the packet delivery ratio of the IDMMAC protocol, each actor selects a backup cluster head (BCH) from its cluster members. The BCH is elected based on its residual energy and node degree. The BCH selection phase takes place whenever an actor wants to perform actions in the event area or it leaves the cluster to help a neighbor actor. Furthermore, an interference and throughput aware multi-channel MAC protocol is also proposed for actor-actor coordination. An actor selects a minimum interference and maximum throughput channel among the available channels to communicate with the destination actor. The performance of the proposed IDMMAC protocol is analyzed using standard network parameters, such as packet delivery ratio, end-to-end delay, and energy dissipation, in the network. The obtained simulation results indicate that the IDMMAC protocol performs well compared to the existing MAC protocols.

  • The parties in International Sale of Goods including Korean Firms Should note ; The buyer must pay the price for the goods and take delivery of them as required by the contract and CISG. The obligations mentioned in Article 53 are primary obligations which are to be fulfilled in the normal performance of the contract. The buyer has to take delivery at the respective place within a reasonable period after this communication since he cannot be required to take delivery immediately. Refusing to take delivery in case of delay not constituting a ground for avoiding the contract makes no sense, since this would lead to even later delivery. The buyer's obligation to pay the price includes taking such steps and complying with such formalities as may be required under the contract or any laws and regulations to enable payment to be made. International sales contracts frequently prescribe that the buyer has to act in advance, that is before the seller starts the process of delivery. Such acts may be either advance payments or the procurement of securities for payment as letters of credit guarantees. On the other hand, The seller deliver the goods hand over any documents relating to them and transfer the property in the goods, as required by the contract and CISG. The seller must deliver goods which are of the quantity, quality and description required by the contract and which are contained or packaged in the manner required by the contract. Except where the parties have agreed otherwise, the goods do not conform with the contract unless they are fit for the purposes for which goods of the same description would ordinarily be used are fit for any particular purpose expressly or impliedly made known to the seller at the time of the conclusion of the contract, except where the circumstances show that the buyer did not rely, or that it was unreasonable for him to rely, on the seller's skill and judgement. The buyer may declare the contract avoided if the failure by the seller to perform any of his obligations under the contract or CISG amounts to a fundamental breach of contract. The seller may declare the contract avoided if the failure by the buyer to perform any of his obligations under the contract or CISG amounts to a fundamental breach of contract.

  • Through the pandemic, the topography of dining culture is rapidly changing due to the advancement of the food delivery market. Competition in the domestic market is intensifying as Coupang Eats recently surpassed Yogiyo and jumped to second place, and Baedal Minjok(Baemin), the industry's No. 1 company, is also preparing to introduce a subscription system. While the growth of the delivery market is slowing, the use of takeout and pick-up services is increasing due to rising delivery costs and food prices. From Generation Z's perspective, the main factors influencing the active use of app services were identified through prior research as usability and convenience, cost sensitivity, and hedonic motivation. While, they are leading the trend of minimizing spending through 'stepping stone consumption' and delivery pot process instead of choosing a subscription system. Accordingly, we aim to provide customers with a better experience and help strengthen competitiveness by proposing ways to improve and revitalize new delivery apps that reflect the characteristics of Gen.Z. As a result of the expert Delphi survey, we will receive impact evaluation scores in the following order: direct view of accumulated discounts, addition of family benefits, coupon reinforcement, SNS promotion, pick-up walk, in-store promotion, and discount rate display, and review their application to practice. It presents academic and policy implications regarding the food tech market.

  • This design is for the landscape of Busan Yeonje Post Office. The design requirements were: the preparation of an open space, the expression of regional identity, total design concept, and application of environmentally-friendly materials. The Busan Yeonje Post Office is not a just post office building but also a place for people including a communications center, rental offices, and a post office, facilities which require publicity, functionality, and symbolism. Therefore, this design reflected the design requirements, and considered the following to include the theme of "Pleasant messages and a pleasant post office with vitality and comfort. First, the open space was to be increased in the adjacent public vacant lot and street park by pulling back the construction line. In this way, the publicity, accessibility, and spatiality of the prepared open space were strengthened. Second, a sense of place for the landscape was expressed through the image of a wave representing Busan, a coastal town. Recognition of the space was strengthened, while regional identity and the concept of transmission of information were expressed. In addition, Citrus junos Sieb., representing 'Happy news' was Planted as a symbolic tree to denote a meaningful resting Place. Third, with respect to the design of reception facilities, considering the general purposes of the construction, post office stamps, envelopes, and postal delivery persons were portrayed on the walls, decorative walls, and environmental formations respectively The flooring was decorated with stamps and waves in keeping with of the total design concept. Fourth, to select environmentally-friendly materials, soil block and eco-grass block were introduced as major paving materials, and folk kinds of trees were included on site. According to the aforesaid plans, the researcher attempted to convert the public agency and office space characterized by feelings of dullness and rigidity into a soft and vivid outdoor space. It is expected that the location will be an open place in the downtown area and be recognized as a 'shared' space for citizens of Yeonje-gu.

  • This study was performed to determine lunch eating patterns and compare dietary habits among university students according to major lunch place. The subjects were 800 students from a university in Gyeonggi-do, and information was obtained by self-administered questionnaire. Data were compared among groups according to major lunch place (school cafeteria n=236, off-campus private restaurant n=73, on-campus private food shop n=134, delivery food n=119, convenient store n=238). Compared to male students, more female students ate at convenient stores (37.8% vs. 17.5%, respectively) while less ate at school cafeterias as the major lunch place. The on-campus private food shop group (19.1 year) were younger than the other groups (20.4~20.8 year). Dietary habits were significantly better in the school cafeteria group (65.55 out of 100) than in the other groups (60.33~62.66) (P<0.01). However, the satisfaction with school cafeterias was significantly lower than those with the other lunch places (P<0.01), and the most frequently answered reason for dissatisfaction was "not taste good" (51.0%). Despite having the lowest satisfaction among the five lunch places, eating at school cafeterias may be associated with better dietary habits in university students. Therefore, this study is able to provide basis for encouraging school cafeteria utilization for university students and for strategy development to improve university students' lunches.
